These might 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. + +## 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('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('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('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('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 { parse } from 'url'; +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) { + // ... +}); + +wss2.on('connection', function connection(ws) { + // ... +}); + +server.on('upgrade', function upgrade(request, socket, head) { + const { pathname } = parse(request.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'; + +const server = createServer(); +const wss = new WebSocketServer({ noServer: true }); + +wss.on('connection', function connection(ws, request, client) { + ws.on('message', function message(data) { + console.log(`Received message ${data} from user ${client}`); + }); +}); + +server.on('upgrade', function upgrade(request, socket, head) { + // 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('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) + +[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 +[ws-server-options]: ./doc/ws.md#new-websocketserveroptions-callback diff --git a/testing/xpcshell/node-ws/SECURITY.md b/testing/xpcshell/node-ws/SECURITY.md new file mode 100644 index 0000000000..0baf19a63b --- /dev/null +++ b/testing/xpcshell/node-ws/SECURITY.md @@ -0,0 +1,39 @@ +# Security Guidelines + +Please contact us directly at **security@3rd-Eden.com** for any bug that might +impact the security of this project.

It must + be extended from the original `WebSocket`. Defaults to `WebSocket`. +- `callback` {Function} + +Create a new server instance. One and only one of `port`, `server` or `noServer` +must be provided or an error is thrown. An HTTP server is automatically created, +started, and used if `port` is set. To use an external HTTP/S server instead, +specify only `server` or `noServer`. In this case the HTTP/S server must be +started manually. The "noServer" mode allows the WebSocket server to be +completely detached from the HTTP/S server. This makes it possible, for example, +to share a single HTTP/S server between multiple WebSocket servers. + +> **NOTE:** Use of `verifyClient` is discouraged. Rather handle client +> authentication in the `upgrade` event of the HTTP server. See examples for +> more details. + +If `verifyClient` is not set then the handshake is automatically accepted. If it +has a single parameter then `ws` will invoke it with the following argument: + +- `info` {Object} + - `origin` {String} The value in the Origin header indicated by the client. + - `req` {http.IncomingMessage} The client HTTP GET request. + - `secure` {Boolean} `true` if `req.socket.authorized` or + `req.socket.encrypted` is set. + +The return value (`Boolean`) of the function determines whether or not to accept +the handshake. + +If `verifyClient` has two parameters then `ws` will invoke it with the following +arguments: + +- `info` {Object} Same as above. +- `cb` {Function} A callback that must be called by the user upon inspection of + the `info` fields. Arguments in this callback are: + - `result` {Boolean} Whether or not to accept the handshake. + - `code` {Number} When `result` is `false` this field determines the HTTP + error status code to be sent to the client. + - `name` {String} When `result` is `false` this field determines the HTTP + reason phrase. + - `headers` {Object} When `result` is `false` this field determines additional + HTTP headers to be sent to the client. For example, + `{ 'Retry-After': 120 }`. + +`handleProtocols` takes two arguments: + +- `protocols` {Set} The list of WebSocket subprotocols indicated by the client + in the `Sec-WebSocket-Protocol` header. +- `request` {http.IncomingMessage} The client HTTP GET request. + +The returned value sets the value of the `Sec-WebSocket-Protocol` header in the +HTTP 101 response. If returned value is `false` the header is not added in the +response. + +If `handleProtocols` is not set then the first of the client's requested +subprotocols is used. + +`perMessageDeflate` can be used to control the behavior of [permessage-deflate +extension][permessage-deflate]. The extension is disabled when `false` (default +value). If an object is provided then that is extension parameters: + +- `serverNoContextTakeover` {Boolean} Whether to use context takeover or not. +- `clientNoContextTakeover` {Boolean} Acknowledge disabling of client context + takeover. +- `serverMaxWindowBits` {Number} The value of `windowBits`. +- `clientMaxWindowBits` {Number} Request a custom client window size. +- `zlibDeflateOptions` {Object} [Additional options][zlib-options] to pass to + zlib on deflate. +- `zlibInflateOptions` {Object} [Additional options][zlib-options] to pass to + zlib on inflate. +- `threshold` {Number} Payloads smaller than this will not be compressed if + context takeover is disabled. Defaults to 1024 bytes. +- `concurrencyLimit` {Number} The number of concurrent calls to zlib. Calls + above this limit will be queued. Default 10. You usually won't need to touch + this option. See [this issue][concurrency-limit] for more details. + +If a property is empty then either an offered configuration or a default value +is used. When sending a fragmented message the length of the first fragment is +compared to the threshold. This determines if compression is used for the entire +message. + +`callback` will be added as a listener for the `listening` event on the HTTP +server when not operating in "noServer" mode. + +### Event: 'close' + +Emitted when the server closes. This event depends on the `'close'` event of +HTTP server only when it is created internally. In all other cases, the event is +emitted independently. + +### Event: 'connection' + +- `websocket` {WebSocket} +- `request` {http.IncomingMessage} + +Emitted when the handshake is complete. `request` is the http GET request sent +by the client. Useful for parsing authority headers, cookie headers, and other +information. + +### Event: 'error' + +- `error` {Error} + +Emitted when an error occurs on the underlying server. + +### Event: 'headers' + +- `headers` {Array} +- `request` {http.IncomingMessage} + +Emitted before the response headers are written to the socket as part of the +handshake. This allows you to inspect/modify the headers before they are sent. + +### Event: 'listening' + +Emitted when the underlying server has been bound. + +### Event: 'wsClientError' + +- `error` {Error} +- `socket` {net.Socket|tls.Socket} +- `request` {http.IncomingMessage} + +Emitted when an error occurs before the WebSocket connection is established. +`socket` and `request` are respectively the socket and the HTTP request from +which the error originated. The listener of this event is responsible for +closing the socket. When the `'wsClientError'` event is emitted there is no +`http.ServerResponse` object, so any HTTP response, including the response +headers and body, must be written directly to the `socket`. If there is no +listener for this event, the socket is closed with a default 4xx response +containing a descriptive error message. + +### server.address() + +Returns an object with `port`, `family`, and `address` properties specifying the +bound address, the address family name, and port of the server as reported by +the operating system if listening on an IP socket. If the server is listening on +a pipe or UNIX domain socket, the name is returned as a string. + +### server.clients + +- {Set} + +A set that stores all connected clients. Please note that this property is only +added when the `clientTracking` is truthy. + +### server.close([callback]) + +Prevent the server from accepting new connections and close the HTTP server if +created internally. If an external HTTP server is used via the `server` or +`noServer` constructor options, it must be closed manually. Existing connections +are not closed automatically. The server emits a `'close'` event when all +connections are closed unless an external HTTP server is used and client +tracking is disabled. In this case the `'close'` event is emitted in the next +tick. The optional callback is called when the `'close'` event occurs and +receives an `Error` if the server is already closed. + +### server.handleUpgrade(request, socket, head, callback) + +- `request` {http.IncomingMessage} The client HTTP GET request. +- `socket` {net.Socket|tls.Socket} The network socket between the server and + client. +- `head` {Buffer} The first packet of the upgraded stream. +- `callback` {Function}. + +Handle a HTTP upgrade request. When the HTTP server is created internally or +when the HTTP server is passed via the `server` option, this method is called +automatically. When operating in "noServer" mode, this method must be called +manually. + +If the upgrade is successful, the `callback` is called with two arguments: + +- `websocket` {WebSocket} A `WebSocket` object. +- `request` {http.IncomingMessage} The client HTTP GET request. + +### server.shouldHandle(request) + +- `request` {http.IncomingMessage} The client HTTP GET request. + +See if a given request should be handled by this server. By default this method +validates the pathname of the request, matching it against the `path` option if +provided. The return value, `true` or `false`, determines whether or not to +accept the handshake. + +This method can be overridden when a custom handling logic is required. + +## Class: WebSocket + +This class represents a WebSocket. It extends the `EventEmitter`. + +### Ready state constants + +| Constant | Value | Description | +| ---------- | ----- | ------------------------------------------------ | +| CONNECTING | 0 | The connection is not yet open. | +| OPEN | 1 | The connection is open and ready to communicate. | +| CLOSING | 2 | The connection is in the process of closing. | +| CLOSED | 3 | The connection is closed. | + +### new WebSocket(address[, protocols][, options]) + +- `address` {String|url.URL} The URL to which to connect. +- `protocols` {String|Array} The list of subprotocols. +- `options` {Object} + - `followRedirects` {Boolean} Whether or not to follow redirects. Defaults to + `false`. + - `generateMask` {Function} The function used to generate the masking key. It + takes a `Buffer` that must be filled synchronously and is called before a + message is sent, for each message. By default the buffer is filled with + cryptographically strong random bytes. + - `handshakeTimeout` {Number} Timeout in milliseconds for the handshake + request. This is reset after every redirection. + - `maxPayload` {Number} The maximum allowed message size in bytes. Defaults to + 100 MiB (104857600 bytes). + - `maxRedirects` {Number} The maximum number of redirects allowed. Defaults + to 10. + - `origin` {String} Value of the `Origin` or `Sec-WebSocket-Origin` header + depending on the `protocolVersion`. + - `perMessageDeflate` {Boolean|Object} Enable/disable permessage-deflate. + - `protocolVersion` {Number} Value of the `Sec-WebSocket-Version` header. + - `skipUTF8Validation` {Boolean} Specifies whether or not to skip UTF-8 + validation for text and close messages. Defaults to `false`. Set to `true` + only if the server is trusted. + - Any other option allowed in [`http.request()`][] or [`https.request()`][]. + Options given do not have any effect if parsed from the URL given with the + `address` parameter. + +`perMessageDeflate` default value is `true`. When using an object, parameters +are the same of the server. The only difference is the direction of requests. +For example, `serverNoContextTakeover` can be used to ask the server to disable +context takeover. + +Create a new WebSocket instance. + +#### UNIX Domain Sockets + +`ws` supports making requests to UNIX domain sockets. To make one, use the +following URL scheme: + +``` +ws+unix:///absolute/path/to/uds_socket:/pathname?search_params +``` + +Note that `:` is the separator between the socket path and the URL path. If the +URL path is omitted + +``` +ws+unix:///absolute/path/to/uds_socket +``` + +it defaults to `/`. + +### Event: 'close' + +- `code` {Number} +- `reason` {Buffer} + +Emitted when the connection is closed. `code` is a numeric value indicating the +status code explaining why the connection has been closed. `reason` is a +`Buffer` containing a human-readable string explaining why the connection has +been closed. + +### Event: 'error' + +- `error` {Error} + +Emitted when an error occurs. Errors may have a `.code` property, matching one +of the string values defined below under [Error codes](#error-codes). + +### Event: 'message' + +- `data` {Buffer|ArrayBuffer|Buffer[]} +- `isBinary` {Boolean} + +Emitted when a message is received. `data` is the message content. `isBinary` +specifies whether the message is binary or not. + +### Event: 'open' + +Emitted when the connection is established. + +### Event: 'ping' + +- `data` {Buffer} + +Emitted when a ping is received from the server. + +### Event: 'pong' + +- `data` {Buffer} + +Emitted when a pong is received from the server. + +### Event: 'redirect' + +- `url` {String} +- `request` {http.ClientRequest} + +Emitted before a redirect is followed. `url` is the redirect URL. `request` is +the HTTP GET request with the headers queued. This event gives the ability to +inspect confidential headers and remove them on a per-redirect basis using the +[`request.getHeader()`][] and [`request.removeHeader()`][] API. The `request` +object should be used only for this purpose. When there is at least one listener +for this event, no header is removed by default, even if the redirect is to a +different domain. + +### Event: 'unexpected-response' + +- `request` {http.ClientRequest} +- `response` {http.IncomingMessage} + +Emitted when the server response is not the expected one, for example a 401 +response. This event gives the ability to read the response in order to extract +useful information. If the server sends an invalid response and there isn't a +listener for this event, an error is emitted. + +### Event: 'upgrade' + +- `response` {http.IncomingMessage} + +Emitted when response headers are received from the server as part of the +handshake. This allows you to read headers from the server, for example +'set-cookie' headers. + +### websocket.addEventListener(type, listener[, options]) + +- `type` {String} A string representing the event type to listen for. +- `listener` {Function} The listener to add. +- `options` {Object} + - `once` {Boolean} A `Boolean` indicating that the listener should be invoked + at most once after being added. If `true`, the listener would be + automatically removed when invoked. + +Register an event listener emulating the `EventTarget` interface. This method +does nothing if `type` is not one of `'close'`, `'error'`, `'message'`, or +`'open'`. + +### websocket.binaryType + +- {String} + +A string indicating the type of binary data being transmitted by the connection. +This should be one of "nodebuffer", "arraybuffer" or "fragments". Defaults to +"nodebuffer". Type "fragments" will emit the array of fragments as received from +the sender, without copyfull concatenation, which is useful for the performance +of binary protocols transferring large messages with multiple fragments. + +### websocket.bufferedAmount + +- {Number} + +The number of bytes of data that have been queued using calls to `send()` but +not yet transmitted to the network. This deviates from the HTML standard in the +following ways: + +1. If the data is immediately sent the value is `0`. +1. All framing bytes are included. + +### websocket.close([code[, reason]]) + +- `code` {Number} A numeric value indicating the status code explaining why the + connection is being closed. +- `reason` {String|Buffer} The reason why the connection is closing. + +Initiate a closing handshake. + +### websocket.isPaused + +- {Boolean} + +Indicates whether the websocket is paused. + +### websocket.extensions + +- {Object} + +An object containing the negotiated extensions. + +### websocket.onclose + +- {Function} + +An event listener to be called when connection is closed. The listener receives +a `CloseEvent` named "close". + +### websocket.onerror + +- {Function} + +An event listener to be called when an error occurs. The listener receives an +`ErrorEvent` named "error". + +### websocket.onmessage + +- {Function} + +An event listener to be called when a message is received from the server. The +listener receives a `MessageEvent` named "message". + +### websocket.onopen + +- {Function} + +An event listener to be called when the connection is established. The listener +receives an `OpenEvent` named "open". + +### websocket.pause() + +Pause the websocket causing it to stop emitting events. Some events can still be +emitted after this is called, until all buffered data is consumed. This method +is a noop if the ready state is `CONNECTING` or `CLOSED`. + +### websocket.ping([data[, mask]][, callback]) + +- `data` {Array|Number|Object|String|ArrayBuffer|Buffer|DataView|TypedArray} The + data to send in the ping frame. +- `mask` {Boolean} Specifies whether `data` should be masked or not. Defaults to + `true` when `websocket` is not a server client. +- `callback` {Function} An optional callback which is invoked when the ping + frame is written out. If an error occurs, the callback is called with the + error as its first argument. + +Send a ping. This method throws an error if the ready state is `CONNECTING`. + +### websocket.pong([data[, mask]][, callback]) + +- `data` {Array|Number|Object|String|ArrayBuffer|Buffer|DataView|TypedArray} The + data to send in the pong frame. +- `mask` {Boolean} Specifies whether `data` should be masked or not. Defaults to + `true` when `websocket` is not a server client. +- `callback` {Function} An optional callback which is invoked when the pong + frame is written out. If an error occurs, the callback is called with the + error as its first argument. + +Send a pong. This method throws an error if the ready state is `CONNECTING`. + +### websocket.protocol + +- {String} + +The subprotocol selected by the server. + +### websocket.resume() + +Make a paused socket resume emitting events. This method is a noop if the ready +state is `CONNECTING` or `CLOSED`. + +### websocket.readyState + +- {Number} + +The current state of the connection. This is one of the ready state constants. + +### websocket.removeEventListener(type, listener) + +- `type` {String} A string representing the event type to remove. +- `listener` {Function} The listener to remove. + +Removes an event listener emulating the `EventTarget` interface. This method +only removes listeners added with +[`websocket.addEventListener()`](#websocketaddeventlistenertype-listener-options). + +### websocket.send(data[, options][, callback]) + +- `data` {Array|Number|Object|String|ArrayBuffer|Buffer|DataView|TypedArray} The + data to send. +- `options` {Object} + - `binary` {Boolean} Specifies whether `data` should be sent as a binary or + not. Default is autodetected. + - `compress` {Boolean} Specifies whether `data` should be compressed or not. + Defaults to `true` when permessage-deflate is enabled. + - `fin` {Boolean} Specifies whether `data` is the last fragment of a message + or not. Defaults to `true`. + - `mask` {Boolean} Specifies whether `data` should be masked or not. Defaults + to `true` when `websocket` is not a server client. +- `callback` {Function} An optional callback which is invoked when `data` is + written out. If an error occurs, the callback is called with the error as its + first argument. + +Send `data` through the connection. This method throws an error if the ready +state is `CONNECTING`. + +### websocket.terminate() + +Forcibly close the connection.
