Generic Socket Events

A set of generic events for sending and receiving json objects through socket.io.

Allows you to easily announce, broadcast and directly send data to other sockets, and also join/leave rooms through a basic client-side API.

Setup

NPM

$ npm install gsockets

Server

var gsockets = require('gsockets');

// to enable debug logs, add this line
gsockets.config({ log: true});

// express middleware to host the client.js file at /gsockets/client.js
app.use(gsockets.client);

Using existing Socket.IO

io.on('connect', function(socket){
	gsockets.bind(io, socket);
});

Using standalone mode

// choose whatever port number you want to use
gsockets.listen(1234);

Client

<script src="https://cdn.socket.io/socket.io-1.0.6.js"></script>
<script src="/gsockets/client.js"></script>
<script>
	gsockets.connect();

	gsockets.broadcast('user_connected');

	gsockets.on('user_connected', function(){
		console.log('A user has connected');
	});
</script>

Server API

gsockets.client(req, res, next)

Serve the client.js file at the url /gsockets/client.js

• usage: app.use(gsockets.client);

gsockets.config(obj)

Modify configuration settings of gsockets. The only option currently available is log.

• usage: gsockets.config({ log: true});

gsockets.bind(io, socket)

Add the gsockets events to your socket.io server

gsockets.listen(port)

Create a separate instance of socket.io especially to run gsockets.

Client API

Create the connection to the socket.io server

• ip (optional) The ip of the server if different from the current page

• usage: var socketID = gsockets.socket.id;

gsockets.on(event, callback)

Run the callback when an event is emited from the server

• event The name of the event to listen for
• callback The function to run when this event is fired

gsockets.onDisconnect(callback)

Run the callback when a socket disconnects

• callback The function to run when this event is fired

gsockets.announce(event, [data])

Emit event to all sockets

• event The name of the event that will be sent to another client
• data (optional) Data object

gsockets.bounce(event, [data])

Emit event to this socket

• event The name of the event that will be sent to another client
• data (optional) Data object

gsockets.send(socketID, event, [data])

Emit event to specific socket
