Laravel 11 Reverb Real-Time Notifications

What is Reverb?

Laravel Reverb brings blazing-fast and scalable real-time WebSocket communication directly to your Laravel application, and provides seamless integration with Laravel existing suite of event broadcasting tools. Laravel Reverb Documantation

Here is what we will do in this Laravel 11 Reverb Real-Time Notifications example:

1. Create authentication (auth) scaffolding using Laravel UI.

2. Set up two types of users: a super admin and a normal user. We will identify them using an “is_admin” column in the users table.

3. Create a posts table with columns for the title and body.

4. Allow users to create posts with title and body.

5. Once a post is created, the admin will get a realtime notification using Reverb. we will create PostCreate Event for send realtime notification.

Step for Laravel 11 Reverb Real-Time Notifications Example

• Step 1: Install Laravel 11
• Step 2: Create Auth using Scaffold
• Step 3: Create Migrations
• Step 4: Create and Update Models
• Step 5: Setup Reverb & Echo Server
• Step 6: Create PostCreate Event
• Step 7: Create Routes
• Step 8: Create Controller
• Step 9: Create and Update Blade Files
• Step 10: Create Admin User
• Run Laravel App

Step 1: Install Laravel 11

This step is not required; however, if you have not created the Laravel app, then you may go ahead and execute the below command:

composer create-project laravel/laravel example-app

Step 2: Create Auth using Scaffold

Now, in this step, we will create an auth scaffold command to generate login, register, and dashboard functionalities. So, run the following commands:

Laravel 11 UI Package:

composer require laravel/ui 

Generate Auth:

php artisan ui bootstrap --auth 

npm install

npm run build

Step 3: Create Migrations

Here, we will create posts and add is_admin column to users table. so, let’s run the following command:

php artisan make:migration add_is_admin_column_table

php artisan make:migration create_posts_table

now, let’s update the following migrations:

database/migrations/2024_06_18_140624_add_is_admin_column.php

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    /**
     * Run the migrations.
     */
    public function up(): void
    {
        Schema::table('users', function (Blueprint $table) {
            $table->tinyInteger('is_admin')->default(0);
        });
    }

    /**
     * Reverse the migrations.
     */
    public function down(): void
    {
        //
    }
};

database/migrations/2024_06_18_140906_create_posts_table.php

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    /**
     * Run the migrations.
     */
    public function up(): void
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->foreignId('user_id')->constrained()->onDelete('cascade');
            $table->string('title');
            $table->text('body');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     */
    public function down(): void
    {
        Schema::dropIfExists('posts');
    }
};

now, Let’s run the migration command:

php artisan migrate

Step 4: Create and Update Models

Here, we will create Post model using the following command. we also need to update User model here. we will write relationship and some model function for like and dislike.

php artisan make:model Post

now, update the model file with hasMany() relationship:

app/Models/Post.php

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    use HasFactory;

    protected $fillable = ['title', 'body', 'user_id'];

    /**
     * Write code on Method
     *
     * @return response()
     */
    public function user()
    {
        return $this->belongsTo(User::class);
    }
}

app/Models/User.php

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;

class User extends Authenticatable
{
    use HasFactory, Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name',
        'email',
        'password',
        'is_admin'
    ];

    /**
     * The attributes that should be hidden for serialization.
     *
     * @var array
     */
    protected $hidden = [
        'password',
        'remember_token',
    ];

    /**
     * Get the attributes that should be cast.
     *
     * @return array
     */
    protected function casts(): array
    {
        return [
            'email_verified_at' => 'datetime',
            'password' => 'hashed',
        ];
    }
}

Step 5: Setup Reverb & Echo Server

Now, we need to configure laravel broadcast and Reverb as driver.

So, first by default laravel has not enabled broadcasting, so you need to run the following command to enable it.

php artisan install:broadcasting

laravel will ask to install Reverb and you need to select “Yes”. then it will automatically installed it. You Can Learn How to Add Watermark on Image Laravel 11

You need to run the following commands to install Reverb. it’s option if you already selected yes then.

composer require laravel/reverb

php artisan reverb:install

Now, we will install laravel echo server, so, let’s run the below commands:

npm install --save-dev laravel-echo

now, you will see some code on the echo.js file, where you can made a changes:

resources/js/echo.js

import Echo from 'laravel-echo';

import Pusher from 'pusher-js';
window.Pusher = Pusher;

window.Echo = new Echo({
    broadcaster: 'reverb',
    key: import.meta.env.VITE_REVERB_APP_KEY,
    wsHost: import.meta.env.VITE_REVERB_HOST,
    wsPort: import.meta.env.VITE_REVERB_PORT ?? 80,
    wssPort: import.meta.env.VITE_REVERB_PORT ?? 443,
    forceTLS: (import.meta.env.VITE_REVERB_SCHEME ?? 'https') === 'https',
    enabledTransports: ['ws', 'wss'],
});

Then, set the BROADCAST_CONNECTION environment variable to Reverb in your application’s .env file, also we will add Reverb env variables:

.env

BROADCAST_CONNECTION=reverb

REVERB_APP_ID=256980
REVERB_APP_KEY=f4l2tmwqf6eg0f6jz0mw
REVERB_APP_SECRET=zioqeto9xrytlnlg7sj6
REVERB_HOST="localhost"
REVERB_PORT=8080
REVERB_SCHEME=http

VITE_REVERB_APP_KEY="${REVERB_APP_KEY}"
VITE_REVERB_HOST="${REVERB_HOST}"
VITE_REVERB_PORT="${REVERB_PORT}"
VITE_REVERB_SCHEME="${REVERB_SCHEME}"

Now again build your JS:

npm run build

Step 6: Create PostCreate Event

In this step, we need to create “Event” by using the Laravel artisan command, so let’s run the command below. We will create the PostCreate event class.

next, run the following command to create event class.

php artisan make:event PostCreate

Now you can see a new folder created as “Events” in the app folder. You need to make the following changes as shown in the class below.

app/Events/PostCreate.php

<?php

namespace App\Events;

use Illuminate\Broadcasting\Channel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Broadcasting\ShouldBroadcastNow;

class PostCreate implements ShouldBroadcastNow
{
    use Dispatchable, InteractsWithSockets, SerializesModels;

     public $post;

    /**
     * Create a new event instance.
     */
    public function __construct($post)
    {
        $this->post = $post;
    }

    /**
     * Write code on Method
     *
     * @return response()
     */
    public function broadcastOn()
    {
        return new Channel('posts');
    }

    /**
     * Write code on Method
     *
     * @return response()
     */
    public function broadcastAs()
    {
        return 'create';
    }

    /**
     * Get the data to broadcast.
     *
     * @return array
     */
    public function broadcastWith(): array
    {
        return [
            'message' => "[{$this->post->created_at}] New Post Received with title '{$this->post->title}'."
        ];
    }
}

Step 7: Create Routes

In this step, we need to create some routes for realtime notification. So open your “routes/web.php” file and add the following route.

routes/web.php

<?php

use Illuminate\Support\Facades\Route;

use App\Http\Controllers\PostController;

Route::get('/', function () {
    return view('welcome');
});

Auth::routes();

Route::get('/home', [App\Http\Controllers\HomeController::class, 'index'])->name('home');

Route::get('/posts', [PostController::class, 'index'])->name('posts.index');
Route::post('/posts', [PostController::class, 'store'])->name('posts.store');

Step 8: Create Controller

Here, we require the creation of a new controller, PostController, with an index method to send a notification route. So let’s put the code below.

app/Http/Controllers/PostController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Post;
use App\Events\PostCreate;

class PostController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index(Request $request)
    {
        $posts = Post::get();

        return view('posts', compact('posts'));
    }

    /**
     * Write code on Method
     *
     * @return response()
     */
    public function store(Request $request)
    {
        $this->validate($request, [
             'title' => 'required',
             'body' => 'required'
        ]);
   
        $post = Post::create([
            'user_id' => auth()->id(),
            'title' => $request->title,
            'body' => $request->body
        ]);

        event(new PostCreate($post));
   
        return back()->with('success','Post created successfully.');
    }
}

Step 9: Create and Update Blade Files

In this step, we will update app.blade.php file and create posts.blade file. so, let’s update it.

resources/views/layouts/app.blade.php

<!doctype html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">

                    <ul class="navbar-nav me-auto">

{
    /**
     * Run the database seeds.
     */
    public function run(): void
    {
        User::create([
            'name' => 'Admin',
            'email' => 'admin@gmail.com',
            'password' => bcrypt('123456'),
