Building a Chat Application with Laravel and WebSockets

In today’s fast-paced digital world, real-time communication is essential for providing a seamless user experience. Whether it’s connecting friends on social media or facilitating business collaboration, chat applications have become an integral part of our lives. In this tutorial, we’ll walk you through the process of building a real-time chat application using Laravel and WebSockets. With Laravel’s powerful features and the efficiency of WebSockets, you can create a robust and responsive chat platform that will delight your users.

Building a Chat Application with Laravel and WebSockets

1. Prerequisites

Before we dive into the technical details, let’s make sure you have everything you need to get started:

  • Basic understanding of Laravel framework
  • Composer installed on your system
  • Laravel project set up on your local machine
  • Basic knowledge of JavaScript and Vue.js (optional, but helpful)

2. Setting Up Laravel Project

If you already have a Laravel project set up, you can skip this step. If not, follow these steps to create a new Laravel project:

1. Open your terminal and navigate to the directory where you want to create the project.

2. Run the following command to create a new Laravel project:

bash
composer create-project --prefer-dist laravel/laravel ChatApp

3. Navigate to the newly created project directory:

bash
cd ChatApp

3. Installing Laravel WebSockets Package

Laravel WebSockets is a package that enables real-time communication between clients and servers using WebSockets. It simplifies the process of creating interactive, real-time applications like chat systems. To install the package, follow these steps:

1. Install the package using Composer:

bash
composer require beyondcode/laravel-websockets

2. Publish the package’s configuration files:

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

3. Migrate the necessary database tables:

bash
php artisan migrate

4. Configuring Laravel WebSockets

To configure Laravel WebSockets for your chat application, follow these steps:

1. Open the config/websockets.php file and make any necessary changes according to your application’s requirements. You can configure settings such as the apps, max_request_size, and path

2. In the config/broadcasting.php file, set the default broadcasting driver to pusher:

php
'default' => env('BROADCAST_DRIVER', 'pusher'),

3. Set your Pusher credentials in the .env file:

env
BROADCAST_DRIVER=pusher
PUSHER_APP_ID=your-app-id
PUSHER_APP_KEY=your-app-key
PUSHER_APP_SECRET=your-app-secret
PUSHER_APP_CLUSTER=mt1

5. Creating the Chat Interface

Now that we have Laravel WebSockets set up, let’s create the chat interface using Laravel’s powerful Blade templating engine and Vue.js (optional). We’ll create a simple chat room where users can send and receive messages in real-time.

  1. Create a new Blade view file named chat.blade.php in the resources/views directory.
  2. Build the basic structure of the chat interface using HTML and CSS. You can style it according to your application’s design.
  3. Integrate Vue.js to handle real-time updates and user interactions. If you’re new to Vue.js, you can include it via a CDN or set up a build process using Laravel Mix.

6. Implementing Real-Time Chat Functionality

With the chat interface in place, let’s implement the real-time chat functionality using Laravel WebSockets.

1. In your chat.blade.php file, include the necessary JavaScript libraries and create a Vue instance to manage the chat application’s behavior.

html
<script src="https://cdn.jsdelivr.net/npm/vue@2.6.14/dist/vue.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/laravel-echo/1.11.4/echo.js"></script>
<script src="{{ asset('js/app.js') }}"></script> <!-- Your custom JavaScript file -->

2. Initialize Echo in your JavaScript file (app.js in this case):

javascript
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,
});

3. Set up listeners to receive and display messages in real-time:

javascript
new Vue({
    el: '#app',
    data: {
        messages: [],
        newMessage: '',
    },
    mounted() {
        window.Echo.private('chat')
            .listen('MessageSent', (e) => {
                this.messages.push({
                    message: e.message.message,
                    user: e.user,
                });
            });
    },
    methods: {
        sendMessage() {
            if (this.newMessage.trim() === '') return;
            
            axios.post('/send', {
                message: this.newMessage,
            });
            
            this.newMessage = '';
        },
    },
});

4. Create a route and controller to handle message sending:

php
Route::post('/send', 'ChatController@sendMessage');

In your ChatController:

php
public function sendMessage(Request $request)
{
    $user = auth()->user();
    
    event(new MessageSent($user, $request->message));
}
