## Installation

This package requires Laravel 5.8 and higher or Lumen 5.8 and higher.

```bash
composer require kreait/laravel-firebase
```

If you use Lumen or don't use Laravel's package auto-discovery, add the following service provider in 
`config/app.php` (Laravel) or `bootstrap/app.php` (Lumen):

### Laravel

```php
<?php
// config/app.php
return [
    // ...
    'providers' => [
        // ...
        Kreait\Laravel\Firebase\ServiceProvider::class
    ]
    // ...   
];
```

### Lumen

```php
<?php
// bootstrap/app.php

$app->register(Kreait\Laravel\Firebase\ServiceProvider::class);
```

## Configuration

In order to access a Firebase project and its related services using a server SDK, requests must be authenticated.
For server-to-server communication this is done with a Service Account.

The package uses auto discovery to find the credentials needed for authenticating requests to the Firebase APIs
by inspecting certain environment variables and looking into Google's well known path(s).

If you don't already have generated a Service Account, you can do so by following the instructions from the 
official documentation pages at https://firebase.google.com/docs/admin/setup#initialize_the_sdk.

Once you have downloaded the Service Account JSON file, you can use it to configure the package by specifying
the environment variable `FIREBASE_CREDENTIALS` in your `.env` file:

```
FIREBASE_CREDENTIALS=/full/path/to/firebase_credentials.json
# or
FIREBASE_CREDENTIALS=relative/path/to/firebase_credentials.json
```

For further configuration, please see [config/firebase.php](config/firebase.php). You can modify the configuration
by copying it to your local `config` directory:

```bash
# Laravel
php artisan vendor:publish --provider="Kreait\Laravel\Firebase\ServiceProvider" --tag=config

# Lumen
mkdir -p config
cp vendor/kreait/firebase-laravel/config/firebase.php config/firebase.php
```

done for you with the Laravel Service Provider. Use Dependency Injection, the Facades or the `app()` helper instead**
