Buat Model dan Migration

untuk Menyimpan Token kita perlu membuat migrasi dan model. bisa dengan command seperti berikut

php artisan make:model FirebaseAuthToken -m

Setelah dibuat. buka file nya dan sesuaikan seperti berikut

 public function up(): void
    {
        Schema::create('firebase_auth_tokens', function (Blueprint $table) {
            $table->id();
            $table->foreignId('user_id')->constrained('users')->cascadeOnUpdate()->cascadeOnDelete();
            $table->string('token');
            $table->timestamps();
        });
    }

Setup

Buka File config/services.php dan tambahkan kode berikut.

'firebase' => [
   'project_id' => env('FIREBASE_PROJECT_ID'),
   'file_json'  => env('FIREBASE_CONFIG_FILE')
],

Jangan lupa tambah juga di ENV Varibale nya

FIREBASE_PROJECT_ID=blablablaaaa....
FIREBASE_CONFIG_FILE=blablablaaaa....

Contoh Service

buat file baru dengan nama FirebaseMessagingService.php di App\Services

<?php

namespace App\Services;

use Google_Client;
use Illuminate\Support\Facades\Storage;

class FirebaseMessagingService
{

    public function sendNotification($title, $body, $token, $payload = null)
    {

        $jsonConfig = config('services.firebase.file_json');

        $projectId = config('services.firebase.project_id');
        $credentialsFilePath = storage_path('app/json/'.$jsonConfig);

        $client = new Google_Client();
        $client->setAuthConfig($credentialsFilePath);
        $client->addScope('https://www.googleapis.com/auth/firebase.messaging');
        $client->refreshTokenWithAssertion();
        $client = $client->getAccessToken();

        $access_token = $client['access_token'];

        $headers = [
            "Authorization: Bearer $access_token",
            'Content-Type: application/json'
        ];

        $data = [
            "message" => [
                "token" => $token,
                "notification" => [
                    "title" => $title,
                    "body" => $body,
                ],
                "data"  => $payload
            ]
        ];
        $payload = json_encode($data);

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, "https://fcm.googleapis.com/v1/projects/{$projectId}/messages:send");
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);
        curl_setopt($ch, CURLOPT_VERBOSE, true); // Enable verbose output for debugging
        $response = curl_exec($ch);
        $err = curl_error($ch);
        curl_close($ch);

        if ($err) {
            \Log::error('FCM Notification Error: ' . $err);
        } else {
            $responseData = json_decode($response);
            \Log::info('FCM Notification Sent: ' . json_encode($responseData));

        }
    }
}

Contoh Penerapan

1. Import

use App\Services\FirebaseMessagingService;

2. Gunakan

 public function sendNotification(FirebaseMessagingService $firebaseMessagingService)
    {
        $users = User::whereHas('firebaseTokens')->get();
        foreach ($users as $user) {
            $firebase = FirebaseAuthToken::where('user_id', $user->id)
                ->orderBy('id', 'desc')
                ->first();

            if ($firebase) {
                $firebaseMessagingService->sendNotification($this->notif_title, $this->notif_body, $firebase->token);
            }
        }
    }

contoh diatas untuk mengirim ke seluruh pengguna yang memiliki token
