node_webstream

• Simple TCP style communication with the browser using websockets or long polling.
• jQuery client
• No handshaking, sessions, channels: build what you want

Todo

• Streaming support instead of just long polling.
• Better error handling (in many situations just any error handling).
• More examples (a channels example? node_chat type example)

Usage

See example folder for a working example

Server side (Node)

Based on TCP in node.

// Server
var webstream = require("./lib/webstream");
webstream.createServer(function (user) {
user.addListener('connect', function () {
// User connected
// Send data to user
user.write(string);
});
user.addListener('data', function (data) {
// Incoming data
});
user.addListener('close', function () {
// User lost
});
});
// Attach to HTTP and WebSocket servers
http.createServer(function (req, res) {
testWebStream.httpReq(req, res);
}).listen(8001);
// Use http://github.com/Guille/node.websocket.js for websockets
var ws = require("./lib/deps/ws");
ws.createServer(function (websocket) {
testWebStream.wsReq(websocket);
}).listen(8002);

Client side (jQuery)

Based on ajax request in jquery

var stream = $.webstream({
// URL for websocket server
webSocket: 'ws://localhost:8002',
// Relative URL for http server
http: '/webstream',
open: function () {
// Connected to server
},
data: function (data) {
// Data from server
},
close: function () {
// Lost connection
},
error: function () {
// Error with connection
}
});
// Write to stream
stream.write(string);
