| # node-websocket-server # | ||
|
|
||
| This is a server for the WebSocket Protocol. It currently to works | ||
| with both [draft75](http://tools.ietf.org/html/draft-hixie-thewebsocketprotocol-75) and [draft76](http://www.whatwg.org/specs/web-socket-protocol/) of the protocol specification. | ||
|
|
||
| ## Compatibility ## | ||
|
|
||
| This module is known to work with Node.js v0.1.98. May also work on Node.js greater than v0.1.94, dependent on protocol version being used. | ||
|
|
||
| It has been reported that this module experiences some issues on solaris and ubuntu systems, so far these issues are unresolved, but seem to be related to the core of Node.js | ||
|
|
||
| ## Synopsis ## | ||
|
|
||
| An example of a simple server that will echo the messages received back out can be found in `examples/echo-server.js`, coupled with a websocket client like the `examples/client.html`, and you have a working websocket client/server. | ||
|
|
||
| ## Server ## | ||
|
|
||
| The server acts like a normal http server in many respects, and exposes much of node's http.Server events and | ||
| methods. However, there are a few differences, and things that haven't yet been implemented. | ||
|
|
||
| `ws.creareServer()` returns an instance of `ws.Server`, which acts like `http.Server`. However, not all methods | ||
| and events that act on `http.Server` will act on `ws.Server`. Your application can handle normal http requests by listening for the "request" event. | ||
|
|
||
| `ws.createServer()` and `ws.Server()` takes an options object as its only parameter. The options object has a these | ||
| defaults: | ||
|
|
||
| { debug: false, // Boolean: Show debug information. | ||
| , version: "auto" // String: Value must be either: draft75, draft76, auto | ||
| , origin: "*" // String, Array: A match for a valid connection origin | ||
| , subprotocol: null // String, Array: A match for a valid connection subprotocol. | ||
| } | ||
|
|
||
| After a websocket client connects to the server, the server will emit the `'connection'` event, with the `ws/connection` | ||
| instance for the connection. This means that the connection has undertaken the necessary websocket handshaking and | ||
| is now ready to send and receive data. | ||
|
|
||
| **NOTE:** Currently the origin and subprotocols are not strictly checked, this will be added in future versions. | ||
|
|
||
| ### server.listen(port, host) ### | ||
|
|
||
| The same as the `http.Server` listen method. | ||
|
|
||
| ### server.send(client_id, message) ### | ||
|
|
||
| Sends `message` to the client with `id` of `client_id`. | ||
|
|
||
| ### server.broadcast(message) ### | ||
|
|
||
| Sends `message` to all connected clients. | ||
|
|
||
| ### server.close() ### | ||
|
|
||
| The same as the `http.Server` close method. | ||
|
|
||
| ### Event: listening ### | ||
|
|
||
| `function () { }` | ||
|
|
||
| Emits when the server is ready to start accepting clients, after `listen` has been called. | ||
|
|
||
| ### Event: connection ### | ||
|
|
||
| `function (connection) { }` | ||
|
|
||
| Emits when a websocket client connects to the server. The `connection` is an instance of `ws/connection`. | ||
|
|
||
| ### Event: request ### | ||
|
|
||
| `function (request, response) { }` | ||
|
|
||
| Emits when a client connects using standard HTTP to the server. | ||
| This is the same as the `http.Server` `request` event. | ||
| Use this to handle normal http connections that won't upgrade to WebSocket. | ||
|
|
||
| ### Event: stream ### | ||
|
|
||
| `function (stream) { }` | ||
|
|
||
| The same as the `http.Server` `stream` event. | ||
|
|
||
| ### Event: shutdown ### | ||
|
|
||
| `function (errno) { }` | ||
|
|
||
| Emits when the server is closed. Proxied from `http.Server` | ||
|
|
||
| ### Event: close ### | ||
|
|
||
| `function(connection) { }` | ||
|
|
||
| Emits when a websocket client's connection closes. The `connection` is an instance of `ws/connection`. | ||
|
|
||
| ## ws/connection ## | ||
|
|
||
| This is an instance of a client connecting to the `ws.Server`, this is similar to the `req` on a `http.Server`. | ||
|
|
||
| ### connecting.getVersion() ### | ||
|
|
||
| Returns the websocket specification version that the connection is using. | ||
|
|
||
| ### connection.write(data) ### | ||
|
|
||
| Publishes a message to the client. | ||
|
|
||
| ### connection.close() ### | ||
|
|
||
| Closes the client's connection. | ||
|
|
||
| ### connection.reject(reason) ### | ||
|
|
||
| Rejects a client's connection. `reason` is only used when the server is in debug mode. | ||
|
|
||
| ### connection.handshake() ### | ||
|
|
||
| This carries out handshaking with a client, this method is semi-private. | ||
|
|
||
| ### Event: stateChange ### | ||
|
|
||
| `function (state, previous_state) { }` | ||
|
|
||
| Each time the connection's status changes this is emitted, the state codes are: | ||
|
|
||
| 0. unknown | ||
| 1. opening | ||
| 2. waiting | ||
| 3. handshaking | ||
| 4, connected | ||
| 5. closed | ||
| A state of `2` should never be reached, if it is, please do let me know. | ||
|
|
||
| ### Event: message ### | ||
|
|
||
| `function (message) { }` | ||
|
|
||
| Emits when a client sends a message to the server. | ||
|
|
||
| ### Event: close ### | ||
|
|
||
| `function () { }` | ||
|
|
||
| Emits when a connection is closes. | ||
|
|
||
| ### Event: rejected ### | ||
|
|
||
| `function () { }` | ||
|
|
||
| Emits when a connection is rejected by the server, usually for a bad handshake or version mismatch. This event is immediately followed by the `close` event | ||
