Laravel Websockets Example: Building Real-Time Applications

If you’re looking to build real-time applications with Laravel, using websockets is a great way to achieve this. Websockets allow for real-time communication between a client and server, making it perfect for applications such as chat rooms, real-time games, and more. In this article, we will explore Laravel websockets example and how to implement them in your projects.

What are Websockets?

Websockets are a protocol that enables real-time communication between a client and server. Unlike traditional HTTP requests, which are stateless and require a new request/response cycle for each communication, websockets maintain a persistent connection between the client and server, allowing for bidirectional communication in real-time.

Why Use Websockets?

Websockets are ideal for applications that require real-time communication, such as chat rooms, real-time games, and collaborative applications. They are also more efficient than traditional HTTP requests since they eliminate the need for repeated request/response cycles. Additionally, websockets are supported by all major browsers and can be used with Laravel to build real-time applications quickly and easily.

Setting up Laravel Websockets

The first step to using Laravel websockets is to install the required package. You can do this using composer by running the following command:

composer require beyondcode/laravel-websockets

Once the package is installed, you will need to publish the configuration file using the following command:

php artisan vendor:publish –provider=”BeyondCode\\LaravelWebSockets\\WebSocketsServiceProvider” –tag=”config”

This will create a new configuration file in your project’s config directory called websockets.php. This file contains all the configuration options for Laravel websockets.

Configuring Laravel Websockets

Before you can start using Laravel websockets, you need to configure it. The configuration file contains several options that you can use to customize your websockets setup. Here are some of the most important options:

Dashboard Configuration

The dashboard configuration options allow you to customize the appearance and behavior of the websockets dashboard. You can use these options to change the default dashboard URL, enable or disable SSL, and more.

SSL Configuration

If you’re using SSL with your websockets, you can configure it using the SSL configuration options. You can enable or disable SSL, specify the SSL certificate file path, and more.

Channel Configuration

The channel configuration options allow you to define the channels that your websockets will use. You can specify the channel name, the channel type (public or private), and more.

Authentication Configuration

If you’re using private channels with your websockets, you will need to configure authentication. The authentication configuration options allow you to specify the authentication guard that your websockets will use, the authentication provider, and more.

Creating a Laravel Websockets Example Application

Now that you have Laravel websockets set up and configured, you can start building your real-time application. In this example, we will create a simple chat application that demonstrates how to use websockets in Laravel.

Step 1: Install Laravel

If you haven’t already, you will need to install Laravel. You can do this using composer by running the following command:

composer create-project –prefer-dist laravel/laravel laravel-websockets-example

Step 2: Install Laravel Websockets

Next, you will need to install Laravel websockets. You can do this using composer by running the following command:

composer require beyondcode/laravel-websockets

Step 3: Create a Chat Controller

Next, you will need to create a controller for your chat application. You can do this using the following command:

php artisan make:controller ChatController

Once the controller is created, open it in your editor and add the following methods:

A method to return the chat view:

public function index()

{

return view(‘chat’);

}
A method to handle incoming chat messages:

public function sendMessage(Request $request)

{

$message = $request->input(‘message’);

event(new ChatMessage($message));

}

The first method simply returns the chat view. The second method handles incoming chat messages by broadcasting the message using Laravel websockets.

Step 4: Create a Chat View

Next, you will need to create a view for your chat application. You can do this by creating a new file called chat.blade.php in your project’s resources/views directory. Here’s an example of what this file might look like:

<!DOCTYPE html>

<head>

</head>

<body>

</div>

</div>

window.Echo.channel(‘chat’)

.listen(‘ChatMessage’, (e) => {

console.log(e.message);

});

</script>

</body>

This view includes a form for sending messages and a script that listens for incoming chat messages using Laravel websockets.

Step 5: Create a Chat Event

Next, you will need to create an event that will be broadcasted when a new chat message is sent. You can do this using the following command:

php artisan make:event ChatMessage

Once the event is created, open it in your editor and add the following:

public $message;

This property will hold the message that was sent. Next, add the following constructor:

public function __construct($message)

{

$this->message = $message;

}

This constructor sets the message property to the message that was sent. Finally, add the following broadcastOn method:

public function broadcastOn()

{

return new Channel(‘chat’);

}

This method specifies the channel that the event should be broadcasted on.

Step 6: Start Laravel Websockets Server

Finally, you need to start the Laravel websockets server. You can do this using the following command:

php artisan websockets:serve

This will start the Laravel websockets server on port 6001. You can now visit your chat application in your browser and start chatting in real-time!
