README

This package allows you to store a copy of a Laravel model inside a Firestore collection, keeping it in sync with your application's database.

Installation

Install the package using Composer:

composer require firevel/firestore-mirror

Then, add the \Firevel\FirestoreMirror\HasFirestoreMirror trait to any model you want to mirror in Firestore:

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

class User extends Model
{
    use HasFirestoreMirror;
}

Configuration

Firestore Collection

By default, each model will be stored in a Firestore collection that matches its database table name. To customize the collection name, define the $firestoreCollection property in your model:

/**
 * Firestore collection name.
 *
 * @var string
 */
public $firestoreCollection = 'users';

Alternatively, you can define a getFirestoreCollectionName() method to dynamically determine the collection name:

/**
 * Get firestore collection used for mirroring.
 *
 * @return string
 */
public function getFirestoreCollectionName()
{
    if (empty($this->firestoreCollection)) {
        return $this->getTable();
    }

    return $this->firestoreCollection;
}

Firestore Document

To customize the document schema stored in Firestore, define a toFirestoreDocument() method in your model. By default, all model attributes are converted to an array:

/**
 * Convert the model to a Firestore document.
 *
 * @return array
 */
public function toFirestoreDocument()
{
    return $this->attributesToArray();
}

Firestore Document ID

By default, the document ID in Firestore matches the model’s primary key. You can customize this by defining a getFirestoreDocumentId() method:

/**
 * Get the Firestore document ID used for mirroring.
 *
 * @return mixed
 */
public function getFirestoreDocumentId()
{
    return $this->getKey(); // Default: model's primary key
}

Usage

Once the trait is added, the package will automatically mirror changes in your model to Firestore. The following actions trigger updates:

• Creating a new model instance
• Updating an existing model
• Deleting a model instance (removes the document from Firestore)
