Automatic REST API for SlimPHP 4 (minimal)

26 Sep 2019 - by 'Maurits van der Schee'

Last month we showed how to use PHP-CRUD-API (2k stars) as a library executed on an endpoint in the SlimPHP 4 framework (10k stars). In the previous post we used the recommended way to set up a SlimPHP 4 project and in this post we take a minimal approach (using as little code as possible).

Install SlimPHP4

We download composer and use it to install the two projects:

wget https://getcomposer.org/composer.phar
php composer.phar require slim/slim:^4
php composer.phar require mevdschee/php-crud-api

This is all that is needed.

Create an index.php

Now add the following code to a file named index.php:


use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Slim\Factory\AppFactory;
use \Tqdev\PhpCrudApi\Config;
use \Tqdev\PhpCrudApi\Api;

require __DIR__ . '/vendor/autoload.php';

// Instantiate App
$app = AppFactory::create();

// Add this handler for PHP-CRUD-API:
$app->any('/api[/{params:.*}]', function (Request $request, Response $response) {
    $config = new Config([
        'username' => 'php-crud-api',
        'password' => 'php-crud-api',
        'database' => 'php-crud-api',
        'basePath' => '/api',
    $api = new Api($config);
    $response = $api->handle($request);
    return $response;


And run it using the following command:

php -S localhost:8080

You should be able to see the API running at:


Replace "posts" with the name of any table in your database. If everything works as expected, then you should see the contents of the table in JSON format.
