Minimal WebSockets for node.js

• Compatible with node v0.1.91
• Interface is almost the same as tcp.createServer(...)
• Flash policy file requests are handled (hardcoded, permissive), see http://github.com/gimite/web-socket-js

Example - WebSocket server

<pre><code> var sys = require("sys"), ws = require("./ws"); ws.createServer(function (websocket) { websocket.addListener("connect", function (resource) { // emitted after handshake sys.debug("connect: " + resource); // server closes connection after 10s, will also get "close" event setTimeout(websocket.end, 10 * 1000); }).addListener("data", function (data) { // handle incoming data sys.debug(data); // send data to client websocket.write("Thanks!"); }).addListener("close", function () { // emitted when server or client closes connection sys.debug("close"); }); }).listen(8080); </code></pre>

Example - Secure WebSocket server

<pre><code> var sys = require("sys"), ws = require("./ws"), crypto = require('crypto'), fs = require("fs"); var privateKey = fs.readFileSync('privatekey.pem').toString(); var certificate = fs.readFileSync('certificate.pem').toString(); var credentials = crypto.createCredentials({key: privateKey, cert: certificate}); ws.createSecureServer(function (websocket) { websocket.addListener("connect", function (resource) { // emitted after handshake sys.debug("connect: " + resource); // server closes connection after 10s, will also get "close" event setTimeout(websocket.end, 10 * 1000); }).addListener("data", function (data) { // handle incoming data sys.debug(data); // send data to client websocket.write("Thanks!"); }).addListener("close", function () { // emitted when server or client closes connection sys.debug("close"); }); }, credentials).listen(8080); </code></pre>
