BrainSocket.js

WebSockets for realtime event-driven js apps.

This js library is a helper class that pairs nicely with the BrainSocket.php Laravel package.

Load the script into your app:

<script type="text/javascript" src="js/brain-socket.min.js" />

Create the BrainSocket object:

window.app = {};

app.BrainSocket = new BrainSocket(
		new WebSocket('ws://localhost:8080'),
		new BrainSocketPubSub()
);

The class requires 2 parameters to get up an running:

The first is the WebSocket object which should point to a WebSocket server.
The second is the BrainSocketPubSub class (you can feel free to implement your own just make sure you pass in an object with the forget, listen and fire methods).

Note: If you are using our BrainSocket.php package you should see "Connection Established!" messages in the terminal window running your WebSocket server when you load your js app in a browser.

Next we can start subscribing to some custom BrainSocket events via Event.listen.

app.BrainSocket.Event.listen('some.event',function(msg)
{
	console.log(msg);
});

app.BrainSocket.Event.listen('app.success',function(msg)
{
	console.log(msg);
});

app.BrainSocket.Event.listen('app.error',function(msg)
{
	console.log(msg);
});

Note: The msg parameter passed into the event listener is a POJO (Plain Old Javascript Object) that contains client and possibly server objects (also POJOs), which contain the original client data and any server data that was passed back.

Note: The app.success and app.error events are not required but are helper events for dealing with flash messaging.

To fire an event to the WebSocket server you can call:

app.BrainSocket.message('some.event',[some:data]);

Typically you would fire these messages after user interactions take place in your app.

Here's an example with jquery:

$('button.user-signup').click(function(event)
{

	if(something.happens)
	{
		app.BrainSocket.success('Congrats, Welcome to the team!');
	}else
	{
		app.BrainSocket.error('We\'re sorry, there was an error with your submission.');
	}

	return false;

});

And that's it!
