Facilitating frictionless, bi-directional data flow between servers and clients, WebSockets have revolutionized real-time communication within web applications. Being one of the most widely used PHP frameworks, Laravel provides a convenient way to integrate WebSockets, enabling developers to create interactive apps such as live chat, notifications, real-time dashboards, and collaboration tools.
This step-by-step guide walks you through embedding WebSockets in Laravel, covering setup, configuration, broadcasting events, and frontend integration in a simple, categorized manner.
WebSocket is a protocol that provides full-duplex communication between a client and a server through a single, long-lasting connection. Unlike traditional HTTP requests that require repeated polling, WebSockets allow instant and efficient data exchange without unnecessary latency.
Step 1: Install Laravel and the WebSockets Package
Ensure Laravel is installed, then install the WebSockets package using Composer:
composer require beyondcode/laravel-websockets
Step 2: Publish the WebSockets Configuration File
After installation, publish the WebSockets configuration file with:
php artisan vendor:publish --provider="BeyondCode\LaravelWebSockets\WebSocketsServiceProvider" --tag="config"
This creates a `websockets.php` file in the `config` directory, where you can customize WebSocket settings.
Step 3: Configure WebSockets in Laravel
Modify the `.env` file to enable WebSockets and configure Pusher settings:
PUSHER_APP_ID=your-app-id
PUSHER_APP_KEY=your-app-key
PUSHER_APP_SECRET=your-app-secret
PUSHER_APP_CLUSTER=mt1
Update these values with your Pusher credentials or customize as needed for your WebSocket setup.
Step 4: Set Up and Start the WebSocket Server
Run the following command to start the WebSocket server:
php artisan websockets:serve
This command initiates a WebSocket server to handle real-time connections.
Laravel allows event broadcasting using WebSockets. Here’s how to create and broadcast events:
Step 5: Create a WebSocket Event
php artisan make:event MessageSent
Modify the `MessageSent.php` file in the `App\Events` directory:
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Queue\SerializesModels;
class MessageSent implements ShouldBroadcast
{
use InteractsWithSockets, SerializesModels;
public $message;
public function __construct($message)
{
$this->message = $message;
}
public function broadcastOn()
{
return ['chat-channel'];
}
}
This event broadcasts messages to the `chat-channel` using WebSockets.
Step 6: Listen for WebSocket Events on the Frontend
Integrate Laravel Echo on the frontend to receive and display messages in real-time:
window.Echo.channel('chat-channel')
.listen('MessageSent', (e) => {
console.log(e.message);
});
This JavaScript code listens for `MessageSent` events on the `chat-channel` and logs the message to the console.
Step 7: Sending Messages
Trigger the WebSocket event from a controller method:
use App\Events\MessageSent;
public function sendMessage(Request $request)
{
event(new MessageSent($request->message));
return response()->json(['status' => 'success']);
}
This method triggers the `MessageSent` event, broadcasting the message without reloading the page.
WebSockets in Laravel enable dynamic and interactive web applications with real-time features like live chat, notifications, and collaborative tools. By effortlessly broadcasting events and updating content in real-time, this approach boosts user engagement, providing a seamless and responsive experience without the lags associated with traditional polling methods. With the `beyondcode/laravel-websockets` package and Laravel Echo, developers can quickly set up and scale real-time communication in their applications.
