and source 'https://rubygems.org' gem 'sinatra'

Add what you need

Minimal interface: ~5 classes

So… what is it?

Glorified Router

$app = new Silex\Application();
 
 $app->get('/', function () {
 return "Hello world!";
 }); ! $app->run();

$app->get('/blog/{id}', 'Blog::showPost'); ! $app->post('/blog/{id}', 'Blog::createPost'); ! $app->put('/blog/{id}', function ($id) {
 ...
 })
 ->assert('id', '\d+');

$app->before(function () {
 ...
 });
 
 $app->after(function () {
 ...
 });
 
 $app->finish(function () {
 ...
 });

use Symfony\Component\HttpFoundation\Response;
 
 $app->error(function (\Exception $e, $code) {
 return new Response('Whoops!', $code);
 });

$app->redirect('/hello'); ! $app->json($data); ! $app->sendFile($file);

Dependency Injection Container
