+# websocket-driver [![Build Status](https://travis-ci.org/faye/websocket-driver-node.svg)](https://travis-ci.org/faye/websocket-driver-node)
+
+This module provides a complete implementation of the WebSocket protocols that
+can be hooked up to any I/O stream. It aims to simplify things by decoupling the
+protocol details from the I/O layer, such that users only need to implement code
+to stream data in and out of it without needing to know anything about how the
+protocol actually works. Think of it as a complete WebSocket system with
+pluggable I/O.
+
+Due to this design, you get a lot of things for free. In particular, if you hook
+this module up to some I/O object, it will do all of this for you:
+
+- Select the correct server-side driver to talk to the client
+- Generate and send both server- and client-side handshakes
+- Recognize when the handshake phase completes and the WS protocol begins
+- Negotiate subprotocol selection based on `Sec-WebSocket-Protocol`
+- Negotiate and use extensions via the
+  [websocket-extensions](https://github.com/faye/websocket-extensions-node)
+  module
+- Buffer sent messages until the handshake process is finished
+- Deal with proxies that defer delivery of the draft-76 handshake body
+- Notify you when the socket is open and closed and when messages arrive
+- Recombine fragmented messages
+- Dispatch text, binary, ping, pong and close frames
+- Manage the socket-closing handshake process
+- Automatically reply to ping frames with a matching pong
+- Apply masking to messages sent by the client
+
+This library was originally extracted from the [Faye](http://faye.jcoglan.com)
+project but now aims to provide simple WebSocket support for any Node-based
+project.
+
+
+## Installation
+
+```
+$ npm install websocket-driver
+```
+
+
+## Usage
+
+This module provides protocol drivers that have the same interface on the server
+and on the client. A WebSocket driver is an object with two duplex streams
+attached; one for incoming/outgoing messages and one for managing the wire
+protocol over an I/O stream. The full API is described below.
+
+
+### Server-side with HTTP
+
+A Node webserver emits a special event for 'upgrade' requests, and this is where
+you should handle WebSockets. You first check whether the request is a
+WebSocket, and if so you can create a driver and attach the request's I/O stream
+to it.
+
+```js
+var http = require('http'),
+    websocket = require('websocket-driver');
+
+var server = http.createServer();
+
+server.on('upgrade', function(request, socket, body) {
+  if (!websocket.isWebSocket(request)) return;
+
+  var driver = websocket.http(request);
+
+  driver.io.write(body);
+  socket.pipe(driver.io).pipe(socket);
+
+  driver.messages.on('data', function(message) {
+    console.log('Got a message', message);
+  });
+
+  driver.start();
+});
+```
+
+Note the line `driver.io.write(body)` - you must pass the `body` buffer to the
+socket driver in order to make certain versions of the protocol work.
+
+
+### Server-side with TCP
+
+You can also handle WebSocket connections in a bare TCP server, if you're not
+using an HTTP server and don't want to implement HTTP parsing yourself.
+
+The driver will emit a `connect` event when a request is received, and at this
+point you can detect whether it's a WebSocket and handle it as such. Here's an
+example using the Node `net` module:
+
+```js
+var net = require('net'),
+    websocket = require('websocket-driver');
+
+var server = net.createServer(function(connection) {
+  var driver = websocket.server();
+
+  driver.on('connect', function() {
+    if (websocket.isWebSocket(driver)) {
+      driver.start();
+    } else {
+      // handle other HTTP requests
+    }
+  });
+
+  driver.on('close', function() { connection.end() });
+  connection.on('error', function() {});
+
+  connection.pipe(driver.io).pipe(connection);
+
+  driver.messages.pipe(driver.messages);
+});
+
+server.listen(4180);
+```
+
+In the `connect` event, the driver gains several properties to describe the
+request, similar to a Node request object, such as `method`, `url` and
+`headers`. However you should remember it's not a real request object; you
+cannot write data to it, it only tells you what request data we parsed from the
+input.
+
+If the request has a body, it will be in the `driver.body` buffer, but only as
+much of the body as has been piped into the driver when the `connect` event
+fires.
+
+
+### Client-side
+
+Similarly, to implement a WebSocket client you just need to make a driver by
+passing in a URL. After this you use the driver API as described below to
+process incoming data and send outgoing data.
+
+
+```js
+var net = require('net'),
+    websocket = require('websocket-driver');
+
+var driver = websocket.client('ws://www.example.com/socket'),
+    tcp = net.connect(80, 'www.example.com');
+
+tcp.pipe(driver.io).pipe(tcp);
+
+tcp.on('connect', function() {
+  driver.start();
+});
+
+driver.messages.on('data', function(message) {
+  console.log('Got a message', message);
+});
+```
+
+Client drivers have two additional properties for reading the HTTP data that was
+sent back by the server:
+
+- `driver.statusCode` - the integer value of the HTTP status code
+- `driver.headers` - an object containing the response headers
+
+
+### HTTP Proxies
+
+The client driver supports connections via HTTP proxies using the `CONNECT`
+method. Instead of sending the WebSocket handshake immediately, it will send a
+`CONNECT` request, wait for a `200` response, and then proceed as normal.
+
+To use this feature, call `driver.proxy(url)` where `url` is the origin of the
+proxy, including a username and password if required. This produces a duplex
+stream that you should pipe in and out of your TCP connection to the proxy
+server. When the proxy emits `connect`, you can then pipe `driver.io` to your
+TCP stream and call `driver.start()`.
+
+```js
+var net = require('net'),
+    websocket = require('websocket-driver');
+
+var driver = websocket.client('ws://www.example.com/socket'),
+    proxy  = driver.proxy('http://username:password@proxy.example.com'),
+    tcp    = net.connect(80, 'proxy.example.com');
+
+tcp.pipe(proxy).pipe(tcp, { end: false });
+
+tcp.on('connect', function() {
+  proxy.start();
+});
+
+proxy.on('connect', function() {
+  driver.io.pipe(tcp).pipe(driver.io);
+  driver.start();
+});
+
+driver.messages.on('data', function(message) {
+  console.log('Got a message', message);
+});
+```
+
+The proxy's `connect` event is also where you should perform a TLS handshake on
+your TCP stream, if you are connecting to a `wss:` endpoint.
+
+In the event that proxy connection fails, `proxy` will emit an `error`. You can
+inspect the proxy's response via `proxy.statusCode` and `proxy.headers`.
+
+```js
+proxy.on('error', function(error) {
+  console.error(error.message);
+  console.log(proxy.statusCode);
+  console.log(proxy.headers);
+});
+```
+
+Before calling `proxy.start()` you can set custom headers using
+`proxy.setHeader()`:
+
+```js
+proxy.setHeader('User-Agent', 'node');
+proxy.start();
+```
+
+
+### Driver API
+
+Drivers are created using one of the following methods:
+
+```js
+driver = websocket.http(request, options)
+driver = websocket.server(options)
+driver = websocket.client(url, options)
+```
+
+The `http` method returns a driver chosen using the headers from a Node HTTP
+request object. The `server` method returns a driver that will parse an HTTP
+request and then decide which driver to use for it using the `http` method. The
+`client` method always returns a driver for the RFC version of the protocol with
+masking enabled on outgoing frames.
+
+The `options` argument is optional, and is an object. It may contain the
+following fields:
+
+- `maxLength` - the maximum allowed size of incoming message frames, in bytes.
+  The default value is `2^26 - 1`, or 1 byte short of 64 MiB.
+- `protocols` - an array of strings representing acceptable subprotocols for use
+  over the socket. The driver will negotiate one of these to use via the
+  `Sec-WebSocket-Protocol` header if supported by the other peer.
+
+A driver has two duplex streams attached to it:
+
+- **`driver.io`** - this stream should be attached to an I/O socket like a TCP
+  stream. Pipe incoming TCP chunks to this stream for them to be parsed, and
+  pipe this stream back into TCP to send outgoing frames.
+- **`driver.messages`** - this stream emits messages received over the
+  WebSocket.  Writing to it sends messages to the other peer by emitting frames
+  via the `driver.io` stream.
+
+All drivers respond to the following API methods, but some of them are no-ops
+depending on whether the client supports the behaviour.
+
+Note that most of these methods are commands: if they produce data that should
+be sent over the socket, they will give this to you by emitting `data` events on
+the `driver.io` stream.
+
+#### `driver.on('open', function(event) {})`
+
+Adds a callback to execute when the socket becomes open.
+
+#### `driver.on('message', function(event) {})`
+
+Adds a callback to execute when a message is received. `event` will have a
+`data` attribute containing either a string in the case of a text message or a
+`Buffer` in the case of a binary message.
+
+You can also listen for messages using the `driver.messages.on('data')` event,
+which emits strings for text messages and buffers for binary messages.
+
+#### `driver.on('error', function(event) {})`
+
+Adds a callback to execute when a protocol error occurs due to the other peer
+sending an invalid byte sequence. `event` will have a `message` attribute
+describing the error.
+
+#### `driver.on('close', function(event) {})`
+
+Adds a callback to execute when the socket becomes closed. The `event` object
+has `code` and `reason` attributes.
+
+#### `driver.on('ping', function(event) {})`
+
+Adds a callback block to execute when a ping is received. You do not need to
+handle this by sending a pong frame yourself; the driver handles this for you.
+
+#### `driver.on('pong', function(event) {})`
+
+Adds a callback block to execute when a pong is received. If this was in
+response to a ping you sent, you can also handle this event via the
+`driver.ping(message, function() { ... })` callback.
+
+#### `driver.addExtension(extension)`
+
+Registers a protocol extension whose operation will be negotiated via the
+`Sec-WebSocket-Extensions` header. `extension` is any extension compatible with
+the [websocket-extensions](https://github.com/faye/websocket-extensions-node)
+framework.
+
+#### `driver.setHeader(name, value)`
+
+Sets a custom header to be sent as part of the handshake response, either from
+the server or from the client. Must be called before `start()`, since this is
+when the headers are serialized and sent.
+
+#### `driver.start()`
+
+Initiates the protocol by sending the handshake - either the response for a
+server-side driver or the request for a client-side one. This should be the
+first method you invoke.  Returns `true` if and only if a handshake was sent.
+
+#### `driver.parse(string)`
+
+Takes a string and parses it, potentially resulting in message events being
+emitted (see `on('message')` above) or in data being sent to `driver.io`.  You
+should send all data you receive via I/O to this method by piping a stream into
+`driver.io`.
+
+#### `driver.text(string)`
+
+Sends a text message over the socket. If the socket handshake is not yet
+complete, the message will be queued until it is. Returns `true` if the message
+was sent or queued, and `false` if the socket can no longer send messages.
+
+This method is equivalent to `driver.messages.write(string)`.
+
+#### `driver.binary(buffer)`
+
+Takes a `Buffer` and sends it as a binary message. Will queue and return `true`
+or `false` the same way as the `text` method. It will also return `false` if the
+driver does not support binary messages.
+
+This method is equivalent to `driver.messages.write(buffer)`.
+
+#### `driver.ping(string = '', function() {})`
+
+Sends a ping frame over the socket, queueing it if necessary. `string` and the
+callback are both optional. If a callback is given, it will be invoked when the
+socket receives a pong frame whose content matches `string`. Returns `false` if
+frames can no longer be sent, or if the driver does not support ping/pong.
+
+#### `driver.pong(string = '')`
+
+Sends a pong frame over the socket, queueing it if necessary. `string` is
+optional. Returns `false` if frames can no longer be sent, or if the driver does
+not support ping/pong.
+
+You don't need to call this when a ping frame is received; pings are replied to
+automatically by the driver. This method is for sending unsolicited pongs.
+
+#### `driver.close()`
+
+Initiates the closing handshake if the socket is still open. For drivers with no
+closing handshake, this will result in the immediate execution of the
+`on('close')` driver. For drivers with a closing handshake, this sends a closing
+frame and `emit('close')` will execute when a response is received or a protocol
+error occurs.
+
+#### `driver.version`
+
+Returns the WebSocket version in use as a string. Will either be `hixie-75`,
+`hixie-76` or `hybi-$version`.
+
+#### `driver.protocol`
+
+Returns a string containing the selected subprotocol, if any was agreed upon
+using the `Sec-WebSocket-Protocol` mechanism. This value becomes available after
+`emit('open')` has fired.

+Streams in a WebSocket connection
+---------------------------------

+
+Message transfer in each direction is simple: IO receives a byte stream [1] and
+sends this stream for parsing. The parser will periodically emit a complete
+message text on the Messages stream [2]. Similarly, when messages are written
+to the Messages stream [3], they are framed using the WebSocket wire format and
+emitted via IO [4].
+
+There is a feedback loop via [5] since some input from [1] will be things like
+ping, pong and close frames. In these cases the protocol responds by emitting
+responses directly back to [4] rather than emitting messages via [2].
+
+For the purposes of flow control, we consider the sources of each Readable
+stream to be as follows:
+
+* [2] receives input from [1]
+* [4] receives input from [1] and [3]
+
+The classes below express the relationships described above without prescribing
+anything about how parse() and frame() work, other than assuming they emit
+'data' events to the IO and Messages streams. They will work with any protocol
+driver having these two methods.
