Laravel 11 Reverb Real-Time Notifications

Hello, laravel web developers! In this article, we'll see how to send real-time notifications in laravel 11 using Reverb. In laravel 11 reverb, we'll send real-time notifications. Reverb is fine-tuned for speed. A single server can support thousands of connections, piping data without the delay and inefficiency of HTTP polling.

Reverb is a first-party WebSocket server for Laravel applications, bringing real-time communication between client and server directly to your fingertips. Open source and an Artisan command away - with love from the Laravel team.

Laravel 11 Reverb Real-Time Notifications

In this step, we'll install the laravel 11 application using the following command.

composer create-project laravel/laravel laravel-11-example

Next, we'll create a laravel auth using the following command.

composer require laravel/ui

php artisan ui bootstrap --auth

npm install

npm run build

Then, we'll create a migration using the following command.

php artisan make:migration add_is_admin_column_table

php artisan make:migration create_posts_table

Migration:

<?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
    {
        //
    }
};

Post migration:

<?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');
    }
};

Next, we'll migrate the table into the database using the following command.

php artisan migrate

Now, we'll create a model using the following command.

php artisan make:model Post

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',
        ];
    }
}

Now, we'll configure laravel broadcast and Reverb as driver.

By default, laravel has not enabled broadcasting. So, run the following command to enable broadcasting.

php artisan install:broadcasting

Laravel will ask to install Reverb and you need to select Yes. Then it will automatically install it.

Run the following commands to install Reverb.

composer require laravel/reverb

php artisan reverb:install

Next, we'll install the laravel echo server.

npm install --save-dev laravel-echo

 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

.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, run the following command to build the JS.

npm run build

Then, we'll create an Event using the following command.

php artisan make:event PostCreate

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}'."
        ];
    }
}

Now, define the routes into the web.php.

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');

Now, we'll create a controller and add the following function to controller file.

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.');
    }
}

Next, we'll update the blade.

@endsection

@section('script')
@if(auth()->user()->is_admin)
    <script type="module">
            window.Echo.channel('posts')
                .listen('.create', (data) => {
                    console.log('Order status updated: ', data);
                    var d1 = document.getElementById('notification');
                    d1.insertAdjacentHTML('beforeend', '<div class="alert alert-success alert-dismissible fade show"><span><i class="fa fa-circle-check"></i>  '+data.message+'</span></div>');
                });
    </script>
@endif
@endsection

Then, we'll create a seeder using the following command.

php artisan make:seeder CreateAdminUser

database/seeders/CreateAdminUser.php

<?php

namespace Database\Seeders;

use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;
use App\Models\User;

class CreateAdminUser extends Seeder
{
    /**
     * Run the database seeds.
     */
    public function run(): void
    {
        User::create([
            'name' => 'Admin',
            'email' => '[email protected]',
            'password' => bcrypt('123456'),
            'is_admin' => 1
        ]);
    }
}

Now, run the laravel 11 application using the following command.

php artisan serve

php artisan reverb:start
