websocket
is a simple wrapper around tcp.createServer that abstracts away the details of a browser WebSocket. It's designed to be a drop in replacement for a regular TCP server, but be accessible from a browser that supports WebSocket.
var websocket = require("websocket");
var server = websocket.createServer(function (socket) {
socket.write("hello\r\n");
socket.addListener("data", function (data) {
socket.write(data);
});
socket.addListener("end", function () {
socket.write("goodbye\r\n");
socket.end();
});
});
server.listen(7000, "localhost");
This implementation is quick and dirty and skips over a lot of details. For example it doesn't validate any of the same origin stuff.
For a more fleshed out implementation, but with a larger api, please see http://github.com/guille/node.websocket.js/
