WHATʼS NEW IN 0.7THE LESSONS WE LEARNED FROM 0.6

COMPLETE API REWRITE

var io = require(ʻsocket.ioʼ) , http = require(ʻhttpʼ);var s = http.createServer(function(q,r){r.writeHead(200);r.end(ʻsupʼ)});s.listen(80)io.listen(s); // uses existing server

var io = require(ʻsocket.ioʼ) , http = require(ʻhttpʼ);var s = http.createServer(function(q,r){r.writeHead(200);r.end(ʻsupʼ)});s.listen(80)io.listen(s); // uses existing servervar io = require(ʻsocket.ioʼ);io.listen(80); // creates one for us

var io = require(ʻsocket.ioʼ).listen();// express styled conﬁgurationio.conﬁgure(ʻdevelopmentʼ, function(){ io.set(ʻlog levelʼ, 3);});

MULTIPLEPROCESSES

NEW PROTOCOL

MESSAGE FLAGS FIRE AND FORGET, JSON NEW PROTOCOL

io.sockets.on(ʻconnectionʼ, function (socket) { socket.volatile.send(ʻpew pewʼ); socket.json.send([{nodecamp:ʻftwʼ}]);}; NEW PROTOCOL

ACKNOWLEDGEMENTS BETWEEN CLIENT & SERVER, SERVER & CLIENT NEW PROTOCOL

// server sideio.sockets.on(ʻconnectionʼ, function (socket) { socket.send(ʻbyeʼ, function () { // ack });});// client sidevar socket = io.connect();socket.send(ʻhiʼ, function () { // ack}); NEW PROTOCOL

NAMESPACING MULTIPLEXING NEW PROTOCOL

// server sideio.sockets.on(ʻconnectionʼ, function (socket) { socket.send(ʻbyeʼ, function () { // ack });});// client sidevar socket = io.connect();socket.send(ʻhiʼ, function () { // ack}); NEW PROTOCOL

HANDSHAKINGFUCK YEAH, SESSIONS SUPPORT NEW PROTOCOL

EVENTS NEW PROTOCOL
