Requirements

Slim 4 requires PHP 7.2 or greater. The current Ubuntu LTS and Debian stable include 7.4, so this requirement is satisfied on up to date servers.

Installation

Core

composer require slim/slim:"4.*"
composer require slim/psr7

Additional libraries

composer require filp/whoops
composer require twig/twig
composer require twig/intl-extra
composer require slim/twig-view
composer require doctrine/orm
composer require vlucas/phpdotenv
composer require php-di/php-di --with-all-dependencies
composer require phpunit/phpunit --dev

Directories

mkdir public
mkdir src
mkdir templates
mkdir tests

.gitignore

vendor/

composer.json autoloader

"autoload": {
    "psr-4": {
        "App\\": "src/"
    }
},
"autoload-dev": {
    "psr-4": {
        "App\\Test\\": "tests/"
    }
}

Run composer dump-autoload to generate the autoloader.

.env file

APP_DEFAULT_TIMEZONE="Europe/London"

templates/base.twig.html

<!doctype html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>{{ block('title') }}</title>
    <link rel="stylesheet" href="/css/pure-min.css">
  </head>
  <body>
    {{ block('content') }}
  </body>
</html>

templates/index.twig.html

 {% extends 'base.twig.html' %}
 {% block content %}
   <p>Hello {{ name }}</p>
 {% endblock %}

public/index.php

<?php

declare(strict_types = 1);

use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;
use DI\ContainerBuilder;
use Slim\Factory\AppFactory;
use Slim\Views\Twig;
use Slim\Views\TwigMiddleware;

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

$dotenv = Dotenv\Dotenv::createImmutable(__DIR__);
$dotenv->load();

date_default_timezone_set($_ENV['APP_DEFAULT_TIMEZONE']);

$containerBuilder = new Container();
AppFactory::setContainer($container);

$app = AppFactory::create();

$app->addRoutingMiddleware();
$app->addBodyParsingMiddleware();
$app->addErrorMiddleware(true, true, true);

$app->get('/hello/[{name}]', function(
  ServerRequestInterface $request,
  ResponseInterface $response,
  array $args
): ResponseInterface {
  $name = $args['name'] ?? 'unknown';
  $response->getBody()->write("hello $name");
  return $response;
});

$app->run();

Slim Skeleton

composer create-project slim/slim-skeleton my-app

Adopting in a legacy project

How to add Slim to an existing project which doesn't use a framework. Slim is probably the only actively maintained framework where this is possible, as Laravel and Symfony both expect you to use them exclusively.
