How to use websocket client in laravel?

1. First, you need to install the pusher/pusher-php-server package in your Laravel project by running the following command in your terminal:

1

composer require pusher/pusher-php-server

1. Next, you need to set up a Pusher account and get your Pusher keys (app_id, app_key, app_secret, cluster). You can do this by signing up at https://pusher.com/.
2. Once you have your Pusher keys, you can configure them in your Laravel project by adding the following values to your .env file:

1
2
3
4

PUSHER_APP_ID=your_pusher_app_id
PUSHER_APP_KEY=your_pusher_app_key
PUSHER_APP_SECRET=your_pusher_app_secret
PUSHER_APP_CLUSTER=your_pusher_app_cluster

1. Next, you need to configure the Pusher service in Laravel by editing the config/broadcasting.php file. Add the following configuration to the connections array:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

'pusher' => [
    'driver' => 'pusher',
    'key' => env('PUSHER_APP_KEY'),
    'secret' => env('PUSHER_APP_SECRET'),
    'app_id' => env('PUSHER_APP_ID'),
    'options' => [
        'cluster' => env('PUSHER_APP_CLUSTER'),
        'encrypted' => true,
    ],
],

1. After configuring Pusher in Laravel, you can start using websockets in your Laravel application. You can create an event that will trigger the websocket connection and broadcast a message to a specified channel. Here is an example of creating an event:

1

php artisan make:event WebSocketEvent

1. In the generated WebSocketEvent class, you can define the logic to broadcast a message to a channel. For example:

1
2
3
4
5
6
7
8
9

public function broadcastOn()
{
    return new Channel('channel-name');
}

public function broadcastWith()
{
    return ['message' => 'Hello, World!'];
}

1. You can then trigger the event from your controller or any other part of your application where you want to broadcast the message using the following code:

1

event(new WebSocketEvent());

1. Finally, you can listen for the websocket events in your front-end application using Pusher.js or any other websocket client library. Check the Pusher documentation for more information on how to set up the client-side script to listen for events.

That's it! You have now successfully set up and used a websocket client in your Laravel application.
