1. What is Laravel Broadcasting?
Laravel Broadcasting allows you to broadcast your server-side Laravel events to your client-side web application. It makes use of WebSockets to establish a connection between your server and the client, enabling real-time data transmission without the need for polling.
2. Pusher Channels: A Brief Overview
Pusher Channels is a real-time messaging service that allows you to add real-time features to your web and mobile applications. It manages and scales WebSocket connections, ensuring reliable and secure communication between the client and server.
3. Setting Up Laravel with Pusher Channels
To get started, you first need to set up Pusher Channels in your Laravel project.
- Install Pusher PHP Server SDK:
```bash composer require pusher/pusher-php-server ```
- Configure `.env` File:
Add your Pusher credentials to your `.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 `broadcasting.php`:
In `config/broadcasting.php`, set the default broadcaster to Pusher:
```php
'default' => env('BROADCAST_DRIVER', 'pusher'),
```
4. Creating and Broadcasting Events
In Laravel, each broadcast event is represented by a class. Let’s create a simple event.
- Create an Event:
```bash php artisan make:event OrderStatusUpdated ```
- Implement `ShouldBroadcast`:
Update the event class to implement `ShouldBroadcast` and define the data to broadcast:
```php
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
class OrderStatusUpdated implements ShouldBroadcast
{
public $orderId;
public $status;
public function __construct($orderId, $status)
{
$this->orderId = $orderId;
$this->status = $status;
}
public function broadcastOn()
{
return new Channel('orders');
}
}
```
5. Frontend Integration
On the frontend, you need to listen for the event:
- Install Pusher JS Library:
```html <script src="https://js.pusher.com/7.0/pusher.min.js"></script> ```
- Subscribe to the Channel:
```javascript
var pusher = new Pusher('your-app-key', {
cluster: 'your-app-cluster'
});
var channel = pusher.subscribe('orders');
channel.bind('OrderStatusUpdated', function(data) {
alert('Order ' + data.orderId + ' status updated to ' + data.status);
});
```
6. Broadcasting an Event
To broadcast an event, you simply dispatch it from your Laravel application:
```php event(new OrderStatusUpdated($orderId, 'shipped')); ```
