Hello @nazreen-cod

Can you show what you have tried? That can help people to answer your question :)

hi @tvbeek

I'm trying to connect a Laravel web application to Firebase, but I've run into difficulties. Specifically, I followed a tutorial and installed the necessary package (kreait/laravel-firebase), but I’m unable to establish a connection.

Steps I’ve Taken: 1.Created a new Laravel project:laravel new fyp_firebase

2.Installed the kreait/laravel-firebase package:composer require kreait/laravel-firebase

3.Downloaded the Firebase Service Account JSON key from the Firebase Console (Settings → Service Accounts → Generate New Private Key).

4.Configured the .env file to add Firebase credentials:FIREBASE_CREDENTIALS=/path/to/firebase-service-account.json

5.Published the Firebase configuration to configure the package: php artisan vendor:publish --provider="Kreait\Laravel\Firebase\ServiceProvider"

6.Configured config/firebase.php: The Firebase config file was automatically generated, and I updated it to include the correct path to the Firebase service account key:

return [
    'credentials' => env('FIREBASE_CREDENTIALS'),
    // other settings like database URL
];

@nazreen-cod can you show the error that you got? Or what did happen? (I never used firebase, but with an error there is a higher change to find the problem :) )

You are right, It will make it easy to solve after seeing that.

Connecting Firebase with Laravel can be accomplished using Firebase's Admin SDK or third-party Laravel packages. Here’s a step-by-step guide to get you started:

Option 1: Using Firebase Admin SDK (Recommended)

1. Install Firebase Admin SDK

Install the official Firebase Admin SDK package via Composer:

composer require kreait/laravel-firebase

2. Publish the Configuration

Publish the configuration file for Firebase:

php artisan vendor:publish --provider="Kreait\Laravel\Firebase\FirebaseServiceProvider"

This will create a configuration file config/firebase.php.

3. Obtain Firebase Service Account Key

• Go to Firebase Console.
• Navigate to Project Settings > Service Accounts.
• Click Generate New Private Key to download the JSON file.

4. Configure Laravel

• Move the JSON file to your Laravel project (e.g., storage/app/firebase-service-account.json).
• Update the FIREBASE_CREDENTIALS in your .env file:

FIREBASE_CREDENTIALS=/absolute/path/to/storage/app/firebase-service-account.json

5. Basic Usage

You can now use Firebase in your Laravel application. Here's an example to interact with Firebase Realtime Database:

use Kreait\Firebase\Factory;
use Kreait\Firebase\Contract\Database;

public function getFirebaseData()
{
    $firebase = (new Factory)
        ->withServiceAccount(config('firebase.credentials.file'))
        ->withDatabaseUri('https://your-project-id.firebaseio.com/');

    $database = $firebase->createDatabase();

    // Fetch data from a Firebase path
    $data = $database->getReference('path/to/your/data')->getValue();

    return response()->json($data);
}

You can also interact with Firebase Authentication, Cloud Messaging, and more. Check the package documentation.

Option 2: Using a Third-Party Laravel Package

Alternatively, you can use a third-party package like laravel-firebase-admin.

Installation

composer require kreait/laravel-firebase

The steps after this are similar to Option 1.

Common Use Cases

1. Firebase Authentication

Authenticate users with Firebase in Laravel:

use Kreait\Firebase\Auth;

public function authenticateUser($idToken)
{
    $auth = app('firebase.auth');

    try {
        $verifiedIdToken = $auth->verifyIdToken($idToken);
        $uid = $verifiedIdToken->claims()->get('sub');

        return response()->json(['uid' => $uid]);
    } catch (\Kreait\Firebase\Exception\Auth\InvalidIdToken $e) {
        return response()->json(['error' => 'Invalid token'], 401);
    }
}

2. Firebase Cloud Messaging (FCM)

Send push notifications using Firebase:

use Kreait\Firebase\Messaging\CloudMessage;

public function sendNotification()
{
    $messaging = app('firebase.messaging');

    $message = CloudMessage::fromArray([
        'token' => 'user-device-token',
        'notification' => ['title' => 'Hello!', 'body' => 'This is a test notification.'],
    ]);

    $messaging->send($message);
}

Debugging Tips

1. Verify the JSON Path: Ensure the FIREBASE_CREDENTIALS path in .env is correct and points to the service account file.
2. Database URI: Ensure you specify the correct database URL in your Firebase project.
3. Enable Services: Check that the Firebase services you’re using (like Realtime Database, Firestore, or FCM) are enabled in the Firebase console.
