How to Build Real-Time Features with Laravel and WebSockets?

Diving into the world of real-time features with Laravel and WebSockets, nice choice! Laravel makes it pretty smooth, and WebSockets adds that extra dash of interactivity. Now we can discuss How to Build Real-Time Features with Laravel and WebSockets?

Building real-time features with Laravel and WebSockets involves a few key steps. Here’s a general guide to help you get started:

Install Laravel WebSockets Package:

composer require beyondcode/laravel-websockets

Publish Configuration and Run Migrations:

php artisan vendor:publish --provider="BeyondCode\LaravelWebSockets\WebSocketsServiceProvider" --tag="migrations"
php artisan migrate

Configure Broadcasting:

Update .env:

BROADCAST_DRIVER=pusher

Install Pusher:

composer require pusher/pusher-php-server

Configure Pusher:

Add your Pusher credentials to the .env file:

PUSHER_APP_ID=your-app-id
PUSHER_APP_KEY=your-app-key
PUSHER_APP_SECRET=your-app-secret
PUSHER_APP_CLUSTER=your-app-cluster

Configure Laravel Echo:

Install Laravel Echo and Pusher JS:

npm install --save laravel-echo pusher-js

Bootstrap Echo in resources/js/bootstrap.js:

import Echo from "laravel-echo";
window.Pusher = require('pusher-js');
window.Echo = new Echo({
    broadcaster: 'pusher',
    key: process.env.MIX_PUSHER_APP_KEY,
    cluster: process.env.MIX_PUSHER_APP_CLUSTER,
    encrypted: true,
});

Create a WebSocket Event:

Generate an event that implements the ShouldBroadcast interface:

php artisan make:event MyEvent

Modify the generated event class (MyEvent.php) to broadcast on a channel:

class MyEvent implements ShouldBroadcast
{
    public $data;

    public function __construct($data)
    {
        $this->data = $data;
    }

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

Broadcasting Events:

Trigger the event where you want it to be broadcasted:

event(new MyEvent($someData));

Subscribe to the Channel:

In your frontend, subscribe to the channel and listen for events:

Echo.channel('my-channel')
.listen('MyEvent', (e) => {
console.log(e.data);
// Handle the event data
});

Run WebSocket Server:

Start the Laravel WebSockets server:

php artisan websockets:serve
