Laravel Websockets is a package that provides easy-to-use WebSocket servers for Laravel applications. It allows real-time communication between the server and the client. In this tutorial, we will learn how to handle incoming messages using the OnMessage event in Laravel Websockets.
Here is an example of how to listen for the OnMessage event:
use BeyondCode\LaravelWebSockets\WebSockets\Channels\ChannelManager;
use BeyondCode\LaravelWebSockets\WebSockets\WebSocket;
public function handle(WebSocket $webSocket, ChannelManager $channelManager, Message $message)
{
// Handle incoming message here
}
The $webSocket variable gives us access to the WebSocket instance. The $channelManager variable is used for managing channels. The $message variable holds the incoming message.
Here is an example of how to use the OnMessage event to broadcast to a channel:
use BeyondCode\LaravelWebSockets\WebSockets\Channels\ChannelManager;
use BeyondCode\LaravelWebSockets\WebSockets\WebSocket;
public function handle(WebSocket $webSocket, ChannelManager $channelManager, Message $message)
{
$channel = $channelManager->find('my-channel');
$channel->broadcast([
'message' => $message->getContent(),
]);
}
Here, we first find the channel we want to broadcast to using the ChannelManager. We then use the broadcast method on the channel, passing in an array with the message content.
Laravel Websockets provides a lot of flexibility for handling incoming messages, and the OnMessage event is just one of the ways to handle them. By using this powerful package, you can build real-time communication features into your Laravel applications with ease.
