Socket.IO-connect Connect WebSocket Middleware Wrapper Around Socket.IO-node

Leverage the power of Connect middleware from Socket.IO-node.

Installation

npm install socket.io-connect

How To Use

Method 1:

var connect = require('connect')

  // Setup your server with middleware
  , server = connect.createServer(
      connect.cookieParser(),
      connect.session({ secret: "your secret", fingerprint: "" })
    )
  , io = require('socket.io-connect');

server.listen(8000); // Listen for requests

var socket = io.listen(server); // Wrap your connect server with Socket.IO

// socket.prefixWithMiddleware punts the client's request down
// the Connect middleware if there is a Socket.IO 'connection' event
socket.on('connection', socket.prefixWithMiddleware( function (client, req, res) {
  console.log(req.session); // Access to the session!!!!
}));

// If there's no 'connection' event, then the request gets passed to
// the regular middleware

Method 2:

var connect = require('connect')
  , socketIOconnect = require("socket.io-connect").socketIOconnect;

// Setup your server with middleware
var server = connect.createServer(
      // socketIOconnect "middleware" does the same as Method 1 but more idiomatically
      // Always have socketIO middleware come first, so it can setup the socket.IO endpoint
      socketIOconnect( function () { return server; }, function (client, req, res) {
        client.send(req.session.toString()); // Send the client their session
      }),
      connect.cookieParser(),
      connect.session({ secret: "your secret", fingerprint: "" })
    );

server.listen(8000); // Listen for requests

Example

I have re-implemented the example chat application from the Socket.IO-node github repo, using Connect and Socket.IO-connect.

To run this example using method 1:

git clone http://github.com/bnoguchi/Socket.IO-connect.git --recursive
cd Socket.IO-connect/example/
node server1.js

To run this example using method 2:

git clone http://github.com/bnoguchi/Socket.IO-connect.git --recursive
cd Socket.IO-connect/example/
node server2.js

and then point your browser to http://127.0.0.1:8080.
