MicroframeworksWednesday, March 2, 2011

What? • Bare bones • Routes mapped to actions • The ‘C’ of ‘MVC’ • REST • Single ﬁle appWednesday, March 2, 2011

Why? • Frameworks are: • heavy • verbose • complexWednesday, March 2, 2011

Sometimes a full-stack framework is too much for a simple task.Wednesday, March 2, 2011

Dynamic RoutingWednesday, March 2, 2011

$app->get(/hello/{name}, function($name) { return "Hello $name!"; });Wednesday, March 2, 2011

Before & AfterWednesday, March 2, 2011

$app->before(function() use ($conn) { $conn = new PDO(mysql:dbname=myapp); }); $app->get(/, function() use ($conn) { $usernames = array(); $sql = SELECT * FROM user ORDER BY email; foreach ($conn->query($sql) as $row) { $usernames[] = $row[username]; } return implode(<br />, $usernames); }); $app->after(function() use ($conn) { $conn = null; });Wednesday, March 2, 2011

RESTWednesday, March 2, 2011

use SymfonyComponentHttpFoundationResponse; $app->post(/blog/post/{id}, function($id) use ($app) { $request = $app->getRequest(); $id = (int) $id; $filename = __DIR__."/data/$id.json"; if (file_exists($filename)) { return new Response(, 409); } file_put_contents($filename, json_encode(array( id => $id, title => $request->get(title), body => $request->get(body), ))); return new Response(, 201); });Wednesday, March 2, 2011

$app->delete(/blog/post/{id}, function($id) { $id = (int) $id; $filename = __DIR__."/data/$id.json"; if (!file_exists($filename)) { return new Response(, 404); } unlink($filename); return new Response(, 200); });Wednesday, March 2, 2011

Errors (Exceptions)Wednesday, March 2, 2011

use MonologLogger; use MonologHandlerFileHandler; use SymfonyComponentHttpKernelExceptionNotFoundHttpException; $log = new Logger(myapp); $log->pushHandler(new FileHandler(__DIR__.log/error.log, Logger::ERROR)); $app->error(function(Exception $e) use ($log) { if ($e instanceof NotFoundHttpException) { return new Response( What you are looking for does not exist., 404); } $log->addError(json_encode(array( class => get_class($e), message => $e->getMessage(), code => $e->getCode(), trace => $e->getTrace(), ))); return new Response(Something very bad happened., 500); });Wednesday, March 2, 2011

How? • Symfony2 • Extends HttpKernel • Event Dispatcher • Routing • Request & ResponseWednesday, March 2, 2011

Experimental Fork • String return value • Syntactic sugar for routes • Before & after hooks • Error handling • Integration testsWednesday, March 2, 2011

MicroKernelBundle • Bulat Shakirzyanow (avalanche123) • More routing ﬂexibility • Uses instance of Kernel • Integrates with Symfony2Wednesday, March 2, 2011

bootstrap.php use ...DependencyInjectionContainerBuilder; use ...DependencyInjectionLoaderYamlFileLoader; use ...ConfigFileLocator; $container = new ContainerBuilder(); $env = getenv(APP_ENV) ?: dev; $loader = new YamlFileLoader($container, new FileLocator(__DIR__)); $loader->load("config.$env.yml");Wednesday, March 2, 2011

conﬁg.dev.yml services: silex: @silex.framework silex.framework: class: SilexFrameworkWednesday, March 2, 2011

app.php $app->get(/user/{id}, function($id) use ($container) { $users = $container->get(mongo.users); $user = $user->findOne(array("_id" => $id)); return new Response( json_encode($user), 200, array(Content-Type => application/json) ); });Wednesday, March 2, 2011

#3 TwigWednesday, March 2, 2011

bootstrap.php use SymfonyComponentClassLoaderUniversalClassLoader; $loader = new UniversalClassLoader(); $loader->registerPrefixes(array( Twig_ => __DIR__ . /vendor/Twig/lib, )); $loader->register(); $twigLoader = new Twig_Loader_Filesystem(/views); $twig = new Twig_Environment($twigLoader, array( cache => /cache/twig, debug => true, ));Wednesday, March 2, 2011

#4 TestingWednesday, March 2, 2011

use SilexWebTestCase; require_once __DIR__./silex.phar; class test extends WebTestCase { public function createApp() { return require __DIR__./app.php; } // tests... }Wednesday, March 2, 2011

public function testAbout() { $client = $this->createClient(); $client->request(GET, /about); $response = $client->getResponse(); $this->assertTrue($response->isOk()); $this->assertContains(trashbin, $response->getContent()); $this->assertContains(github, $response->getContent()); $this->assertContains(igorw, $response->getContent()); }Wednesday, March 2, 2011
