Building Real-Time Laravel Apps with Pusher

Using Laravel Event Broadcasting

By using Laravel 5.1 you already have the Pusher library integrated into your application so there's no installation required. We've already done all the set up we need when we set our environment variables.

The Pusher Event Broadcaster is configured in config/broadcasting.php. Luckily it's the default broadcaster so we don't actually need to configure anything.

Laravel 5.1 comes with an in-built Pusher Event Broadcaster that we're going to use. To use this we need to follow a few conventions.

Firstly, we need to define a class that represents our event. For simplicity we'll add this directly to app/Http/routes.php for now.

use Illuminate\Contracts\Broadcasting\ShouldBroadcast;

class TestEvent implements ShouldBroadcast
    public $text;

    public function __construct($text)
        $this->text = $text;

    public function broadcastOn()
        return ['test-channel'];

As with the previous example, we'll go in to the details of channels and events in a later exercise.

Next, update the contents of the app/Http/routes.php file with the following:

get('/broadcast', function() {
    event(new TestEvent('Broadcasting in Laravel using Pusher!'));

    return view('welcome');

As before, to test:

  1. Open up the Pusher Debug Console for your Pusher application
  2. Ensure your Laravel application is running (php artisan serve)
  3. In a new browser tab or window, navigate to the /broadcast route in the Laravel app (or simply refresh your tab), http://localhost:8000/broadcast

Again, you'll see the event appear in the Pusher Debug Console. It's working!

It's not working! Oh no, Something has gone wrong. Don't worry, we'll work out what's happening in an upcoming section on Debugging your server-side integration with Pusher.

When things don't work as expected it's really useful to be able to debug your server-side integration with Pusher.
