The system automatically loads all .js files inside this folder and all subfolders recursively. Action names are generated from the folder structure using dot-notation. + +Example: +- websocket/user/getUserData.js → "user.getUserData" +- websocket/system/internal/restart.js → "system.internal.restart" + +Each action file must export an async function: +```js +module.exports = async (data, ws, connectionId) => { + // data = payload from client + // ws = WebSocket instance + // connectionId = internal connection ID +} + +// Detailed example: +module.exports = async (data, ws, connectionId) => { + try { + console.log(`TestAction triggered by connection ${connectionId}`); + console.log('Received data:', data); + + // set response object + const response = { + message: 'TestAction executed successfully!', + receivedData: data, + timestamp: Date.now(), + connectionId + }; + + // send response back to the client + ws.send(JSON.stringify({ + action: 'test.testaction.response', // optional: own response action + data: response + })); + + return response; + } catch (err) { + console.error('Error in TestAction:', err); + + ws.send(JSON.stringify({ + action: 'test.testaction.error', // optional: own response action + data: { message: err.message } + })); + + throw err; + } +}; +``` + +On the client side it looks like this: +```js +// Connect to server +const ws = new WebSocket('ws://localhost:3001'); + +// Send a message +ws.send(JSON.stringify({ + action: 'test.testaction', + data: { foo: 'bar', num: 42 } +})); + +// Get a message +ws.onmessage = (msg) => { + const parsed = JSON.parse(msg.data); + console.log('Server response:', parsed); +}; +``` + +--- + +## Scheduler Service + +The Scheduler service is started via the service manager.

One-time tasks (oneTime: true) execute once after intervalInSec, while recurring tasks (oneTime: false) repeat indefinitely at the specified interval. +- Each task executes the function exported by its action file in ROOT/tasks. Errors are saved in task.error +- The functions in the tasks folder should be `async` to ensure proper execution of asynchronous operations. + +#### Usage +```js +const memory = require('./services/scheduler/memory.js'); // from the ROOT-Directory of the service + +// Load all tasks from tasks.json +// Recurring tasks (oneTime: false) are started automatically +// One-time tasks with active: true also start automatically +memory.loadTasks(); + +// Get a single task +const task = memory.getTask('updater'); +console.log(task); + +// Get all tasks +const allTasks = memory.getAllTasks(); +console.log(allTasks); + +// Add or update a task +// If active: true, the timer starts immediately; if oneTime: true, task executes only once after interval +memory.setTask('cleanup', { + active: true, + oneTime: true, + intervalInSec: 10, // in this case, the interval will set delay + action: 'cleanup' +}); + +// Remove a task +memory.removeTask('cleanup'); +``` + +**Note**: +- The memory object is shared globally. Any changes you make here immediately affect the scheduler service. +- Automatic execution, lastRun/nextRun tracking, and error logging are all handled internally. + +--- + +## Logging Service + +The Logging service is started via the service manager. It provides a central way to write log data into the logging database, using the system write pool. The service can be started, stopped, restarted, and its status can be checked. When offline, no log entries are written. + +### "Service Manager" usage +```js +const services = require('./services/manager.js'); // from the ROOT-Directory of the service + +// Start the logger service +const loggerData = await services.start.logger(); +console.log(loggerData.online); // true if started successfully +const tasks = loggerData.tasks; + +// Stop the logger service +const stopResult = await services.stop.logger(); +console.log(stopResult.online); // false if stopped + +// Restart the logger service +const restartResult = await services.restart.logger(); +console.log(restartResult.online); + +// Check status +const status = await services.status.logger(); +console.log(status); +/* Example output: + { "online": true } +*/ +``` + +### Logger Service Internals +- The logger service maintains a single `online` flag to determine whether logging is active. This is checked before every write to ensure no logs are written while offline. +- When the service is stopped, the `online` flag is set to `false`, preventing any writes to the database. +- Log entries are written dynamically to tables in the `logging` database via the `write()` function. +- The MySQL write pool (`w.s`, `write` method → `system` role) is used internally to insert data. + +#### Writing logs +Logs are written using the exported `write()` function from `ROOT/service.backend/services/logger/writeLogs.js`. This function dynamically maps an object of key/value pairs (`logData`) to columns in a specified table. The service must be online for writes to succeed. + +```js +const logger = require('./services/logger/writeLogs.js'); // from the ROOT-Directory of the service + +module.exports = async (data, ws, connectionId) => { + try { + + // Decide internally which table to log to + const tableName = 'access_logs'; + + // Write log entry (log data can be specified via data.logData or any other object) + const result = await logger.write(data, tableName); + console.log('Log write result:', result); + + // Send response back to WebSocket client as needed + } catch (err) { + console.error('Error in TestAction:', err); + throw err; + } +}; +``` + +**Note**: +- If the logger service is offline (`online: false`), the `write()` function returns `{ success: false, error: 'Logger is inactive' }`. +- Columns in `logData` must match the table schema. Values are dynamically inserted into placeholders to prevent SQL injection. Keys not present in the table will be ignored or cause an error depending on DB configuration. +- Any log type (access, error, event, custom) can be handled with the same `write()` function. The table name determines the type. + + +#### Read Logs +```js +const loggerRead = require('./services/logger/readLogs.js'); // from the ROOT-Directory of the service + +// 1. Get all logs from a table +const allLogs = await loggerRead.getAll('access_logs'); +console.log(allLogs); + +// 2. Get filtered logs from a table +const filteredLogs = await loggerRead.get('access_logs', { user: 'user', action: 'login' }); +console.log(filteredLogs); +``` + +--- + +## Authentication + +The authentication service handles user registration, login, account updates, and email-based account activation.

Durch eine implementierte Sicherheitsebene mittels [JWT](https://www.npmjs.com/package/jsonwebtoken) sowie weiterer sicherheitsrelevanter Mechanismen wird sichergestellt, dass ausschließlich **L0** Zugriff auf diesen Layer erhält. + + +## Aufgaben und Verantwortlichkeiten +Da **L-1** der einzige Layer mit Zugriff auf die interne Datenbank ist, besteht die Aufgabe dieses Layers darin, die in der Datenbank gespeicherten Datensätze zu verwalten sowie deren Verarbeitung zu steuern. Die folgenden Aufgabenbereiche gehören dazu: +- Authentifizierung der Anfrage bzw. des Anfragenstellers +- Verarbeitungsschritte nach Authentifizierung: + - Überprüfung der empfangenen Datensätze auf Fehler + - Abgleich der gelieferten Daten mit der Datenbank + - Senden bzw. Schreiben von angefragten oder gelieferten Daten + + +## Kommunikation und Zugriffskontrolle +**L-1** wird ausschließlich von **L0** über eine interne WebSocket-Verbindung angesprochen, welcher auf `127.0.0.1` lauscht. Dadurch wird sichergestellt, dass kein externer Zugriff direkt auf die Datenbank erfolgen kann. Sämtliche Anfragen müssen den gesicherten Weg über **L0** durchlaufen, wo diese vorab authentifiziert und validiert werden. + +Die Kommunikation erfolgt nach einem Request-/Response-Prinzip, wobei **L-1** ausschließlich *reaktiv* arbeitet und keine eigenen Anfragen initiiert. + + +## Datenverarbeitung +Die Datenverarbeitung in **L-1** erfolgt strikt nach einem definierten Ablauf. Jede eingehende Anfrage wird zunächst auf Gültigkeit geprüft und anschließend entsprechend ihres Typs verarbeitet. Dabei wird zwischen Lese-, Schreib- und Löschoperationen (*CRUD*; Create, Read, Update, Delete) unterschieden. + +Nach erfolgreicher Authentifizierung und Validierung werden die angeforderten Operationen auf der Datenbank ausgeführt. Anschließend wird eine entsprechende Antwort generiert und an **L0** zurückgesendet, welcher die Antwort dann an den jeweiligen Client weiterleitet. Dieser strukturierte Ablauf stellt sicher, dass all Datenoperationen kontrolliert und nachvollziehbar durchgeführt werden. + + +## Datenintegrität und Validierung +**L-1** stellt sicher, dass alle verarbeiteten Daten konsistent und fehlerfrei bleiben. Eingehende Datensätze werden vor der Verarbeitung auf Struktur, Vollständigkeit und mögliche Fehler überprüft. + +Durch den Abgleich mit bestehenden Daten in der Datenbank wird verhindert, dass inkonsistente oder widersprüchliche Informationen gespeichert oder ausgegeben werden. Diese Validierungsmechanismen gewährleisten die Integrität der gesamten Datenbasis innerhalb des Systems. + + +## Fehlerbehandlung +Tritt während der Verarbeitung einer Anfrage ein Fehler auf, wird dieser von **L-1** erkannt und entsprechend behandelt. Ungültige oder fehlerhafte Anfragen werden nicht verarbeitet, sondern mit einer passenden Fehlermeldung beantwortet. + +Dabei wird sichergestellt, dass keine inkonsistenten Zustände in der Datenbank entstehen. Fehler werden zudem intern erfasst, um eine spätere Analyse und Optimierung des Systems zu ermöglichen. + + +## Module +**L-1** ist in mehrere Module unterteilt, die jeweils spezifische Aufgaben innerhalb der Datenverarbeitung übernehmen: +- **Service-Manager-Modul** — Koordination der internen Module → [Mehr](./modules/service-manager.md) +- **WebSocket-Modul** — Interne sichere WebSocket-Kommunikation → [Mehr](./modules/websocket-service.md) +- **DB-Service-Modul** — Datenbank-Manager und Pools → [Mehr](./modules/database-service.md) +- **Auth-Modul** — Anfrageauthentifizierung → [Mehr](./modules/auth-service.md) +- **Validierungsmodul** — Datenstruktur- und Konsistenzprüfung → [Mehr](./modules/validate-service.md) +- **Datenverarbeitungsmodul** — Datenbank-Operations-Manager → [Mehr](./modules/operations-manager.md) +- **Loggingmodul** — Systemereignisse und Fehler protokollieren → [Mehr](./modules/logging-service.md) \ No newline at end of file diff --git a/.backup/index.js b/.backup/index.js new file mode 100644 index 0000000..27d09de --- /dev/null +++ b/.backup/index.js @@ -0,0 +1,24 @@ +/* + ! /index.js + = Central Project Entry-Point +*/ + +// % import node & npm modules +import path from 'path';

Messages + * containing a `NODE_` prefix in the `cmd` property are reserved for use within + * Node.js core and will not be emitted in the child's `'message'` event. Rather, such messages are emitted using the `'internalMessage'` event and are consumed internally by Node.js. + * Applications should avoid using such messages or listening for `'internalMessage'` events as it is subject to change without notice. + * + * The optional `sendHandle` argument that may be passed to `subprocess.send()` is + * for passing a TCP server or socket object to the child process. The child will + * receive the object as the second argument passed to the callback function + * registered on the `'message'` event. Any data that is received and buffered in + * the socket will not be sent to the child. Sending IPC sockets is not supported on Windows. + * + * The optional `callback` is a function that is invoked after the message is + * sent but before the child may have received it. The function is called with a + * single argument: `null` on success, or an `Error` object on failure. + * + * If no `callback` function is provided and the message cannot be sent, an `'error'` event will be emitted by the `ChildProcess` object. This can + * happen, for instance, when the child process has already exited. + * + * `subprocess.send()` will return `false` if the channel has closed or when the + * backlog of unsent messages exceeds a threshold that makes it unwise to send + * more. Otherwise, the method returns `true`. The `callback` function can be + * used to implement flow control. + * + * #### Example: sending a server object + * + * The `sendHandle` argument can be used, for instance, to pass the handle of + * a TCP server object to the child process as illustrated in the example below: + * + * ```js + * import { createServer } from 'node:net'; + * import { fork } from 'node:child_process'; + * const subprocess = fork('subprocess.js'); + * + * // Open up the server object and send the handle. + * const server = createServer(); + * server.on('connection', (socket) => { + * socket.end('handled by parent'); + * }); + * server.listen(1337, () => { + * subprocess.send('server', server); + * }); + * ``` + * + * The child would then receive the server object as: + * + * ```js + * process.on('message', (m, server) => { + * if (m === 'server') { + * server.on('connection', (socket) => { + * socket.end('handled by child'); + * }); + * } + * }); + * ``` + * + * Once the server is now shared between the parent and child, some connections + * can be handled by the parent and some by the child. + * + * While the example above uses a server created using the `node:net` module, `node:dgram` module servers use exactly the same workflow with the exceptions of + * listening on a `'message'` event instead of `'connection'` and using `server.bind()` instead of `server.listen()`. This is, however, only + * supported on Unix platforms. + * + * #### Example: sending a socket object + * + * Similarly, the `sendHandler` argument can be used to pass the handle of a + * socket to the child process. The example below spawns two children that each + * handle connections with "normal" or "special" priority: + * + * ```js + * import { createServer } from 'node:net'; + * import { fork } from 'node:child_process'; + * const normal = fork('subprocess.js', ['normal']); + * const special = fork('subprocess.js', ['special']); + * + * // Open up the server and send sockets to child. Use pauseOnConnect to prevent + * // the sockets from being read before they are sent to the child process. + * const server = createServer({ pauseOnConnect: true }); + * server.on('connection', (socket) => { + * + * // If this is special priority... + * if (socket.remoteAddress === '74.125.127.100') { + * special.send('socket', socket); + * return; + * } + * // This is normal priority. + * normal.send('socket', socket); + * }); + * server.listen(1337); + * ``` + * + * The `subprocess.js` would receive the socket handle as the second argument + * passed to the event callback function: + * + * ```js + * process.on('message', (m, socket) => { + * if (m === 'socket') { + * if (socket) { + * // Check that the client socket exists. + * // It is possible for the socket to be closed between the time it is + * // sent and the time it is received in the child process. + * socket.end(`Request handled with ${process.argv[2]} priority`); + * } + * } + * }); + * ``` + * + * Do not use `.maxConnections` on a socket that has been passed to a subprocess. + * The parent cannot track when the socket is destroyed. + * + * Any `'message'` handlers in the subprocess should verify that `socket` exists, + * as the connection may have been closed during the time it takes to send the + * connection to the child. + * @since v0.5.9 + * @param sendHandle `undefined`, or a [`net.Socket`](https://nodejs.org/docs/latest-v26.x/api/net.html#class-netsocket), [`net.Server`](https://nodejs.org/docs/latest-v26.x/api/net.html#class-netserver), or [`dgram.Socket`](https://nodejs.org/docs/latest-v26.x/api/dgram.html#class-dgramsocket) object. + * @param options The `options` argument, if present, is an object used to parameterize the sending of certain types of handles. `options` supports the following properties: + */ + send(message: Serializable, callback?: (error: Error | null) => void): boolean; + send(message: Serializable, sendHandle?: SendHandle, callback?: (error: Error | null) => void): boolean; + send( + message: Serializable, + sendHandle?: SendHandle, + options?: MessageOptions, + callback?: (error: Error | null) => void, + ): boolean; + /** + * Closes the IPC channel between parent and child, allowing the child to exit + * gracefully once there are no other connections keeping it alive.

It runs the server tests that are aided by +the usage of `engine.io-client`. + +Make sure `npm install` is run first. + +## Goals + +The main goal of `Engine` is ensuring the most reliable realtime communication. +Unlike the previous Socket.IO core, it always establishes a long-polling +connection first, then tries to upgrade to better transports that are "tested" on +the side. + +During the lifetime of the Socket.IO projects, we've found countless drawbacks +to relying on `HTML5 WebSocket` or `Flash Socket` as the first connection +mechanisms. + +Both are clearly the _right way_ of establishing a bidirectional communication, +with HTML5 WebSocket being the way of the future. However, to answer most business +needs, alternative traditional HTTP 1.1 mechanisms are just as good as delivering +the same solution. + +WebSocket based connections have two fundamental benefits: + +1. **Better server performance** + - _A: Load balancers_
+ Load balancing a long polling connection poses a serious architectural nightmare + since requests can come from any number of open sockets by the user agent, but + they all need to be routed to the process and computer that owns the `Engine` + connection. This negatively impacts RAM and CPU usage. + - _B: Network traffic_
+ WebSocket is designed around the premise that each message frame has to be + surrounded by the least amount of data. In HTTP 1.1 transports, each message + frame is surrounded by HTTP headers and chunked encoding frames. If you try to + send the message _"Hello world"_ with xhr-polling, the message ultimately + becomes larger than if you were to send it with WebSocket. + - _C: Lightweight parser_
+ As an effect of **B**, the server has to do a lot more work to parse the network + data and figure out the message when traditional HTTP requests are used + (as in long polling). This means that another advantage of WebSocket is + less server CPU usage. + +2. **Better user experience** + + Due to the reasons stated in point **1**, the most important effect of being able + to establish a WebSocket connection is raw data transfer speed, which translates + in _some_ cases in better user experience. + + Applications with heavy realtime interaction (such as games) will benefit greatly, + whereas applications like realtime chat (Gmail/Facebook), newsfeeds (Facebook) or + timelines (Twitter) will have negligible user experience improvements. + +Having said this, attempting to establish a WebSocket connection directly so far has +proven problematic: + +1. **Proxies**
+ Many corporate proxies block WebSocket traffic. + +2. **Personal firewall and antivirus software**
+ As a result of our research, we've found that at least 3 personal security + applications block WebSocket traffic. + +3. **Cloud application platforms**
+ Platforms like Heroku or No.de have had trouble keeping up with the fast-paced + nature of the evolution of the WebSocket protocol. Applications therefore end up + inevitably using long polling, but the seamless installation experience of + Socket.IO we strive for (_"require() it and it just works"_) disappears. + +Some of these problems have solutions. In the case of proxies and personal programs, +however, the solutions many times involve upgrading software. Experience has shown +that relying on client software upgrades to deliver a business solution is +fruitless: the very existence of this project has to do with a fragmented panorama +of user agent distribution, with clients connecting with latest versions of the most +modern user agents (Chrome, Firefox and Safari), but others with versions as low as +IE 5.5. + +From the user perspective, an unsuccessful WebSocket connection can translate in +up to at least 10 seconds of waiting for the realtime application to begin +exchanging data. This **perceptively** hurts user experience. + +To summarize, **Engine** focuses on reliability and user experience first, marginal +potential UX improvements and increased server performance second. `Engine` is the +result of all the lessons learned with WebSocket in the wild. + +## Architecture + +The main premise of `Engine`, and the core of its existence, is the ability to +swap transports on the fly. A connection starts as xhr-polling, but it can +switch to WebSocket. + +The central problem this poses is: how do we switch transports without losing +messages? + +`Engine` only switches from polling to another transport in between polling +cycles. Since the server closes the connection after a certain timeout when +there's no activity, and the polling transport implementation buffers messages +in between connections, this ensures no message loss and optimal performance. + +Another benefit of this design is that we workaround almost all the limitations +of **Flash Socket**, such as slow connection times, increased file size (we can +safely lazy load it without hurting user experience), etc. + +## FAQ + +### Can I use engine without Socket.IO ? + +Absolutely. Although the recommended framework for building realtime applications +is Socket.IO, since it provides fundamental features for real-world applications +such as multiplexing, reconnection support, etc. + +`Engine` is to Socket.IO what Connect is to Express. An essential piece for building +realtime frameworks, but something you _probably_ won't be using for building +actual applications. + +### Does the server serve the client? + +No. The main reason is that `Engine` is meant to be bundled with frameworks. +Socket.IO includes `Engine`, therefore serving two clients is not necessary.

May contain cycles (handled by the cycle detector). Deeply-nested non-cyclic input surfaces as a catchable synchronous `RangeError` (stack overflow), not unbounded resource consumption; callers that serialize externally-influenced objects should bound their depth/size beforehand. +- **Options:** Provided by the caller +- **Cycle Tracking:** Used only during stringification to detect and handle circular references + +### 4.

Mitigation/Countermeasures + +| Threat Identified | Proposed Mitigation | +|---------------------------------------------------|---------------------| +| Tampering (malicious input, prototype pollution) | Strict input validation; keep `allowPrototypes: false` by default; use `plainObjects` for output; ensure builtins/globals are never modified by parse[4][8]. | +| Information Disclosure (error messages) | Generic error messages without stack traces or internal paths. | +| Denial of Service (memory/CPU exhaustion) | `arrayLimit`, `parameterLimit`, and depth limiting apply with safe defaults. Note that `arrayLimit` is a representation threshold (array vs. object), and `parameterLimit` bounds only the number of `&`-delimited parameters - neither caps the elements produced by `comma: true` splitting. For a hard cap that rejects oversized untrusted input, opt in to `throwOnLimitExceeded: true` (default `false`), and always bound input size at the transport layer[7]. On the `stringify` side, the input is the caller's own object rather than an untrusted string, so unbounded nesting manifests as a catchable `RangeError` (stack overflow) rather than exhaustion; callers serializing externally-influenced objects should bound depth/size beforehand, and may opt into `stringify`'s `depth` option (default `Infinity`) for a deterministic, catchable error. | +| Elevation of Privilege (prototype pollution) | Keep `allowPrototypes: false`; validate options against allowlist; use `plainObjects` to avoid prototype pollution[4][8]. | + +### 7. Risk Ranking + +- **High:** Denial of Service via array parsing or malformed input (historical vulnerability) +- **Medium:** Prototype pollution via options or input (if `allowPrototypes` enabled) +- **Low:** Information disclosure in errors + +### 8. Next Steps & Review + +1. **Audit option validation logic.** +2. **Depth limiting:** `parse` enforces a `depth` bound by default (with `strictDepth` to throw); `stringify` offers an opt-in `depth` bound (default `Infinity`, since its input is caller-produced) for defense-in-depth. +3. **Implement fuzz testing for parser and stringifier edge cases.** +4. **Regularly review dependencies for vulnerabilities.** +5. **Keep documentation and threat model up to date.** +6. **Ensure builtins/globals are never modified as a result of parse.** +7. **Support round-trip consistency between parse

The strictDepth option adds a layer of protection by throwing an error when the limit is exceeded, allowing you to catch and handle such cases. + +For similar reasons, by default **qs** will only parse up to 1000 parameters. This can be overridden by passing a `parameterLimit` option: + +```javascript +var limited = qs.parse('a=b&c=d', { parameterLimit: 1 }); +assert.deepEqual(limited, { a: 'b' }); +``` + +If you want an error to be thrown whenever the a limit is exceeded (eg, `parameterLimit`, `arrayLimit`), set the `throwOnLimitExceeded` option to `true`. This option will generate a descriptive error if the query string exceeds a configured limit. +```javascript +try { + qs.parse('a=1&b=2&c=3&d=4', { parameterLimit: 3, throwOnLimitExceeded: true }); +} catch (err) { + assert(err instanceof Error); + assert.strictEqual(err.message, 'Parameter limit exceeded. Only 3 parameters allowed.'); +} +``` + +When `throwOnLimitExceeded` is set to `false` (default), **qs** will parse up to the specified `parameterLimit` and ignore the rest without throwing an error. + +Note that `parameterLimit` only bounds the number of `&`-delimited parameters; it does not limit how many values a single parameter expands into. In particular, when `comma: true` is enabled, a single parameter's value is split on commas into arbitrarily many elements, which `parameterLimit` does not constrain. To bound the total element count from untrusted input, set `throwOnLimitExceeded: true` (see `arrayLimit` below), and always bound the input size at the transport layer (e.g. an HTTP body-size limit). + +To bypass the leading question mark, use `ignoreQueryPrefix`: + +```javascript +var prefixed = qs.parse('?a=b&c=d', { ignoreQueryPrefix: true }); +assert.deepEqual(prefixed, { a: 'b', c: 'd' }); +``` + +An optional delimiter can also be passed: + +```javascript +var delimited = qs.parse('a=b;c=d', { delimiter: ';' }); +assert.deepEqual(delimited, { a: 'b', c: 'd' }); +``` + +Delimiters can be a regular expression too: + +```javascript +var regexed = qs.parse('a=b;c=d,e=f', { delimiter: /[;,]/ }); +assert.deepEqual(regexed, { a: 'b', c: 'd', e: 'f' }); +``` + +Option `allowDots` can be used to enable dot notation: + +```javascript +var withDots = qs.parse('a.b=c', { allowDots: true }); +assert.deepEqual(withDots, { a: { b: 'c' } }); +``` + +Option `decodeDotInKeys` can be used to decode dots in keys +Note: it implies `allowDots`, so `parse` will error if you set `decodeDotInKeys` to `true`, and `allowDots` to `false`. + +```javascript +var withDots = qs.parse('name%252Eobj.first=John&name%252Eobj.last=Doe', { decodeDotInKeys: true }); +assert.deepEqual(withDots, { 'name.obj': { first: 'John', last: 'Doe' }}); +``` + +Option `allowEmptyArrays` can be used to allow empty array values in an object +```javascript +var withEmptyArrays = qs.parse('foo[]&bar=baz', { allowEmptyArrays: true }); +assert.deepEqual(withEmptyArrays, { foo: [], bar: 'baz' }); +``` + +Option `duplicates` can be used to change the behavior when duplicate keys are encountered +```javascript +assert.deepEqual(qs.parse('foo=bar&foo=baz'), { foo: ['bar', 'baz'] }); +assert.deepEqual(qs.parse('foo=bar&foo=baz', { duplicates: 'combine' }), { foo: ['bar', 'baz'] }); +assert.deepEqual(qs.parse('foo=bar&foo=baz', { duplicates: 'first' }), { foo: 'bar' }); +assert.deepEqual(qs.parse('foo=bar&foo=baz', { duplicates: 'last' }), { foo: 'baz' }); +``` + +Note that keys with bracket notation (`[]`) always combine into arrays, regardless of the `duplicates` setting: +```javascript +assert.deepEqual(qs.parse('a=1&a=2&b[]=1&b[]=2', { duplicates: 'last' }), { a: '2', b: ['1', '2'] }); +``` + +If you have to deal with legacy browsers or services, there's also support for decoding percent-encoded octets as iso-8859-1: + +```javascript +var oldCharset = qs.parse('a=%A7', { charset: 'iso-8859-1' }); +assert.deepEqual(oldCharset, { a: '§' }); +``` + +Some services add an initial `utf8=✓` value to forms so that old Internet Explorer versions are more likely to submit the form as utf-8. +Additionally, the server can check the value against wrong encodings of the checkmark character and detect that a query string or `application/x-www-form-urlencoded` body was *not* sent as utf-8, eg. if the form had an `accept-charset` parameter or the containing page had a different character set. + +**qs** supports this mechanism via the `charsetSentinel` option. +If specified, the `utf8` parameter will be omitted from the returned object. +It will be used to switch to `iso-8859-1`/`utf-8` mode depending on how the checkmark is encoded. + +**Important**: When you specify both the `charset` option and the `charsetSentinel` option, the `charset` will be overridden when the request contains a `utf8` parameter from which the actual charset can be deduced. +In that sense the `charset` will behave as the default charset rather than the authoritative charset. + +```javascript +var detectedAsUtf8 = qs.parse('utf8=%E2%9C%93&a=%C3%B8', { + charset: 'iso-8859-1', + charsetSentinel: true +}); +assert.deepEqual(detectedAsUtf8, { a: 'ø' }); + +// Browsers encode the checkmark as ✓ when submitting as iso-8859-1: +var detectedAsIso8859_1 = qs.parse('utf8=%26%2310003%3B&a=%F8', { + charset: 'utf-8', + charsetSentinel: true +}); +assert.deepEqual(detectedAsIso8859_1, { a: 'ø' }); +``` + +If you want to decode the `&#...;` syntax to the actual character, you can specify the `interpretNumericEntities` option as well: + +```javascript +var detectedAsIso8859_1 = qs.parse('a=%26%239786%3B', { + charset: 'iso-8859-1', + interpretNumericEntities: true +}); +assert.deepEqual(detectedAsIso8859_1, { a: '☺' }); +``` + +It also works when the charset has been detected in `charsetSentinel` mode. + +### Parsing Arrays + +**qs** can also parse arrays using a similar `[]` notation: + +```javascript +var withArray = qs.parse('a[]=b&a[]=c'); +assert.deepEqual(withArray, { a: ['b', 'c'] }); +``` + +You may specify an index as well: + +```javascript +var withIndexes = qs.parse('a[1]=c&a[0]=b'); +assert.deepEqual(withIndexes, { a: ['b', 'c'] }); +``` + +Note that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number to create an array. +When creating arrays with specific indices, **qs** will compact a sparse array to only the existing values preserving their order: + +```javascript +var noSparse = qs.parse('a[1]=b&a[15]=c'); +assert.deepEqual(noSparse, { a: ['b', 'c'] }); +``` + +You may also use `allowSparse` option to parse sparse arrays: + +```javascript +var sparseArray = qs.parse('a[1]=2&a[3]=5', { allowSparse: true }); +assert.deepEqual(sparseArray, { a: [, '2', , '5'] }); +``` + +Note that an empty string is also a value, and will be preserved: + +```javascript +var withEmptyString = qs.parse('a[]=&a[]=b'); +assert.deepEqual(withEmptyString, { a: ['', 'b'] }); + +var withIndexedEmptyString = qs.parse('a[0]=b&a[1]=&a[2]=c'); +assert.deepEqual(withIndexedEmptyString, { a: ['b', '', 'c'] }); +``` + +**qs** will also limit arrays to a maximum of `20` elements. +Any array members with an index of `20` or greater will instead be converted to an object with the index as the key. +This is needed to handle cases when someone sent, for example, `a[999999999]` and it will take significant time to iterate over this huge array. + +```javascript +var withMaxIndex = qs.parse('a[100]=b'); +assert.deepEqual(withMaxIndex, { a: { '100': 'b' } }); +``` + +This limit can be overridden by passing an `arrayLimit` option: + +```javascript +var withArrayLimit = qs.parse('a[1]=b', { arrayLimit: 0 }); +assert.deepEqual(withArrayLimit, { a: { '1': 'b' } }); +``` + +If you want to throw an error whenever the array limit is exceeded, set the `throwOnLimitExceeded` option to `true`. This option will generate a descriptive error if the query string exceeds a configured limit. +```javascript +try { + qs.parse('a[1]=b', { arrayLimit: 0, throwOnLimitExceeded: true }); +} catch (err) { + assert(err instanceof Error); + assert.strictEqual(err.message, 'Array limit exceeded. Only 0 elements allowed in an array.'); +} +``` + +When `throwOnLimitExceeded` is set to `false` (default), **qs** will parse up to the specified `arrayLimit` and if the limit is exceeded, the array will instead be converted to an object with the index as the key. + +Note that `arrayLimit` is a *representation* threshold that controls when a numerically-indexed collection switches from an array to an object — it is **not** a hard cap on the total number of elements parsed. With the default `throwOnLimitExceeded: false`, exceeding `arrayLimit` never rejects or truncates input; it only changes the container type, and the resulting object still holds every element (so its size stays proportional to the input). This conversion is itself a safeguard: it avoids allocating a huge sparse array for input like `a[999999999]`. If you need a hard limit that rejects oversized input from untrusted sources, set `throwOnLimitExceeded: true`. + +To prevent array syntax (`a[]`, `a[0]`) from being parsed as arrays, set `parseArrays` to `false`. +Note that duplicate keys (e.g. `a=b&a=c`) may still produce arrays when `duplicates` is `'combine'` (the default). + +```javascript +var noParsingArrays = qs.parse('a[]=b', { parseArrays: false }); +assert.deepEqual(noParsingArrays, { a: { '0': 'b' } }); +``` + +If you mix notations, **qs** will merge the two items into an object: + +```javascript +var mixedNotation = qs.parse('a[0]=b&a[b]=c'); +assert.deepEqual(mixedNotation, { a: { '0': 'b', b: 'c' } }); +``` + +When a key appears as both a plain value and an object, **qs** will by default wrap the conflicting values in an array (`strictMerge` defaults to `true`): + +```javascript +assert.deepEqual(qs.parse('a[b]=c&a=d'), { a: [{ b: 'c' }, 'd'] }); +assert.deepEqual(qs.parse('a=d&a[b]=c'), { a: ['d', { b: 'c' }] }); +``` + +To restore the legacy behavior (where the primitive is used as a key with value `true`), set `strictMerge` to `false`: + +```javascript +assert.deepEqual(qs.parse('a[b]=c&a=d', { strictMerge: false }), { a: { b: 'c', d: true } }); +``` + +You can also create arrays of objects: + +```javascript +var arraysOfObjects = qs.parse('a[][b]=c'); +assert.deepEqual(arraysOfObjects, { a: [{ b: 'c' }] }); +``` + +Some people use comma to join array, **qs** can parse it: +```javascript +var arraysOfObjects = qs.parse('a=b,c', { comma: true }) +assert.deepEqual(arraysOfObjects, { a: ['b', 'c'] }) +``` +(_this cannot convert nested objects, such as `a={b:1},{c:d}`_) + +### Parsing primitive/scalar values (numbers, booleans, null, etc) + +By default, all values are parsed as strings. +This behavior will not change and is explained in [issue #91](https://github.com/ljharb/qs/issues/91). + +```javascript +var primitiveValues = qs.parse('a=15&b=true&c=null'); +assert.deepEqual(primitiveValues, { a: '15', b: 'true', c: 'null' }); +``` + +If you wish to auto-convert values which look like numbers, booleans, and other values into their primitive counterparts, you can use the [query-types Express JS middleware](https://github.com/xpepermint/query-types) which will auto-convert all request query parameters. + +### Stringifying + +[](#preventEval) +```javascript +qs.stringify(object, [options]); +``` + +When stringifying, **qs** by default URI encodes output. Objects are stringified as you would expect: + +```javascript +assert.equal(qs.stringify({ a: 'b' }), 'a=b'); +assert.equal(qs.stringify({ a: { b: 'c' } }), 'a%5Bb%5D=c'); +``` + +This encoding can be disabled by setting the `encode` option to `false`: + +```javascript +var unencoded = qs.stringify({ a: { b: 'c' } }, { encode: false }); +assert.equal(unencoded, 'a[b]=c'); +``` + +Encoding can be disabled for keys by setting the `encodeValuesOnly` option to `true`: +```javascript +var encodedValues = qs.stringify( + { a: 'b', c: ['d', 'e=f'], f: [['g'], ['h']] }, + { encodeValuesOnly: true } +); +assert.equal(encodedValues,'a=b&c[0]=d&c[1]=e%3Df&f[0][0]=g&f[1][0]=h'); +``` + +This encoding can also be replaced by a custom encoding method set as `encoder` option: + +```javascript +var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str) { + // Passed in values `a`, `b`, `c` + return // Return encoded string +}}) +``` + +_(Note: the `encoder` option does not apply if `encode` is `false`)_ + +By default, `qs.stringify` serializes an object of any nesting depth. +For backwards compatibility, and because its input is the caller's own object rather than a query string parsed by **qs**, this is unbounded. +If you serialize objects whose nesting can be influenced by untrusted input, bound it with the numeric `depth` option (default `Infinity`); +exceeding it throws a catchable `RangeError` instead of eventually overflowing the call stack: + +```javascript +try { + qs.stringify({ a: { b: { c: { d: 'e' } } } }, { depth: 2 }); +} catch (err) { + assert(err instanceof RangeError); + assert.strictEqual(err.message, 'Input depth exceeded depth option of 2'); +} +``` + +Analogue to the `encoder` there is a `decoder` option for `parse` to override decoding of properties and values: + +```javascript +var decoded = qs.parse('x=z', { decoder: function (str) { + // Passed in values `x`, `z` + return // Return decoded string +}}) +``` + +You can encode keys and values using different logic by using the type argument provided to the encoder: + +```javascript +var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str, defaultEncoder, charset, type) { + if (type === 'key') { + return // Encoded key + } else if (type === 'value') { + return // Encoded value + } +}}) +``` + +The type argument is also provided to the decoder: + +```javascript +var decoded = qs.parse('x=z', { decoder: function (str, defaultDecoder, charset, type) { + if (type === 'key') { + return // Decoded key + } else if (type === 'value') { + return // Decoded value + } +}}) +``` + +Examples beyond this point will be shown as though the output is not URI encoded for clarity. +Please note that the return values in these cases *will* be URI encoded during real usage. + +When arrays are stringified, they follow the `arrayFormat` option, which defaults to `indices`: + +```javascript +qs.stringify({ a: ['b', 'c', 'd'] }); +// 'a[0]=b&a[1]=c&a[2]=d' +``` + +You may override this by setting the `indices` option to `false`, or to be more explicit, the `arrayFormat` option to `repeat`: + +```javascript +qs.stringify({ a: ['b', 'c', 'd'] }, { indices: false }); +// 'a=b&a=c&a=d' +``` + +You may use the `arrayFormat` option to specify the format of the output array: + +```javascript +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'indices' }) +// 'a[0]=b&a[1]=c' +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'brackets' }) +// 'a[]=b&a[]=c' +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'repeat' }) +// 'a=b&a=c' +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'comma' }) +// 'a=b,c' +``` + +Note: when using `arrayFormat` set to `'comma'`, you can also pass the `commaRoundTrip` option set to `true` or `false`, to append `[]` on single-item arrays, so that they can round trip through a parse. + +When objects are stringified, by default they use bracket notation: + +```javascript +qs.stringify({ a: { b: { c: 'd', e: 'f' } } }); +// 'a[b][c]=d&a[b][e]=f' +``` + +You may override this to use dot notation by setting the `allowDots` option to `true`: + +```javascript +qs.stringify({ a: { b: { c: 'd', e: 'f' } } }, { allowDots: true }); +// 'a.b.c=d&a.b.e=f' +``` + +You may encode the dot notation in the keys of object with option `encodeDotInKeys` by setting it to `true`: +Note: it implies `allowDots`, so `stringify` will error if you set `decodeDotInKeys` to `true`, and `allowDots` to `false`. +Caveat: when `encodeValuesOnly` is `true` as well as `encodeDotInKeys`, only dots in keys and nothing else will be encoded. +```javascript +qs.stringify({ "name.obj": { "first": "John", "last": "Doe" } }, { allowDots: true, encodeDotInKeys: true }) +// 'name%252Eobj.first=John&name%252Eobj.last=Doe' +``` + +You may allow empty array values by setting the `allowEmptyArrays` option to `true`: +```javascript +qs.stringify({ foo: [], bar: 'baz' }, { allowEmptyArrays: true }); +// 'foo[]&bar=baz' +``` + +Empty strings and null values will omit the value, but the equals sign (=) remains in place: + +```javascript +assert.equal(qs.stringify({ a: '' }), 'a='); +``` + +Key with no values (such as an empty object or array) will return nothing: + +```javascript +assert.equal(qs.stringify({ a: [] }), ''); +assert.equal(qs.stringify({ a: {} }), ''); +assert.equal(qs.stringify({ a: [{}] }), ''); +assert.equal(qs.stringify({ a: { b: []} }), ''); +assert.equal(qs.stringify({ a: { b: {}} }), ''); +``` + +Properties that are set to `undefined` will be omitted entirely: + +```javascript +assert.equal(qs.stringify({ a: null, b: undefined }), 'a='); +``` + +The query string may optionally be prepended with a question mark: + +```javascript +assert.equal(qs.stringify({ a: 'b', c: 'd' }, { addQueryPrefix: true }), '?a=b&c=d'); +``` + +Note that when the output is an empty string, the prefix will not be added: + +```javascript +assert.equal(qs.stringify({}, { addQueryPrefix: true }), ''); +``` + +The delimiter may be overridden with stringify as well: + +```javascript +assert.equal(qs.stringify({ a: 'b', c: 'd' }, { delimiter: ';' }), 'a=b;c=d'); +``` + +If you only want to override the serialization of `Date` objects, you can provide a `serializeDate` option: + +```javascript +var date = new Date(7); +assert.equal(qs.stringify({ a: date }), 'a=1970-01-01T00:00:00.007Z'.replace(/:/g, '%3A')); +assert.equal( + qs.stringify({ a: date }, { serializeDate: function (d) { return d.getTime(); } }), + 'a=7' +); +``` + +You may use the `sort` option to affect the order of parameter keys: + +```javascript +function alphabeticalSort(a, b) { + return a.localeCompare(b); +} +assert.equal(qs.stringify({ a: 'c', z: 'y', b : 'f' }, { sort: alphabeticalSort }), 'a=c&b=f&z=y'); +``` + +Finally, you can use the `filter` option to restrict which keys will be included in the stringified output. +If you pass a function, it will be called for each key to obtain the replacement value. +Otherwise, if you pass an array, it will be used to select properties and array indices for stringification: + +```javascript +function filterFunc(prefix, value) { + if (prefix == 'b') { + // Return an `undefined` value to omit a property. + return; + } + if (prefix == 'e[f]') { + return value.getTime(); + } + if (prefix == 'e[g][0]') { + return value * 2; + } + return value; +} +qs.stringify({ a: 'b', c: 'd', e: { f: new Date(123), g: [2] } }, { filter: filterFunc }); +// 'a=b&c=d&e[f]=123&e[g][0]=4' +qs.stringify({ a: 'b', c: 'd', e: 'f' }, { filter: ['a', 'e'] }); +// 'a=b&e=f' +qs.stringify({ a: ['b', 'c', 'd'], e: 'f' }, { filter: ['a', 0, 2] }); +// 'a[0]=b&a[2]=d' +``` + +You could also use `filter` to inject custom serialization for user defined types. +Consider you're working with some api that expects query strings of the format for ranges: + +``` +https://domain.com/endpoint?range=30...70 +``` + +For which you model as: + +```javascript +class Range { + constructor(from, to) { + this.from = from; + this.to = to; + } +} +``` + +You could _inject_ a custom serializer to handle values of this type: + +```javascript +qs.stringify( + { + range: new Range(30, 70), + }, + { + filter: (prefix, value) => { + if (value instanceof Range) { + return `${value.from}...${value.to}`; + } + // serialize the usual way + return value; + }, + } +); +// range=30...70 +``` + +### Handling of `null` values + +By default, `null` values are treated like empty strings: + +```javascript +var withNull = qs.stringify({ a: null, b: '' }); +assert.equal(withNull, 'a=&b='); +``` + +Parsing does not distinguish between parameters with and without equal signs. +Both are converted to empty strings. + +```javascript +var equalsInsensitive = qs.parse('a&b='); +assert.deepEqual(equalsInsensitive, { a: '', b: '' }); +``` + +To distinguish between `null` values and empty strings use the `strictNullHandling` flag. In the result string the `null` +values have no `=` sign: + +```javascript +var strictNull = qs.stringify({ a: null, b: '' }, { strictNullHandling: true }); +assert.equal(strictNull, 'a&b='); +``` + +To parse values without `=` back to `null` use the `strictNullHandling` flag: + +```javascript +var parsedStrictNull = qs.parse('a&b=', { strictNullHandling: true }); +assert.deepEqual(parsedStrictNull, { a: null, b: '' }); +``` + +To completely skip rendering keys with `null` values, use the `skipNulls` flag: + +```javascript +var nullsSkipped = qs.stringify({ a: 'b', c: null}, { skipNulls: true }); +assert.equal(nullsSkipped, 'a=b'); +``` + +If you're communicating with legacy systems, you can switch to `iso-8859-1` using the `charset` option: + +```javascript +var iso = qs.stringify({ æ: 'æ' }, { charset: 'iso-8859-1' }); +assert.equal(iso, '%E6=%E6'); +``` + +Characters that don't exist in `iso-8859-1` will be converted to numeric entities, similar to what browsers do: + +```javascript +var numeric = qs.stringify({ a: '☺' }, { charset: 'iso-8859-1' }); +assert.equal(numeric, 'a=%26%239786%3B'); +``` + +You can use the `charsetSentinel` option to announce the character by including an `utf8=✓` parameter with the proper encoding if the checkmark, similar to what Ruby on Rails and others do when submitting forms. + +```javascript +var sentinel = qs.stringify({ a: '☺' }, { charsetSentinel: true }); +assert.equal(sentinel, 'utf8=%E2%9C%93&a=%E2%98%BA'); + +var isoSentinel = qs.stringify({ a: 'æ' }, { charsetSentinel: true, charset: 'iso-8859-1' }); +assert.equal(isoSentinel, 'utf8=%26%2310003%3B&a=%E6'); +``` + +### Dealing with special character sets + +By default the encoding and decoding of characters is done in `utf-8`, and `iso-8859-1` support is also built in via the `charset` parameter. + +If you wish to encode querystrings to a different character set (i.e. +[Shift JIS](https://en.wikipedia.org/wiki/Shift_JIS)) you can use the +[`qs-iconv`](https://github.com/martinheidegger/qs-iconv) library: + +```javascript +var encoder = require('qs-iconv/encoder')('shift_jis'); +var shiftJISEncoded = qs.stringify({ a: 'こんにちは！' }, { encoder: encoder }); +assert.equal(shiftJISEncoded, 'a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I'); +``` + +This also works for decoding of query strings: + +```javascript +var decoder = require('qs-iconv/decoder')('shift_jis'); +var obj = qs.parse('a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I', { decoder: decoder }); +assert.deepEqual(obj, { a: 'こんにちは！' }); +``` + +### RFC 3986 and RFC 1738 space encoding + +RFC3986 used as default option and encodes ' ' to *%20* which is backward compatible. +In the same time, output can be stringified as per RFC1738 with ' ' equal to '+'. + +``` +assert.equal(qs.stringify({ a: 'b c' }), 'a=b%20c'); +assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC3986' }), 'a=b%20c'); +assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC1738' }), 'a=b+c'); +``` + +## Security + +Please email [@ljharb](https://github.com/ljharb) or see https://tidelift.com/security if you have a potential security vulnerability to report. + +## qs for enterprise + +Available as part of the Tidelift Subscription + +The maintainers of qs and thousands of other packages are working with Tidelift to deliver commercial support and maintenance for the open source dependencies you use to build your applications. +Save time, reduce risk, and improve code health, while paying the maintainers of the exact dependencies you use. +[Learn more.](https://tidelift.com/subscription/pkg/npm-qs?utm_source=npm-qs&utm_medium=referral&utm_campaign=enterprise&utm_term=repo) + +[package-url]: https://npmjs.org/package/qs +[npm-version-svg]: https://versionbadg.es/ljharb/qs.svg +[deps-svg]: https://david-dm.org/ljharb/qs.svg +[deps-url]: https://david-dm.org/ljharb/qs +[dev-deps-svg]: https://david-dm.org/ljharb/qs/dev-status.svg +[dev-deps-url]: https://david-dm.org/ljharb/qs#info=devDependencies +[npm-badge-png]: https://nodei.co/npm/qs.png?downloads=true&stars=true +[license-image]: https://img.shields.io/npm/l/qs.svg +[license-url]: LICENSE +[downloads-image]: https://img.shields.io/npm/dm/qs.svg +[downloads-url]: https://npm-stat.com/charts.html?package=qs +[codecov-image]: https://codecov.io/gh/ljharb/qs/branch/main/graphs/badge.svg +[codecov-url]: https://app.codecov.io/gh/ljharb/qs/ +[actions-image]: https://img.shields.io/github/check-runs/ljharb/qs/main +[actions-url]: https://github.com/ljharb/qs/actions + +## Acknowledgements + +qs logo by [NUMI](https://github.com/numi-hq/open-design): + +[NUMI Logo](https://numi.tech/?ref=qs) diff --git a/node_modules/qs/dist/qs.js b/node_modules/qs/dist/qs.js new file mode 100644 index 0000000..1419e8d --- /dev/null +++ b/node_modules/qs/dist/qs.js @@ -0,0 +1,141 @@ +(function(f){if(typeof exports==="object"&&typeof module!=="undefined"){module.exports=f()}else if(typeof define==="function"&&define.amd){define([],f)}else{var g;if(typeof window!=="undefined"){g=window}else if(typeof global!=="undefined"){g=global}else if(typeof self!=="undefined"){g=self}else{g=this}g.Qs = f()}})(function(){var define,module,exports;return (function(){function r(e,n,t){function o(i,f){if(!n[i]){if(!e[i]){var c="function"==typeof require&&require;if(!f&&c)return c(i,!0);if(u)return u(i,!0);var a=new Error("Cannot find module '"+i+"'");throw a.code="MODULE_NOT_FOUND",a}var p=n[i]={exports:{}};e[i][0].call(p.exports,function(r){var n=e[i][1][r];return o(n||r)},p,p.exports,r,e,n,t)}return n[i].exports}for(var u="function"==typeof require&&require,i=0;i-1){if(t.throwOnLimitExceeded)for(var i=0,a=e.indexOf(",");a>-1;){if((i+=1)>=t.arrayLimit)throw new RangeError("Array limit exceeded.

Calling `next('route')` bypasses the remaining +middleware and the handler mounted for this route, passing the request to the +next route suitable for handling this request. + +Route handlers and middleware can themselves use `next('router')` at any time +to exit the current router instance completely, invoking the top-level callback. + +### router.param(name, param_middleware) + +Maps the specified path parameter `name` to a specialized param-capturing middleware. + +This function positions the middleware in the same stack as `.use`. + +The function can optionally return a `Promise` object. If a `Promise` object +is returned from the function, the router will attach an `onRejected` callback +using `.then`. If the promise is rejected, `next` will be called with the +rejected value, or an error if the value is falsy. + +Parameter mapping is used to provide pre-conditions to routes +which use normalized placeholders. For example a _:user_id_ parameter +could automatically load a user's information from the database without +any additional code: + + + +```js +router.param('user_id', function (req, res, next, id) { + User.find(id, function (err, user) { + if (err) { + return next(err) + } else if (!user) { + return next(new Error('failed to load user')) + } + req.user = user + + // continue processing the request + next() + }) +}) +``` + +### router.route(path) + +Creates an instance of a single `Route` for the given `path`. +(See `Router.Route` below) + +Routes can be used to handle http `methods` with their own, optional middleware. + +Using `router.route(path)` is a recommended approach to avoiding duplicate +route naming and thus typo errors. + + + +```js +var api = router.route('/api/') +``` + +## Router.Route(path) + +Represents a single route as an instance that can be used to handle http +`methods` with it's own, optional middleware. + +### route\[method](handler) + +These are functions which you can directly call on a route to register a new +`handler` for the `method` on the route. + + + +```js +// handle a `GET` request +var status = router.route('/status') + +status.get(function (req, res) { + res.setHeader('Content-Type', 'text/plain; charset=utf-8') + res.end('All Systems Green!') +}) +``` + +### route.all(handler) + +Adds a handler for all HTTP methods to this route. + +The handler can behave like middleware and call `next` to continue processing +rather than responding. + + + +```js +router.route('/') + .all(function (req, res, next) { + next() + }) + .all(checkSomething) + .get(function (req, res) { + res.setHeader('Content-Type', 'text/plain; charset=utf-8') + res.end('Hello World!') + }) +``` + +## Middleware + +Middleware (and method handlers) are functions that follow specific function +parameters and have defined behavior when used with `router`. The most common +format is with three parameters - "req", "res" and "next". + +- `req` - This is a [HTTP incoming message](https://nodejs.org/api/http.html#http_http_incomingmessage) instance. +- `res` - This is a [HTTP server response](https://nodejs.org/api/http.html#http_class_http_serverresponse) instance. +- `next` - Calling this function that tells `router` to proceed to the next matching middleware or method handler. It accepts an error as the first argument. + +The function can optionally return a `Promise` object. If a `Promise` object +is returned from the function, the router will attach an `onRejected` callback +using `.then`. If the promise is rejected, `next` will be called with the +rejected value, or an error if the value is falsy. + +Middleware and method handlers can also be defined with four arguments. When +the function has four parameters defined, the first argument is an error and +subsequent arguments remain, becoming - "err", "req", "res", "next". These +functions are "error handling middleware", and can be used for handling +errors that occurred in previous handlers (E.g. from calling `next(err)`). +This is most used when you want to define arbitrary rendering of errors. + + + +```js +router.get('/error_route', function (req, res, next) { + return next(new Error('Bad Request')) +}) + +router.use(function (err, req, res, next) { + res.end(err.message) //= > "Bad Request" +}) +``` + +Error handling middleware will **only** be invoked when an error was given. As +long as the error is in the pipeline, normal middleware and handlers will be +bypassed - only error handling middleware will be invoked with an error. + +## Examples + +```js +// import our modules +var http = require('http') +var Router = require('router') +var finalhandler = require('finalhandler') +var compression = require('compression') +var bodyParser = require('body-parser') + +// store our message to display +var message = 'Hello World!' + +// initialize the router & server and add a final callback. +var router = Router() +var server = http.createServer(function onRequest (req, res) { + router(req, res, finalhandler(req, res)) +}) + +// use some middleware and compress all outgoing responses +router.use(compression()) + +// handle `GET` requests to `/message` +router.get('/message', function (req, res) { + res.statusCode = 200 + res.setHeader('Content-Type', 'text/plain;

This means that these versions of Node.js will *not* receive any updates, even in case of security issues, so using these release lines should be avoided, if at all possible. + +What you would do in this case is to convert all `new Buffer()` or `Buffer()` calls to use `Buffer.alloc()` or `Buffer.from()`, in the following way: + +- For `new Buffer(number)`, replace it with `Buffer.alloc(number)`. +- For `new Buffer(string)` (or `new Buffer(string, encoding)`), replace it with `Buffer.from(string)` (or `Buffer.from(string, encoding)`). +- For all other combinations of arguments (these are much rarer), also replace `new Buffer(...arguments)` with `Buffer.from(...arguments)`. + +Note that `Buffer.alloc()` is also _faster_ on the current Node.js versions than +`new Buffer(size).fill(0)`, which is what you would otherwise need to ensure zero-filling. + +Enabling eslint rule [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor) +or +[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md) +is recommended to avoid accidential unsafe Buffer API usage. + +There is also a [JSCodeshift codemod](https://github.com/joyeecheung/node-dep-codemod#dep005) +for automatically migrating Buffer constructors to `Buffer.alloc()` or `Buffer.from()`. +Note that it currently only works with cases where the arguments are literals or where the +constructor is invoked with two arguments. + +_If you currently support those older Node.js versions and dropping them would be a semver-major change +for you, or if you support older branches of your packages, consider using [Variant 2](#variant-2) +or [Variant 3](#variant-3) on older branches, so people using those older branches will also receive +the fix. That way, you will eradicate potential issues caused by unguarded Buffer API usage and +your users will not observe a runtime deprecation warning when running your code on Node.js 10._ + + +## Variant 2: Use a polyfill + +Utilize [safer-buffer](https://www.npmjs.com/package/safer-buffer) as a polyfill to support older +Node.js versions. + +You would take exacly the same steps as in [Variant 1](#variant-1), but with a polyfill +`const Buffer = require('safer-buffer').Buffer` in all files where you use the new `Buffer` api. + +Make sure that you do not use old `new Buffer` API — in any files where the line above is added, +using old `new Buffer()` API will _throw_. It will be easy to notice that in CI, though. + +Alternatively, you could use [buffer-from](https://www.npmjs.com/package/buffer-from) and/or +[buffer-alloc](https://www.npmjs.com/package/buffer-alloc) [ponyfills](https://ponyfill.com/) — +those are great, the only downsides being 4 deps in the tree and slightly more code changes to +migrate off them (as you would be using e.g. `Buffer.from` under a different name). If you need only +`Buffer.from` polyfilled — `buffer-from` alone which comes with no extra dependencies. + +_Alternatively, you could use [safe-buffer](https://www.npmjs.com/package/safe-buffer) — it also +provides a polyfill, but takes a different approach which has +[it's drawbacks](https://github.com/chalker/safer-buffer#why-not-safe-buffer). It will allow you +to also use the older `new Buffer()` API in your code, though — but that's arguably a benefit, as +it is problematic, can cause issues in your code, and will start emitting runtime deprecation +warnings starting with Node.js 10._ + +Note that in either case, it is important that you also remove all calls to the old Buffer +API manually — just throwing in `safe-buffer` doesn't fix the problem by itself, it just provides +a polyfill for the new API. I have seen people doing that mistake. + +Enabling eslint rule [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor) +or +[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md) +is recommended. + +_Don't forget to drop the polyfill usage once you drop support for Node.js < 4.5.0._ + + +## Variant 3 — manual detection, with safeguards + +This is useful if you create Buffer instances in only a few places (e.g. one), or you have your own +wrapper around them. + +### Buffer(0) + +This special case for creating empty buffers can be safely replaced with `Buffer.concat([])`, which +returns the same result all the way down to Node.js 0.8.x. + +### Buffer(notNumber) + +Before: + +```js +var buf = new Buffer(notNumber, encoding); +``` + +After: + +```js +var buf; +if (Buffer.from && Buffer.from !== Uint8Array.from) { + buf = Buffer.from(notNumber, encoding); +} else { + if (typeof notNumber === 'number') + throw new Error('The "size" argument must be of type number.'); + buf = new Buffer(notNumber, encoding); +} +``` + +`encoding` is optional. + +Note that the `typeof notNumber` before `new Buffer` is required (for cases when `notNumber` argument is not +hard-coded) and _is not caused by the deprecation of Buffer constructor_ — it's exactly _why_ the +Buffer constructor is deprecated. Ecosystem packages lacking this type-check caused numereous +security issues — situations when unsanitized user input could end up in the `Buffer(arg)` create +problems ranging from DoS to leaking sensitive information to the attacker from the process memory. + +When `notNumber` argument is hardcoded (e.g. literal `"abc"` or `[0,1,2]`), the `typeof` check can +be omitted. + +Also note that using TypeScript does not fix this problem for you — when libs written in +`TypeScript` are used from JS, or when user input ends up there — it behaves exactly as pure JS, as +all type checks are translation-time only and are not present in the actual JS code which TS +compiles to. + +### Buffer(number) + +For Node.js 0.10.x (and below) support: + +```js +var buf; +if (Buffer.alloc) { + buf = Buffer.alloc(number); +} else { + buf = new Buffer(number); + buf.fill(0); +} +``` + +Otherwise (Node.js ≥ 0.12.x): + +```js +const buf = Buffer.alloc ?

Before Node.js 8, this buffer contained + *arbitrary memory* for performance reasons, which could include anything ranging from + program source code to passwords and encryption keys. +- `new Buffer('abc')` creates a `Buffer` that contains the UTF-8-encoded version of + the string `'abc'`. A second argument could specify another encoding: For example, + `new Buffer(string, 'base64')` could be used to convert a Base64 string into the original + sequence of bytes that it represents. +- There are several other combinations of arguments. + +This meant that, in code like `var buffer = new Buffer(foo);`, *it is not possible to tell +what exactly the contents of the generated buffer are* without knowing the type of `foo`. + +Sometimes, the value of `foo` comes from an external source. For example, this function +could be exposed as a service on a web server, converting a UTF-8 string into its Base64 form: + +``` +function stringToBase64(req, res) { + // The request body should have the format of `{ string: 'foobar' }` + const rawBytes = new Buffer(req.body.string) + const encoded = rawBytes.toString('base64') + res.end({ encoded: encoded }) +} +``` + +Note that this code does *not* validate the type of `req.body.string`: + +- `req.body.string` is expected to be a string. If this is the case, all goes well. +- `req.body.string` is controlled by the client that sends the request. +- If `req.body.string` is the *number* `50`, the `rawBytes` would be 50 bytes: + - Before Node.js 8, the content would be uninitialized + - After Node.js 8, the content would be `50` bytes with the value `0` + +Because of the missing type check, an attacker could intentionally send a number +as part of the request. Using this, they can either: + +- Read uninitialized memory. This **will** leak passwords, encryption keys and other + kinds of sensitive information. (Information leak) +- Force the program to allocate a large amount of memory. For example, when specifying + `500000000` as the input value, each request will allocate 500MB of memory. + This can be used to either exhaust the memory available of a program completely + and make it crash, or slow it down significantly. (Denial of Service) + +Both of these scenarios are considered serious security issues in a real-world +web server context. + +when using `Buffer.from(req.body.string)` instead, passing a number will always +throw an exception instead, giving a controlled behaviour that can always be +handled by the program. + + +### The `Buffer()` constructor has been deprecated for a while.

Adding in `safe-buffer` _magically removes the lint warning_, but the behavior +remains identiсal to what we had before, and when launched on Node.js 6.x LTS — this dumps out +chunks of uninitialized memory. +_And this code will still emit runtime warnings on Node.js 10.x and above._ + +That was done by design. I first considered changing `safe-buffer`, prohibiting old API usage or +emitting warnings on it, but that significantly diverges from `safe-buffer` design. After some +discussion, it was decided to move my approach into a separate package, and _this is that separate +package_. + +This footgun is not imaginary — I observed top-downloaded packages doing that kind of thing, +«fixing» the lint warning by blindly including `safe-buffer` without any actual changes. + +Also in some cases, even if the API _was_ migrated to use of safe Buffer API — a random pull request +can bring unsafe Buffer API usage back to the codebase by adding new calls — and that could go +unnoticed even if you have a linter prohibiting that (becase of the reason stated above), and even +pass CI. _I also observed that being done in popular packages._ + +Some examples: + * [webdriverio](https://github.com/webdriverio/webdriverio/commit/05cbd3167c12e4930f09ef7cf93b127ba4effae4#diff-124380949022817b90b622871837d56cR31) + (a module with 548 759 downloads/month), + * [websocket-stream](https://github.com/maxogden/websocket-stream/commit/c9312bd24d08271687d76da0fe3c83493871cf61) + (218 288 d/m, fix in [maxogden/websocket-stream#142](https://github.com/maxogden/websocket-stream/pull/142)), + * [node-serialport](https://github.com/node-serialport/node-serialport/commit/e8d9d2b16c664224920ce1c895199b1ce2def48c) + (113 138 d/m, fix in [node-serialport/node-serialport#1510](https://github.com/node-serialport/node-serialport/pull/1510)), + * [karma](https://github.com/karma-runner/karma/commit/3d94b8cf18c695104ca195334dc75ff054c74eec) + (3 973 193 d/m, fix in [karma-runner/karma#2947](https://github.com/karma-runner/karma/pull/2947)), + * [spdy-transport](https://github.com/spdy-http2/spdy-transport/commit/5375ac33f4a62a4f65bcfc2827447d42a5dbe8b1) + (5 970 727 d/m, fix in [spdy-http2/spdy-transport#53](https://github.com/spdy-http2/spdy-transport/pull/53)). + * And there are a lot more over the ecosystem. + +I filed a PR at +[mysticatea/eslint-plugin-node#110](https://github.com/mysticatea/eslint-plugin-node/pull/110) to +partially fix that (for cases when that lint rule is used), but it is a semver-major change for +linter rules and presets, so it would take significant time for that to reach actual setups. +_It also hasn't been released yet (2018-03-20)._ + +Also, `safer-buffer` discourages the usage of `.allocUnsafe()`, which is often done by a mistake. +It still supports it with an explicit concern barier, by placing it under +`require('safer-buffer/dangereous')`. + +## But isn't throwing bad? + +Not really.

The `req` is +the Node.js HTTP request and the `path` is a urlencoded path to send (urlencoded, +not the actual file-system path). + +#### Options + +##### acceptRanges + +Enable or disable accepting ranged requests, defaults to true. +Disabling this will not send `Accept-Ranges` and ignore the contents +of the `Range` request header. + +##### cacheControl + +Enable or disable setting `Cache-Control` response header, defaults to +true. Disabling this will ignore the `immutable` and `maxAge` options. + +##### dotfiles + +Set how "dotfiles" are treated when encountered. A dotfile is a file +or directory that begins with a dot ("."). Note this check is done on +the path itself without checking if the path actually exists on the +disk. If `root` is specified, only the dotfiles above the root are +checked (i.e. the root itself can be within a dotfile when set +to "deny"). + + - `'allow'` No special treatment for dotfiles. + - `'deny'` Send a 403 for any request for a dotfile. + - `'ignore'` Pretend like the dotfile does not exist and 404. + +The default value is _similar_ to `'ignore'`, with the exception that +this default will not ignore the files within a directory that begins +with a dot, for backward-compatibility. + +##### end + +Byte offset at which the stream ends, defaults to the length of the file +minus 1. The end is inclusive in the stream, meaning `end: 3` will include +the 4th byte in the stream. + +##### etag + +Enable or disable etag generation, defaults to true. + +##### extensions + +If a given file doesn't exist, try appending one of the given extensions, +in the given order. By default, this is disabled (set to `false`). An +example value that will serve extension-less HTML files: `['html', 'htm']`. +This is skipped if the requested file already has an extension. + +##### immutable + +Enable or disable the `immutable` directive in the `Cache-Control` response +header, defaults to `false`. If set to `true`, the `maxAge` option should +also be specified to enable caching. The `immutable` directive will prevent +supported clients from making conditional requests during the life of the +`maxAge` option to check if the file has changed. + +##### index + +By default send supports "index.html" files, to disable this +set `false` or to supply a new index pass a string or an array +in preferred order. + +##### lastModified + +Enable or disable `Last-Modified` header, defaults to true. Uses the file +system's last modified value. + +##### maxAge + +Provide a max-age in milliseconds for http caching, defaults to 0. +This can also be a string accepted by the +[ms](https://www.npmjs.org/package/ms#readme) module. + +##### root + +Serve files relative to `path`. + +##### start + +Byte offset at which the stream starts, defaults to 0. The start is inclusive, +meaning `start: 2` will include the 3rd byte in the stream. + +#### Events + +The `SendStream` is an event emitter and will emit the following events: + + - `error` an error occurred `(err)` + - `directory` a directory was requested `(res, path)` + - `file` a file was requested `(path, stat)` + - `headers` the headers are about to be set on a file `(res, path, stat)` + - `stream` file streaming has started `(stream)` + - `end` streaming has completed + +#### .pipe + +The `pipe` method is used to pipe the response into the Node.js HTTP response +object, typically `send(req, path, options).pipe(res)`. + +## Error-handling + +By default when no `error` listeners are present an automatic response will be +made, otherwise you have full control over the response, aka you may show a 5xx +page etc. + +## Caching + +It does _not_ perform internal caching, you should use a reverse proxy cache +such as Varnish for this, or those fancy things called CDNs. If your +application is small enough that it would benefit from single-node memory +caching, it's small enough that it does not need caching at all ;). + +## Debugging + +To enable `debug()` instrumentation output export __DEBUG__: + +``` +$ DEBUG=send node app +``` + +## Running tests + +``` +$ npm install +$ npm test +``` + +## Examples + +### Serve a specific file + +This simple example will send a specific file to all requests. + +```js +var http = require('http') +var send = require('send') + +var server = http.createServer(function onRequest (req, res) { + send(req, '/path/to/index.html') + .pipe(res) +}) + +server.listen(3000) +``` + +### Serve all files from a directory + +This simple example will just serve up all the files in a +given directory as the top-level.

The file to serve will be determined by combining `req.url` +with the provided root directory. When a file is not found, instead of +sending a 404 response, this module will instead call `next()` to move on +to the next middleware, allowing for stacking and fall-backs. + +#### Options + +##### acceptRanges + +Enable or disable accepting ranged requests, defaults to true. +Disabling this will not send `Accept-Ranges` and ignore the contents +of the `Range` request header. + +##### cacheControl + +Enable or disable setting `Cache-Control` response header, defaults to +true. Disabling this will ignore the `immutable` and `maxAge` options. + +##### dotfiles + +Set how "dotfiles" are treated when encountered. A dotfile is a file +or directory that begins with a dot ("."). Note this check is done on +the path itself without checking if the path actually exists on the +disk. If `root` is specified, only the dotfiles above the root are +checked (i.e. the root itself can be within a dotfile when set +to "deny"). + + - `'allow'` No special treatment for dotfiles. + - `'deny'` Deny a request for a dotfile and 403/`next()`. + - `'ignore'` Pretend like the dotfile does not exist and 404/`next()`. + +The default value is `'ignore'`. + +##### etag + +Enable or disable etag generation, defaults to true. + +##### extensions + +Set file extension fallbacks. When set, if a file is not found, the given +extensions will be added to the file name and search for. The first that +exists will be served. Example: `['html', 'htm']`. + +The default value is `false`. + +##### fallthrough + +Set the middleware to have client errors fall-through as just unhandled +requests, otherwise forward a client error. The difference is that client +errors like a bad request or a request to a non-existent file will cause +this middleware to simply `next()` to your next middleware when this value +is `true`. When this value is `false`, these errors (even 404s), will invoke +`next(err)`. + +Typically `true` is desired such that multiple physical directories can be +mapped to the same web address or for routes to fill in non-existent files. + +The value `false` can be used if this middleware is mounted at a path that +is designed to be strictly a single file system directory, which allows for +short-circuiting 404s for less overhead. This middleware will also reply to +all methods. + +The default value is `true`. + +##### immutable + +Enable or disable the `immutable` directive in the `Cache-Control` response +header, defaults to `false`. If set to `true`, the `maxAge` option should +also be specified to enable caching. The `immutable` directive will prevent +supported clients from making conditional requests during the life of the +`maxAge` option to check if the file has changed. + +##### index + +By default this module will send "index.html" files in response to a request +on a directory. To disable this set `false` or to supply a new index pass a +string or an array in preferred order. + +##### lastModified + +Enable or disable `Last-Modified` header, defaults to true. Uses the file +system's last modified value. + +##### maxAge + +Provide a max-age in milliseconds for http caching, defaults to 0. This +can also be a string accepted by the [ms](https://www.npmjs.org/package/ms#readme) +module. + +##### redirect + +Redirect to trailing "/" when the pathname is a dir. Defaults to `true`. + +##### setHeaders + +Function to set custom headers on response. Alterations to the headers need to +occur synchronously. The function is called as `fn(res, path, stat)`, where +the arguments are: + + - `res` the response object + - `path` the file path that is being sent + - `stat` the stat object of the file that is being sent + +## Examples + +### Serve files with vanilla node.js http server + +```js +const finalhandler = require('finalhandler') +const http = require('http') +const serveStatic = require('serve-static') + +// Serve up public/ftp folder +const serve = serveStatic('public/ftp', { index: ['index.html', 'index.htm'] }) + +// Create server +const server = http.createServer((req, res) => { + serve(req, res, finalhandler(req, res)) +}) + +// Listen +server.listen(3000) +``` + +### Serve all files as downloads + +```js +const contentDisposition = require('content-disposition') +const finalhandler = require('finalhandler') +const http = require('http') +const serveStatic = require('serve-static') + +// Serve up public/ftp folder +const serve = serveStatic('public/ftp', { + index: false, + setHeaders: setHeaders +}) + +// Set header to force download +function setHeaders (res, path) { + res.setHeader('Content-Disposition', contentDisposition(path)) +} + +// Create server +const server = http.createServer((req, res) => { + serve(req, res, finalhandler(req, res)) +}) + +// Listen +server.listen(3000) +``` + +### Serving using express + +#### Simple + +This is a simple example of using Express. + +```js +const express = require('express') +const serveStatic = require('serve-static') + +const app = express() + +app.use(serveStatic('public/ftp', { index: ['default.html', 'default.htm'] })) +app.listen(3000) +``` + +#### Multiple roots + +This example shows a simple way to search through multiple directories. +Files are searched for in `public-optimized/` first, then `public/` second +as a fallback. + +```js +const express = require('express') +const path = require('path') +const serveStatic = require('serve-static') + +const app = express() + +app.use(serveStatic(path.join(__dirname, 'public-optimized'))) +app.use(serveStatic(path.join(__dirname, 'public'))) +app.listen(3000) +``` + +#### Different settings for paths + +This example shows how to set a different max age depending on the served +file.

Please see the [Goals](https://github.com/socketio/engine.io#goals) section for more information. + +#### Auto-reconnection support + +Unless instructed otherwise a disconnected client will try to reconnect forever, until the server is available again. Please see the available reconnection options [here](https://socket.io/docs/v3/client-api/#new-Manager-url-options). + +#### Disconnection detection + +A heartbeat mechanism is implemented at the Engine.IO level, allowing both the server and the client to know when the other one is not responding anymore. + +That functionality is achieved with timers set on both the server and the client, with timeout values (the `pingInterval` and `pingTimeout` parameters) shared during the connection handshake. Those timers require any subsequent client calls to be directed to the same server, hence the `sticky-session` requirement when using multiples nodes. + +#### Binary support + +Any serializable data structures can be emitted, including: + +- [ArrayBuffer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer) and [Blob](https://developer.mozilla.org/en-US/docs/Web/API/Blob) in the browser +- [ArrayBuffer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer) and [Buffer](https://nodejs.org/api/buffer.html) in Node.js + +#### Simple and convenient API + +Sample code: + +```js +io.on('connection', socket => { + socket.emit('request', /* … */); // emit an event to the socket + io.emit('broadcast', /* … */); // emit an event to all connected sockets + socket.on('reply', () => { /* … */ }); // listen to the event +}); +``` + +#### Cross-browser + +Browser support is tested in Sauce Labs: + +[![Sauce Test Status](https://saucelabs.com/browser-matrix/socket.svg)](https://saucelabs.com/u/socket) + +#### Multiplexing support + +In order to create separation of concerns within your application (for example per module, or based on permissions), Socket.IO allows you to create several `Namespaces`, which will act as separate communication channels but will share the same underlying connection. + +#### Room support + +Within each `Namespace`, you can define arbitrary channels, called `Rooms`, that sockets can join and leave. You can then broadcast to any given room, reaching every socket that has joined it. + +This is a useful feature to send notifications to a group of users, or to a given user connected on several devices for example. + + +**Note:** Socket.IO is not a WebSocket implementation. Although Socket.IO indeed uses WebSocket as a transport when possible, it adds some metadata to each packet: the packet type, the namespace and the ack id when a message acknowledgement is needed. That is why a WebSocket client will not be able to successfully connect to a Socket.IO server, and a Socket.IO client will not be able to connect to a WebSocket server (like `ws://echo.websocket.org`) either. Please see the protocol specification [here](https://github.com/socketio/socket.io-protocol). + +## Installation + +```bash +// with npm +npm install socket.io + +// with yarn +yarn add socket.io +``` + +## How to use + +The following example attaches socket.io to a plain Node.JS +HTTP server listening on port `3000`. + +```js +const server = require('http').createServer(); +const io = require('socket.io')(server); +io.on('connection', client => { + client.on('event', data => { /* … */ }); + client.on('disconnect', () => { /* … */ }); +}); +server.listen(3000); +``` + +### Standalone + +```js +const io = require('socket.io')(); +io.on('connection', client => { ... }); +io.listen(3000); +``` + +### Module syntax + +```js +import { Server } from "socket.io"; +const io = new Server(server); +io.listen(3000); +``` + +### In conjunction with Express + +Starting with **3.0**, express applications have become request handler +functions that you pass to `http` or `http` `Server` instances. You need +to pass the `Server` to `socket.io`, not the express application +function. Also make sure to call `.listen` on the `server`, not the `app`. + +```js +const app = require('express')(); +const server = require('http').createServer(app); +const io = require('socket.io')(server); +io.on('connection', () => { /* … */ }); +server.listen(3000); +``` + +### In conjunction with Koa + +Like Express.JS, Koa works by exposing an application as a request +handler function, but only by calling the `callback` method. + +```js +const app = require('koa')(); +const server = require('http').createServer(app.callback()); +const io = require('socket.io')(server); +io.on('connection', () => { /* … */ }); +server.listen(3000); +``` + +### In conjunction with Fastify + +To integrate Socket.io in your Fastify application you just need to +register `fastify-socket.io` plugin. It will create a `decorator` +called `io`. + +```js +const app = require('fastify')(); +app.register(require('fastify-socket.io')); +app.ready().then(() => { + app.io.on('connection', () => { /* … */ }); +}) +app.listen(3000); +``` + +## Documentation + +Please see the documentation [here](https://socket.io/docs/). + +The source code of the website can be found [here](https://github.com/socketio/socket.io-website). Contributions are welcome! + +## Debug / logging + +Socket.IO is powered by [debug](https://github.com/visionmedia/debug). +In order to see all the debug output, run your app with the environment variable +`DEBUG` including the desired scope. + +To see the output from all of Socket.IO's debugging scopes you can use: + +``` +DEBUG=socket.io* node myapp +``` + +## Testing + +``` +npm test +``` +This runs the `gulp` task `test`. By default the test will be run with the source code in `lib` directory. + +Set the environmental variable `TEST_VERSION` to `compat` to test the transpiled es5-compat version of the code. + +The `gulp` task `test` will always transpile the source code into es5 and export to `dist` first before running the test. + + +## Backers + +Support us with a monthly donation and help us continue our activities.

Status][coveralls-image]][coveralls-url] + +This is a large database of mime types and information about them. +It consists of a single, public JSON file and does not include any logic, +allowing it to remain as un-opinionated as possible with an API. +It aggregates data from the following sources: + +- http://www.iana.org/assignments/media-types/media-types.xhtml +- http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types +- http://hg.nginx.org/nginx/raw-file/default/conf/mime.types + +## Installation + +```bash +npm install mime-db +``` + +### Database Download + +If you're crazy enough to use this in the browser, you can just grab the +JSON file using [jsDelivr](https://www.jsdelivr.com/).

This needs to be a [primary source](https://en.wikipedia.org/wiki/Primary_source); + links to type aggregating sites and Wikipedia are _not acceptable_. + +To update the build, run `npm run build`. + +### Adding Custom Media Types + +The best way to get new media types included in this library is to register +them with the IANA. The community registration procedure is outlined in +[RFC 6838 section 5](http://tools.ietf.org/html/rfc6838#section-5). Types +registered with the IANA are automatically pulled into this library. + +If that is not possible / feasible, they can be added directly here as a +"custom" type. To do this, it is required to have a primary source that +definitively lists the media type. If an extension is going to be listed as +associateed with this media type, the source must definitively link the +media type and extension as well. + +[ci-image]:

If the request has no body, +even if there is a `Content-Type` header, then `null` is returned. If the +`Content-Type` header is invalid or does not matches any of the `types`, then +`false` is returned. Otherwise, a string of the type that matched is returned. + +The `request` argument is expected to be a Node.js HTTP request. The `types` +argument is an array of type strings. + +Each type in the `types` array can be one of the following: + +- A file extension name such as `json`. This name will be returned if matched. +- A mime type such as `application/json`. +- A mime type with a wildcard such as `*/*` or `*/json` or `application/*`. + The full mime type will be returned if matched. +- A suffix such as `+json`. This can be combined with a wildcard such as + `*/vnd+json` or `application/*+json`. The full mime type will be returned + if matched. + +Some examples to illustrate the inputs and returned value: + +```js +// req.headers.content-type = 'application/json' + +typeis(req, ['json']) // => 'json' +typeis(req, ['html', 'json']) // => 'json' +typeis(req, ['application/*']) // => 'application/json' +typeis(req, ['application/json']) // => 'application/json' + +typeis(req, ['html']) // => false +``` + +### typeis.hasBody(request) + +Returns a Boolean if the given `request` has a body, regardless of the +`Content-Type` header. + +Having a body has no relation to how large the body is (it may be 0 bytes). +This is similar to how file existence works. If a body does exist, then this +indicates that there is data to read from the Node.js request stream. + +```js +if (typeis.hasBody(req)) { + // read the body, since there is one + + req.on('data', function (chunk) { + // ... + }) +} +``` + +### typeis.is(mediaType, types) + +Checks if the `mediaType` is one of the `types`. If the `mediaType` is invalid +or does not matches any of the `types`, then `false` is returned. Otherwise, a +string of the type that matched is returned. + +The `mediaType` argument is expected to be a +[media type](https://tools.ietf.org/html/rfc6838) string. The `types` argument +is an array of type strings. + +Each type in the `types` array can be one of the following: + +- A file extension name such as `json`. This name will be returned if matched. +- A mime type such as `application/json`. +- A mime type with a wildcard such as `*/*` or `*/json` or `application/*`. + The full mime type will be returned if matched. +- A suffix such as `+json`. This can be combined with a wildcard such as + `*/vnd+json` or `application/*+json`. The full mime type will be returned + if matched. + +Some examples to illustrate the inputs and returned value: + +```js +var mediaType = 'application/json' + +typeis.is(mediaType, ['json']) // => 'json' +typeis.is(mediaType, ['html', 'json']) // => 'json' +typeis.is(mediaType, ['application/*']) // => 'application/json' +typeis.is(mediaType, ['application/json']) // => 'application/json' + +typeis.is(mediaType, ['html']) // => false +``` + +### typeis.match(expected, actual) + +Match the type string `expected` with `actual`, taking in to account wildcards. +A wildcard can only be in the type of the subtype part of a media type and only +in the `expected` value (as `actual` should be the real media type to match). A +suffix can still be included even with a wildcard subtype. If an input is +malformed, `false` will be returned. + +```js +typeis.match('text/html', 'text/html') // => true +typeis.match('*/html', 'text/html') // => true +typeis.match('text/*', 'text/html') // => true +typeis.match('*/*', 'text/html') // => true +typeis.match('*/*+json', 'application/x-custom+json') // => true +``` + +### typeis.normalize(type) + +Normalize a `type` string. This works by performing the following: + +- If the `type` is not a string, `false` is returned. +- If the string starts with `+` (so it is a `+suffix` shorthand like `+json`), + then it is expanded to contain the complete wildcard notation of `*/*+suffix`. +- If the string contains a `/`, then it is returned as the type. +- Else the string is assumed to be a file extension and the mapped media type is + returned, or `false` is there is no mapping. + +This includes two special mappings: + +- `'multipart'` -> `'multipart/*'` +- `'urlencoded'` -> `'application/x-www-form-urlencoded'` + +## Examples + +### Example body parser + +```js +var express = require('express') +var typeis = require('type-is') + +var app = express() + +app.use(function bodyParser (req, res, next) { + if (!typeis.hasBody(req)) { + return next() + } + + switch (typeis(req, ['urlencoded', 'json', 'multipart'])) { + case 'urlencoded': + // parse urlencoded body + throw new Error('implement urlencoded body parsing') + case 'json': + // parse json body + throw new Error('implement json body parsing') + case 'multipart': + // parse multipart body + throw new Error('implement multipart body parsing') + default: + // 415 error code + res.statusCode = 415 + res.end() + break + } +}) +``` + +## License + +[MIT](LICENSE) + +[ci-image]: https://badgen.net/github/checks/jshttp/type-is/master?label=ci +[ci-url]: https://github.com/jshttp/type-is/actions/workflows/ci.yml +[coveralls-image]: https://badgen.net/coveralls/c/github/jshttp/type-is/master +[coveralls-url]: https://coveralls.io/r/jshttp/type-is?branch=master +[node-version-image]: https://badgen.net/npm/node/type-is +[node-version-url]: https://nodejs.org/en/download +[npm-downloads-image]: https://badgen.net/npm/dm/type-is +[npm-url]: https://npmjs.org/package/type-is +[npm-version-image]: https://badgen.net/npm/v/type-is +[travis-image]: https://badgen.net/travis/jshttp/type-is/master +[travis-url]: https://travis-ci.org/jshttp/type-is diff --git a/node_modules/type-is/index.js b/node_modules/type-is/index.js new file mode 100644 index 0000000..37d6da3 --- /dev/null +++ b/node_modules/type-is/index.js @@ -0,0 +1,240 @@ +/*! + * type-is + * Copyright(c) 2014 Jonathan Ong + * Copyright(c) 2014-2015 Douglas Christopher Wilson + * MIT Licensed + */ + +'use strict' + +/** + * Module dependencies. + * @private + */ + +var contentType = require('content-type') +var mime = require('mime-types') +var typer = require('media-typer') + +/** + * Module exports. + * @public + */ + +module.exports = typeofrequest +module.exports.is = typeis +module.exports.hasBody = hasbody +module.exports.normalize = normalize +module.exports.match = mimeMatch + +/** + * Compare a `value` content-type with `types`. + * Each `type` can be an extension like `html`, + * a special shortcut like `multipart` or `urlencoded`, + * or a mime type. + * + * If no types match, `false` is returned. + * Otherwise, the first `type` that matches is returned. + * + * @param {String} value + * @param {Array} types + * @public + */ + +function typeis (value, types_) { + // Backward compatibility.

This +can be useful to enhance security in systems where a user can put a package in +the package search path of an application of another user, due to how the +Node.js resolver algorithm works. + +#### Legacy opt-in for performance + +If you are running on an old version of Node.js (prior to v18.14.0), ws also +supports the [utf-8-validate][] module: + +``` +npm install --save-optional utf-8-validate +``` + +This contains a binary polyfill for [`buffer.isUtf8()`][]. + +To force ws not to use utf-8-validate, use the +[`WS_NO_UTF_8_VALIDATE`](./doc/ws.md#ws_no_utf_8_validate) environment variable. + +## API docs + +See [`/doc/ws.md`](./doc/ws.md) for Node.js-like documentation of ws classes and +utility functions. + +## WebSocket compression + +ws supports the [permessage-deflate extension][permessage-deflate] which enables +the client and server to negotiate a compression algorithm and its parameters, +and then selectively apply it to the data payloads of each WebSocket message. + +The extension is disabled by default on the server and enabled by default on the +client. It adds a significant overhead in terms of performance and memory +consumption so we suggest to enable it only if it is really needed. + +Note that Node.js has a variety of issues with high-performance compression, +where increased concurrency, especially on Linux, can lead to [catastrophic +memory fragmentation][node-zlib-bug] and slow performance. If you intend to use +permessage-deflate in production, it is worthwhile to set up a test +representative of your workload and ensure Node.js/zlib will handle it with +acceptable performance and memory usage. + +Tuning of permessage-deflate can be done via the options defined below. You can +also use `zlibDeflateOptions` and `zlibInflateOptions`, which is passed directly +into the creation of [raw deflate/inflate streams][node-zlib-deflaterawdocs]. + +See [the docs][ws-server-options] for more options. + +```js +import WebSocket, { WebSocketServer } from 'ws'; + +const wss = new WebSocketServer({ + port: 8080, + perMessageDeflate: { + zlibDeflateOptions: { + // See zlib defaults. + chunkSize: 1024, + memLevel: 7, + level: 3 + }, + zlibInflateOptions: { + chunkSize: 10 * 1024 + }, + // Other options settable: + clientNoContextTakeover: true, // Defaults to negotiated value. + serverNoContextTakeover: true, // Defaults to negotiated value. + serverMaxWindowBits: 10, // Defaults to negotiated value. + // Below options specified as default values. + concurrencyLimit: 10, // Limits zlib concurrency for perf. + threshold: 1024 // Size (in bytes) below which messages + // should not be compressed if context takeover is disabled. + } +}); +``` + +The client will only use the extension if it is supported and enabled on the +server. To always disable the extension on the client, set the +`perMessageDeflate` option to `false`. + +```js +import WebSocket from 'ws'; + +const ws = new WebSocket('ws://www.host.com/path', { + perMessageDeflate: false +}); +``` + +## Usage examples + +### Sending and receiving text data + +```js +import WebSocket from 'ws'; + +const ws = new WebSocket('ws://www.host.com/path'); + +ws.on('error', console.error); + +ws.on('open', function open() { + ws.send('something'); +}); + +ws.on('message', function message(data) { + console.log('received: %s', data); +}); +``` + +### Sending binary data + +```js +import WebSocket from 'ws'; + +const ws = new WebSocket('ws://www.host.com/path'); + +ws.on('error', console.error); + +ws.on('open', function open() { + const array = new Float32Array(5); + + for (var i = 0; i < array.length; ++i) { + array[i] = i / 2; + } + + ws.send(array); +}); +``` + +### Simple server + +```js +import { WebSocketServer } from 'ws'; + +const wss = new WebSocketServer({ port: 8080 }); + +wss.on('connection', function connection(ws) { + ws.on('error', console.error); + + ws.on('message', function message(data) { + console.log('received: %s', data); + }); + + ws.send('something'); +}); +``` + +### External HTTP/S server + +```js +import { createServer } from 'https'; +import { readFileSync } from 'fs'; +import { WebSocketServer } from 'ws'; + +const server = createServer({ + cert: readFileSync('/path/to/cert.pem'), + key: readFileSync('/path/to/key.pem') +}); +const wss = new WebSocketServer({ server }); + +wss.on('connection', function connection(ws) { + ws.on('error', console.error); + + ws.on('message', function message(data) { + console.log('received: %s', data); + }); + + ws.send('something'); +}); + +server.listen(8080); +``` + +### Multiple servers sharing a single HTTP/S server + +```js +import { createServer } from 'http'; +import { WebSocketServer } from 'ws'; + +const server = createServer(); +const wss1 = new WebSocketServer({ noServer: true }); +const wss2 = new WebSocketServer({ noServer: true }); + +wss1.on('connection', function connection(ws) { + ws.on('error', console.error); + + // ... +}); + +wss2.on('connection', function connection(ws) { + ws.on('error', console.error); + + // ... +}); + +server.on('upgrade', function upgrade(request, socket, head) { + const { pathname } = new URL(request.url, 'wss://base.url'); + + if (pathname === '/foo') { + wss1.handleUpgrade(request, socket, head, function done(ws) { + wss1.emit('connection', ws, request); + }); + } else if (pathname === '/bar') { + wss2.handleUpgrade(request, socket, head, function done(ws) { + wss2.emit('connection', ws, request); + }); + } else { + socket.destroy(); + } +}); + +server.listen(8080); +``` + +### Client authentication + +```js +import { createServer } from 'http'; +import { WebSocketServer } from 'ws'; + +function onSocketError(err) { + console.error(err); +} + +const server = createServer(); +const wss = new WebSocketServer({ noServer: true }); + +wss.on('connection', function connection(ws, request, client) { + ws.on('error', console.error); + + ws.on('message', function message(data) { + console.log(`Received message ${data} from user ${client}`); + }); +}); + +server.on('upgrade', function upgrade(request, socket, head) { + socket.on('error', onSocketError); + + // This function is not defined on purpose.

You might want to add a ping listener on your clients to +prevent that. A simple implementation would be: + +```js +import WebSocket from 'ws'; + +function heartbeat() { + clearTimeout(this.pingTimeout); + + // Use `WebSocket#terminate()`, which immediately destroys the connection, + // instead of `WebSocket#close()`, which waits for the close timer. + // Delay should be equal to the interval at which your server + // sends out pings plus a conservative assumption of the latency. + this.pingTimeout = setTimeout(() => { + this.terminate(); + }, 30000 + 1000); +} + +const client = new WebSocket('wss://websocket-echo.com/'); + +client.on('error', console.error); +client.on('open', heartbeat); +client.on('ping', heartbeat); +client.on('close', function clear() { + clearTimeout(this.pingTimeout); +}); +``` + +### How to connect via a proxy? + +Use a custom `http.Agent` implementation like [https-proxy-agent][] or +[socks-proxy-agent][]. + +## Changelog + +We're using the GitHub [releases][changelog] for changelog entries. + +## License + +[MIT](LICENSE) + +[`buffer.isutf8()`]: https://nodejs.org/api/buffer.html#bufferisutf8input +[bufferutil]: https://github.com/websockets/bufferutil +[changelog]: https://github.com/websockets/ws/releases +[client-report]: http://websockets.github.io/ws/autobahn/clients/ +[https-proxy-agent]: https://github.com/TooTallNate/node-https-proxy-agent +[node-zlib-bug]: https://github.com/nodejs/node/issues/8871 +[node-zlib-deflaterawdocs]: + https://nodejs.org/api/zlib.html#zlib_zlib_createdeflateraw_options +[permessage-deflate]: https://tools.ietf.org/html/rfc7692 +[server-report]: http://websockets.github.io/ws/autobahn/servers/ +[session-parse-example]: ./examples/express-session-parse +[socks-proxy-agent]: https://github.com/TooTallNate/node-socks-proxy-agent +[utf-8-validate]: https://github.com/websockets/utf-8-validate +[ws-server-options]: ./doc/ws.md#new-websocketserveroptions-callback diff --git a/node_modules/ws/browser.js b/node_modules/ws/browser.js new file mode 100644 index 0000000..ca4f628 --- /dev/null +++ b/node_modules/ws/browser.js @@ -0,0 +1,8 @@ +'use strict'; + +module.exports = function () { + throw new Error( + 'ws does not work in the browser.
