See http://einaros.github.com/ws for the full reports.\n\nComes with a command line utility, `wscat`, which can either act as a server (--listen), or client (--connect); Use it to debug simple websocket services.\n\n## Protocol support ##\n\n* **Hixie draft 76** (Old and deprecated, but still in use by Safari and Opera. Added to ws version 0.4.2, but server only. Can be disabled by setting the `disableHixie` option to true.)\n* **HyBi drafts 07-12** (Use the option `protocolVersion: 8`, or argument `-p 8` for wscat)\n* **HyBi drafts 13-17** (Current default, alternatively option `protocolVersion: 13`, or argument `-p 13` for wscat)\n\n_See the echo.websocket.org example below for how to use the `protocolVersion` option._\n\n## Usage ##\n\n### Installing ###\n\n`npm install ws`\n\n### Sending and receiving text data ###\n\n```js\nvar WebSocket = require('ws');\nvar ws = new WebSocket('ws://www.host.com/path');\nws.on('open', function() {\n    ws.send('something');\n});\nws.on('message', function(data, flags) {\n    // flags.binary will be set if a binary data is received\n    // flags.masked will be set if the data was masked\n});\n```\n\n### Sending binary data ###\n\n```js\nvar WebSocket = require('ws');\nvar ws = new WebSocket('ws://www.host.com/path');\nws.on('open', function() {\n    var array = new Float32Array(5);\n    for (var i = 0; i < array.length; ++i) array[i] = i / 2;\n    ws.send(array, {binary: true, mask: true});\n});\n```\n\nSetting `mask`, as done for the send options above, will cause the data to be masked according to the websocket protocol. The same option applies for text data.\n\n### Server example ###\n\n```js\nvar WebSocketServer = require('ws').Server\n  , wss = new WebSocketServer({port: 8080});\nwss.on('connection', function(ws) {\n    ws.on('message', function(message) {\n        console.log('received: %s', message);\n    });\n    ws.send('something');\n});\n```\n\n### Server sending broadcast data ###\n\n```js\nvar WebSocketServer = require('ws').Server\n  , wss = new WebSocketServer({port: 8080});\n  \nwss.broadcast = function(data) {\n\tfor(var i in this.clients)\n\t\tthis.clients[i].send(data);\n};\n```\n\n### Error handling best practices ###\n\n```js\n// If the WebSocket is closed before the following send is attempted\nws.send('something');\n\n// Errors (both immediate and async write errors) can be detected in an optional callback.\n// The callback is also the only way of being notified that data has actually been sent.\nws.send('something', function(error) {\n    // if error is null, the send has been completed,\n    // otherwise the error object will indicate what failed.\n});\n\n// Immediate errors can also be handled with try/catch-blocks, but **note**\n// that since sends are inherently asynchronous, socket write failures will *not*\n// be captured when this technique is used.\ntry {\n    ws.send('something');\n}\ncatch (e) {\n    // handle error\n}\n```\n\n### echo.websocket.org demo ###\n\n```js\nvar WebSocket = require('ws');\nvar ws = new WebSocket('ws://echo.websocket.org/', {protocolVersion: 8, origin: 'http://websocket.org'});\nws.on('open', function() {\n    console.log('connected');\n    ws.send(Date.now().toString(), {mask: true});\n});\nws.on('close', function() {\n    console.log('disconnected');\n});\nws.on('message', function(data, flags) {\n    console.log('Roundtrip time: ' + (Date.now() - parseInt(data)) + 'ms', flags);\n    setTimeout(function() {\n        ws.send(Date.now().toString(), {mask: true});\n    }, 500);\n});\n```\n\n### wscat against echo.websocket.org ###\n\n    $ npm install -g ws\n    $ wscat -c ws://echo.websocket.org -p 8\n    connected (press CTRL+C to quit)\n    > hi there\n    < hi there\n    > are you a happy parrot?\n    < are you a happy parrot?\n\n### Other examples ###\n\nFor a full example with a browser client communicating with a ws server, see the examples folder.\n\nNote that the usage together with Express 3.0 is quite different from Express 2.x. The difference is expressed in the two different serverstats-examples.\n\nOtherwise, see the test cases.\n\n### Running the tests ###\n\n`make test`\n\n## API Docs ##\n\nSee the doc/ directory for Node.js-like docs for the ws classes.\n\n## License ##\n\n(The MIT License)\n\nCopyright (c) 2011 Einar Otto Stangvik &lt;einaros@gmail.com&gt;\n\nPermission is hereby granted, free of charge, to any person obtaining\na copy of this software and associated documentation files (the\n'Software'), to deal in the Software without restriction, including\nwithout limitation the rights to use, copy, modify, merge, publish,\ndistribute, sublicense, and/or sell copies of the Software, and to\npermit persons to whom the Software is furnished to do so, subject to\nthe following conditions:\n\nThe above copyright notice and this permission notice shall be\nincluded in all copies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED 'AS IS', WITHOUT WARRANTY OF ANY KIND,\nEXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF\nMERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.\nIN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY\nCLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT,\nTORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE\nSOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.\n",
