Laravel Websocket Example: A Comprehensive Guide

Introduction

WebSockets are a powerful tool for building real-time applications. They allow for bi-directional communication between the server and the client, enabling you to build applications that can update in real-time without the need for constant polling. Laravel is a popular PHP framework that provides built-in support for WebSockets through the Laravel Echo library.

In this article, we will explore how to use Laravel WebSockets to build real-time applications. We will cover everything from setting up a new Laravel project to creating a simple chat application using WebSockets.

Setting up a new Laravel project

The first step in building a Laravel WebSockets application is to set up a new Laravel project. If you already have a Laravel project, you can skip this step.

1. Open up your terminal or command prompt.
2. Navigate to the directory where you want to create your new Laravel project.
3. Type the following command:

composer create-project –prefer-dist laravel/laravel my-project

This command will create a new Laravel project in the “my-project” directory.

Installing Laravel WebSockets

Once you have created a new Laravel project, the next step is to install Laravel WebSockets.

1. Open up your terminal or command prompt.
2. Navigate to the root directory of your Laravel project.
3. Type the following command:

composer require beyondcode/laravel-websockets

This command will install Laravel WebSockets and all of its dependencies.

Configuring Laravel WebSockets

After installing Laravel WebSockets, you need to configure it to work with your Laravel project.

1. Open up your terminal or command prompt.
2. Navigate to the root directory of your Laravel project.
3. Type the following command:

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

This command will publish the configuration file for Laravel WebSockets to your project’s “config” directory.

Starting the Laravel WebSockets server

Once you have installed and configured Laravel WebSockets, the next step is to start the server.

1. Open up your terminal or command prompt.
2. Navigate to the root directory of your Laravel project.
3. Type the following command:

php artisan websockets:serve

This command will start the Laravel WebSockets server on port 6001.

Creating a simple chat application

Now that you have set up and configured Laravel WebSockets, it’s time to create a simple chat application using WebSockets.

Step 1: Create the chat view

The first step in creating a chat application is to create the chat view. The chat view is the interface that users will use to send and receive messages.

To create the chat view, you can use Laravel’s built-in Blade templating engine. Here is an example of a simple chat view:

“`html

“`

This chat view uses Vue.js to handle the user interface. It displays a list of messages and provides an input field for users to enter new messages.

Step 2: Create the chat controller

The next step in creating a chat application is to create the chat controller. The chat controller is responsible for handling incoming messages and broadcasting them to other users.

To create the chat controller, you can use Laravel’s built-in Artisan command to generate a new controller. Here is an example of a simple chat controller:

“`php

namespace App\Http\Controllers;

use Illuminate\Http\Request;use BeyondCode\LaravelWebSockets\Facades\WebSocketsRouter;

class ChatController extends Controller{public function index(){return view(‘chat’);}

public function sendMessage(Request $request){$message = $request->input(‘message’);

WebSocketsRouter::broadcastToAll([‘message’ => $message]);

return response()->json([‘success’ => true]);}}“`

This chat controller handles two actions: the “index” action, which displays the chat view, and the “sendMessage” action, which broadcasts a message to all connected users.

Step 3: Create the chat routes

The final step in creating a chat application is to create the chat routes. The chat routes map incoming requests to the appropriate controller action.

To create the chat routes, you can use Laravel’s built-in Route facade. Here is an example of the chat routes:

“`php

use Illuminate\Support\Facades\Route;

Route::get(‘/’, ‘ChatController@index’);Route::post(‘/send-message’, ‘ChatController@sendMessage’);“`

These routes map incoming GET requests to the “index” action and incoming POST requests to the “sendMessage” action.
