How do you use Slim Framework with a serverless database service?

Here’s a minimal steps guide for using Slim Framework with a serverless database:

1. Install Database Client

  • For Aurora Serverless (MySQL):

Example

composer require ext-pdo_mysql

For Google Firestore:

Example

composer require google/cloud-firestore

2. Set Up Database Connection

  • Aurora Serverless (MySQL):

Example

<?php
$container['db'] = function () {
    $dsn = "mysql:host=" . getenv('DB_HOST') . ";dbname=" . getenv('DB_NAME');
    return new PDO($dsn, getenv('DB_USERNAME'), getenv('DB_PASSWORD'));
};
?>

Google Firestore:

Example

<?php
use Google\Cloud\Firestore\FirestoreClient;
$container['db'] = function () {
    return new FirestoreClient(['projectId' => getenv('GOOGLE_PROJECT_ID')]);
};
?>

3. Perform CRUD Operations

  • Aurora Serverless (MySQL):

Example

<?php
$app->get('/items', function ($request, $response) {
    $stmt = $this->db->query("SELECT * FROM items");
    return $response->withJson($stmt->fetchAll());
});
?>

Google Firestore:

Example

<?php
$app->get('/items', function ($request, $response) {
    $items = $this->db->collection('items')->documents();
    return $response->withJson($items->rows());
});
?>

4. Deploy to Serverless

  • Deploy Slim app on platforms like AWS Lambda or Google Cloud Run.

5. Secure Credentials

  • Store DB credentials in environment variables or use a secrets manager.
