Automatically sync your Laravel Eloquent models to Google Firestore collections in real-time. This package provides a seamless way to mirror your database records to Firestore, enabling powerful real-time features and offline capabilities for your applications.

Features

  • 🔄 Automatic Synchronization: Changes to your Eloquent models are automatically reflected in Firestore
  • 🚀 Batch Operations: Efficiently sync entire collections using Firestore's batch API
  • 🎯 Flexible Configuration: Customize collection names, document IDs, and document structure
  • 🧩 Simple Integration: Just add a trait to your existing Eloquent models
  • âš¡ Performance Optimized: Uses Firestore batch operations for bulk updates

Requirements

Installation

Install the package using Composer:

composer require firevel/firestore-mirror

Quick Start

Add the HasFirestoreMirror trait to any Eloquent model you want to sync with Firestore:

use Firevel\FirestoreMirror\HasFirestoreMirror;
use Illuminate\Database\Eloquent\Model;

class User extends Model
{
    use HasFirestoreMirror;
    
    // Optional: Customize the Firestore collection name
    public $firestoreCollection = 'users';
    
    // Optional: Customize the document structure
    public function toFirestoreDocument()
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
            'email' => $this->email,
            'created_at' => $this->created_at->toIso8601String(),
        ];
    }
}

That's it! Your User model will now automatically sync to Firestore whenever you create, update, or delete records.

Configuration

Customizing Collection Names

By default, the Firestore collection name matches your model's database table name. You can customize this in two ways:

Static Collection Name

class User extends Model
{
    use HasFirestoreMirror;
    
    public $firestoreCollection = 'app_users';
}

Dynamic Collection Name

class User extends Model
{
    use HasFirestoreMirror;
    
    public function getFirestoreCollectionName()
    {
        return 'users_' . $this->tenant_id;
    }
}

Customizing Document Structure

Control exactly what data gets synced to Firestore by overriding the toFirestoreDocument() method:

public function toFirestoreDocument()
{
    return [
        'id' => $this->id,
        'name' => $this->name,
        'email' => $this->email,
        'role' => $this->role,
        'metadata' => [
            'last_login' => $this->last_login?->toIso8601String(),
            'verified' => $this->email_verified_at !== null,
        ],
        'updated_at' => $this->updated_at->toIso8601String(),
    ];
}

Customizing Document IDs

By default, the Firestore document ID matches your model's primary key. Override this behavior:

public function getFirestoreDocumentId()
{
    return $this->uuid; // Use a UUID field instead
}

Usage

Automatic Syncing

Once you've added the HasFirestoreMirror trait, your models will automatically sync to Firestore on these events:

  • Create: New model instances are added to Firestore
  • Update: Changes to existing models are synced to Firestore
  • Delete: Deleted models are removed from Firestore
// This will automatically create a document in Firestore
$user = User::create([
    'name' => 'John Doe',
    'email' => 'john@example.com'
]);

// This will automatically update the document in Firestore
$user->update(['name' => 'Jane Doe']);

// This will automatically delete the document from Firestore
$user->delete();

Manual Syncing

You can manually sync individual models:

$user = User::find(1);
$user->mirrorToFirestore(); // Manually sync to Firestore

Batch Syncing Collections

The package provides a powerful mirrorToFirestore() collection macro for efficiently syncing multiple models at once using Firestore's batch operations:

// Sync all users to Firestore
User::all()->mirrorToFirestore();

// Sync filtered collections
User::where('active', true)->get()->mirrorToFirestore();

// Sync users with relationships loaded
User::with('posts')->get()->mirrorToFirestore();

// Sync paginated results
User::paginate(100)->mirrorToFirestore();

The batch operation is atomic - either all documents are synced successfully, or none are.

Deleting from Firestore

To manually delete a model from Firestore without deleting it from your database:

$user = User::find(1);
$user->deleteFromFirestore();

Advanced Usage

Conditional Syncing

You might want to sync only certain models based on conditions:

class User extends Model
{
    use HasFirestoreMirror;
    
    public function shouldMirrorToFirestore()
    {
        return $this->is_active && $this->email_verified_at !== null;
    }
    
    public function mirrorToFirestore()
    {
        if ($this->shouldMirrorToFirestore()) {
            return parent::mirrorToFirestore();
        }
        
        return $this;
    }
}

Multi-Tenant Applications

For multi-tenant applications, you can dynamically set collection names:

class Order extends Model
{
    use HasFirestoreMirror;
    
    public function getFirestoreCollectionName()
    {
        return "tenants/{$this->tenant_id}/orders";
    }
}
