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

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);

Example - Secure WebSocket server

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);
