WebSocket is a communication protocol that enables real-time bidirectional communication between the client and the server. It is a protocol that allows the server to push updates to the client without the client requesting them.

Laravel is a popular PHP web application framework that provides a comprehensive set of tools for building robust web applications. Laravel comes with built-in support for real-time communication using WebSockets.

In this blog, we will discuss the use case of WebSockets in Laravel and how to implement it.

Use Case: WebSockets are particularly useful in real-time applications such as chat applications, online gaming, and collaborative tools. WebSockets can also be used to implement live updates and notifications in applications. For example, imagine a social media platform where users can follow each other’s activities. With WebSockets, the platform can notify a user in real-time when someone they follow posts a new update, comments on their post, or sends them a message.

Implementation: Laravel provides an excellent package for WebSockets called “laravel-websockets.” It is a third-party package that provides a complete solution for implementing WebSockets in Laravel.

To implement WebSockets in Laravel, follow these steps:

Step 1: Install the Laravel WebSockets package

composer require beyondcode/laravel-websockets

Step 2: Publish the package configuration file

php artisan vendor:publish --provider="BeyondCode\LaravelWebSockets\WebSocketsServiceProvider" --tag="config"

Step 3: Configure the WebSockets package

You can configure the package by editing the config/websockets.php file.

Step 4: Start the WebSockets server

You can start the WebSockets server by running the following command:

php artisan websockets:serve

Step 5: Implement WebSockets in your Laravel application

To implement WebSockets in your Laravel application, you need to use a JavaScript library called “laravel-echo.” This library provides an easy-to-use interface for communicating with the Laravel WebSockets server.

Here is an example of how to use Laravel Echo to listen to an event:

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,
    wsHost: window.location.hostname,
    wsPort: 6001,
    forceTLS: false,
});

window.Echo.channel('channel-name')
    .listen('EventName', (data) => {
        console.log(data);
    });

Conclusion: WebSockets provide a powerful and efficient way to implement real-time communication in web applications. Laravel makes it easy to implement WebSockets using the laravel-websockets package. By using WebSockets, you can create real-time applications that provide an immersive and engaging user experience.
