Four Seasons of Silex

Transcript

3. Put this in your pipe require 'sinatra' ! get '/hi' do "Hello World!" end
4. and source 'https://rubygems.org' gem 'sinatra'
5. smoke it $ bundle install $ bundle exec ruby hi.rb == Sinatra has taken the stage ... >> Listening on 0.0.0.0:4567 $ curl localhost:4567/hi Hello World!
8. get '/hello/:name' do "Hello #{params[:name]}!" end
9. get '/' do haml '%div.title Hello World' end
10. get '/' do haml :index end ! __END__ ! @@ layout %html = yield ! @@ index %div.title Hello world.
11. before do # ... end ! after do # ... end
12. Why? • How do we build large systems? • We don’t. • Micro-SOA • HTTP APIs
13. Questions? sinatrarb.com
15. Chunking
16. Context more abstract more concrete
17. Frameworks Zero
18. Frameworks Zero Don’t re- invent the wheel! You’re bloated and buggy!
19. Frameworks Zero Conventions Libraries Wiring
20. Conventions Libraries Wiring Coding standard Directory layout Community
21. Conventions Libraries Wiring Routing ORM Templating etc.
22. Conventions Libraries Wiring Base config Library glue Bootstrap
23. Conventions Libraries Wiring Frameworks Zero
24. Conventions Libraries Wiring Frameworks Zero Because downloading stuff is hard!

31. Add what you need
32. Minimal interface: ~5 classes
33. So… what is it?
34. Glorified Router
35. $app = new Silex\Application();
 
 $app->get('/', function () {
 return "Hello world!";
 }); ! $app->run();
36. $app->get('/blog/{id}', 'Blog::showPost'); ! $app->post('/blog/{id}', 'Blog::createPost'); ! $app->put('/blog/{id}', function ($id) {
 ...
 })
 ->assert('id', '\d+');
37. $app->before(function () {
 ...
 });
 
 $app->after(function () {
 ...
 });
 
 $app->finish(function () {
 ...
 });
38. use Symfony\Component\HttpFoundation\Response;
 
 $app->error(function (\Exception $e, $code) {
 return new Response('Whoops!', $code);
 });
39. $app->redirect('/hello'); ! $app->json($data); ! $app->sendFile($file);
40. Dependency Injection Container
41. class Application extends Pimple
42. $app['routes'] ! $app['url_matcher'] ! $app['kernel']
43. User Interface
    for Symfony2
44. http-kernel http-foundation event-dispatcher routing silex

55. HttpKernel Request Response request controller response

58. use Symfony\Component\EventDispatcher\EventDispatcher; $dispatcher = new EventDispatcher();

63. $route = (new Route('/foo')) ->setDefault('_controller', ...) ->setRequirement('_method', 'POST');
64. use Symfony\Component\HttpFoundation\Request; $request = Request::createFromGlobals(); $response = $kernel->handle($request); $response->send();
