How to use Laravel Echo for broadcasting events with vue js



Image not found!!

Laravel Echo is a tool that makes it easy to work with WebSockets and broadcasting events in a Laravel application. When combined with Vue.js, you can create real-time, reactive applications. Here's a step-by-step guide on how to use Laravel Echo for broadcasting events with Vue.js:

  1. Install Laravel Echo and Pusher:

    Make sure you have Laravel Echo and a broadcasting service like Pusher installed. You can install these using Composer:

    bash
    composer require pusher/pusher-php-server

    Also, configure your .env file with your Pusher credentials:

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

  2. Install Laravel Echo and Vue.js:

    Install Laravel Echo and Vue.js packages using npm:

    bash
    npm install --save laravel-echo pusher-js

  3. Configure Laravel Echo:

    In your resources/js/bootstrap.js file, import and configure Laravel Echo. Replace the Pusher settings with your own:

    javascript
    import Echo from 'laravel-echo';

window.Echo = new Echo({
    broadcaster: 'pusher',
    key: process.env.MIX_PUSHER_APP_KEY,
    cluster: process.env.MIX_PUSHER_APP_CLUSTER,
    encrypted: true,
});

  4. Broadcast an Event in Laravel:

    Create an event in Laravel that you want to broadcast. For example, let's say you have an event called SomeEvent. Make sure it implements ShouldBroadcast:

    php
    namespace App\Events;

use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Queue\SerializesModels;

class SomeEvent implements ShouldBroadcast
{
    use SerializesModels;

    public $data;

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

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

  5. Broadcast the Event:

    In your controller or wherever you want to broadcast the event, use the event function:

    php
    event(new SomeEvent($data));

  6. Listen for the Event in Vue Component:

    In your Vue component, use Laravel Echo to listen for the event:

    javascript
    mounted() {
    window.Echo.channel('some-channel')
        .listen('SomeEvent', (event) => {
            console.log('Received SomeEvent', event);
            // Handle the event data as needed
        });
}

    Make sure you call this within a lifecycle hook like mounted().

  7. Compile Assets:

    After making changes to your JavaScript files, compile your assets:

    bash
    npm run dev

  8. Run Laravel WebSocket Server:

    Start the Laravel WebSocket server to handle the broadcasting:

    bash
    php artisan websockets:serve

    Note: The websockets package is required for this, and you can install it using:

    bash
    composer require beyondcode/laravel-websockets

  9. Run Laravel Application:

    Run your Laravel application:

    bash
    php artisan serve

    Now, when the event is broadcasted, your Vue component should receive it in real-time.

Make sure you have a working WebSocket server for Laravel. The laravel-websockets package is used in this example, but you can choose other packages as well. Adjust the configurations accordingly based on the package you use.
