In this example we will see laravel firebase push notification, firebase notification through you can notify user that new email or other messages are available to sync.

    firebase push notification is a free open source and you can easily implement using your google account., firebase messaging or Firebase Cloud Messaging (FCM) is a cross-platform messaging solution that lets you reliably send messages at no cost., FCM push notification used for android,ios as well as web application.

    Here i will give example of firebase web push notification or firebase web push notification in laravel, Firebase provides a realtime database and backend as a service. The service provides application developers an API that allows application data to be synchronized across clients and stored on Firebase’s cloud.

    Here we will see how to set firebase push notification in laravel step by step.

Step 1 : Create Firebase Project and App for Firebase Push Notification

    First of all we will login into Firebase Console  and create new project for laravel firebase push notification.

Step 2 : Install Laravel 8 

    Now install new application for this example using below command

composer create-project --prefer-dist laravel/laravel Firebase_Example

Step 3 : Create Laravel 8 Auth Using Command

    Now create login system using auth command in laravel 8, raun below command in your terminal.

composer require laravel/ui

php artisan ui bootstrap --auth  // For Generate Auth

npm install // TO Install NPM 

npm run dev

Step 4 : Create Migration and Model

    In this forth step we will add new row "device_token" in users table as well as model and after that we will to create new migration. 

php artisan make:migration add_column_device_token

<?php

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

class AddColumnDeviceTokenToUsersTable extends Migration
{
  
    public function up()
    {
        Schema::table('users', function (Blueprint $table) {
            $table->string('device_token')->nullable();
        });
    }

    public function down()
    {
        Schema::table('users', function (Blueprint $table) {
            //
        });
    }
}

    app/Models/User.php

<?php

namespace App\Models;

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

class User extends Authenticatable
{
    use HasFactory, Notifiable;

  
    protected $fillable = [
        'name',
        'email',
        'password',
        'device_token'
    ];

  
    protected $hidden = [
        'password',
        'remember_token',
    ];

    protected $casts = [
        'email_verified_at' => 'datetime',
    ];
}

    Now, run below command to run migration

php artisan migrate

Step 5 : Create Route

    Now w will add new routes to store token and send push notification in laravel so, copy below code in your routes/web.php file

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\HomeController;


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

Auth::routes();   
Route::get('/home', [HomeController::class, 'index'])->name('home');
Route::post('/save-push-notification-token', [HomeController::class, 'savePushNotificationToken'])->name('save-push-notification-token');
Route::post('/send-push-notification', [HomeController::class, 'sendPushNotification'])->name('send.push-notification');

Step 6 : Create Controller

    Here, I have created HomeController and added savePushNotificationToken() and  sendPushNotification() function. in this controller you need to add server API key , you need to add your server key. 

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\User;

class HomeController extends Controller
{

    public function __construct()
    {
        $this->middleware('auth');
    }

    public function index()
    {
        return view('home');
    }

    public function savePushNotificationToken(Request $request)
    {
        auth()->user()->update(['device_token'=>$request->token]);
        return response()->json(['token saved successfully.']);
    }
    
    public function sendPushNotification(Request $request)
    {
        $firebaseToken = User::whereNotNull('device_token')->pluck('device_token')->all();
          
        $SERVER_API_KEY = 'Enter_Your_Server_Key';
  
        $data = [
            "registration_ids" => $firebaseToken,
            "notification" => [
                "title" => $request->title,
                "body" => $request->body,  
            ]
        ];
        $dataString = json_encode($data);
    
        $headers = [
            'Authorization: key=' . $SERVER_API_KEY,
            'Content-Type: application/json',
        ];
    
        $ch = curl_init();
      
        curl_setopt($ch, CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send');
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $dataString);
               
        $response = curl_exec($ch);
  
        dd($response);
    }
}

Step 7 : Update Blade File

    Now, you need to update on your home.blade.php file and add below code.

@extends('layouts.app')

@section('content')
<div class="container">
    <div class="row justify-content-center">
        <center><h2>Laravel Firebase Push Notification - websolutionstuff.com</h2></center>
        <div class="col-md-8">            
             <center>
                <button id="btn-nft-enable" onclick="initFirebaseMessagingRegistration()" class="btn btn-danger btn-xs btn-flat">Allow for Notification</button>
            </center><br>
            <div class="card">
                <div class="card-header">{{ __('Dashboard') }}</div>

                <div class="card-body">
                    @if (session('status'))
                        <div class="alert alert-success" role="alert">
                            {{ session('status') }}
                        </div>
                    @endif
                    <form action="{{ route('send.push-notification') }}" method="POST">

                        @csrf

                        <div class="form-group">

                            <label>Title</label>

                            <input type="text" class="form-control" name="title">

                        </div>

                        <div class="form-group">

                            <label>Body</label>

                            <textarea class="form-control" name="body"></textarea>

                          </div>

                        <button type="submit" class="btn btn-primary">Send Notification</button>

                    </form>
                </div>
            </div>
        </div>
    </div>
</div>

    apiKey: "XXXX",
    authDomain: "XXXX.firebaseapp.com",
    projectId: "XXXX",
    storageBucket: "XXXX.appspot.com",
    messagingSenderId: "XXXX",
    databaseURL: "https://Your_Project_ID.firebaseio.com",
    appId: "XXXX"
  };
      
    firebase.initializeApp(firebaseConfig);
    const messaging = firebase.messaging();
  
    function initFirebaseMessagingRegistration() {
            messaging
            .requestPermission()
            .then(function () {
                return messaging.getToken({ vapidKey: 'Your_Public_Key' })
            })
            .then(function(token) {
                console.log(token);
   
                $.ajaxSetup({
                    headers: {
                        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
                    }
                });
  
                $.ajax({
                    url: '{{ route("save-push-notification-token") }}',
                    type: 'POST',
                    data: {
                        token: token

                    dataType: 'JSON',
                    success: function (response) {
                        alert('Token saved successfully.');
                    },
                    error: function (err) {
                        console.log('User Chat Token Error'+ err);
                    },
                });
  
            }).catch(function (err) {
                console.log('User Chat Token Error'+ err);
            });
     }  
      
    messaging.onMessage(function(payload) {
        const noteTitle = payload.notification.title;
        const noteOptions = {
            body: payload.notification.body,
            icon: payload.notification.icon,
        };
        new Notification(noteTitle, noteOptions);
    });
   
</script>
@endsection

Step 8 : Create firebase-messaging-sw.js File

    Now, we will create firebase-messaging-sw.js in public folder and copy below code.

importScripts('https://www.gstatic.com/firebasejs/8.3.0/firebase-app.js');
importScripts('https://www.gstatic.com/firebasejs/8.3.0/firebase-messaging.js');
   
	firebase.initializeApp({
        apiKey: "XXXX",
	    authDomain: "XXXX.firebaseapp.com",
	    databaseURL: "https://Your_Project_Id.firebaseio.com",
	    projectId: "XXXX",
	    storageBucket: "XXXX.appspot.com",
	    messagingSenderId: "XXXX",	    
	    appId: "XXXX"
    });

	const messaging = firebase.messaging();
	messaging.setBackgroundMessageHandler(function(payload) {
    console.log(
        "[firebase-messaging-sw.js] Received background message ",
        payload,
    );
        
    const notificationTitle = "Background Message Title";
    const notificationOptions = {
        body: "Background Message body.",
        icon: "/itwonders-web-logo.png",
    };
  
    return self.registration.showNotification(
        notificationTitle,
        notificationOptions,
    );
});

    Output :
