In this article, we will see a laravel 9 firebase push notification, a firebase notification through you can notify users that new emails or other messages are available to sync. In this example, we will learn how to send web push notifications in laravel 9 using firebase.

    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 notifications are used for android, ios as well as a web applications.

    Here I will give an example of a "firebase web push notification" or firebase web push notification in laravel 9, Firebase provides a real-time 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 9 step by step.

    In this step, we will log in to Firebase Console and create a new project for laravel firebase push notification.

    Now, install new laravel 9 application using the below command

composer create-project --prefer-dist laravel/laravel Laravel_9_Firebase_Example

    Now, create a login system using auth command in laravel 9, and run the following command in your terminal.

composer require laravel/ui

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

npm install // TO Install NPM 

npm run dev

    In this step, we will add a new row "device_token" in the user's table as well as the model.

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 the below command to run the migration.

php artisan migrate

    Now, we will add routes to store tokens and send push notifications in laravel. So, copy the 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');

    Here, I have created HomeController and added savePushNotificationToken() and  sendPushNotification() function. In this controller, you need to add the server API 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);
    }
}

    Now, we will update the home.blade.php file.

@extends('layouts.app')

@section('content')
<div class="container">
    <div class="row justify-content-center">
        <center><h2>Laravel 9 FCM Push Notification - Websolutionstuff</h2></center>

    appId: "XXXX"
  };
      
    firebase.initializeApp(firebaseConfig);
    const messaging = firebase.messaging();
  
    function initFirebaseMessagingRegistration() {
            messaging
            .requestPermission()
            .then(function () {

        new Notification(noteTitle, noteOptions);
    });
   
</script>
@endsection

    Now, we will create firebase-messaging-sw.js in the public folder. So, add the below code in the js file.

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,
    );
});
