  4. 1. The Community 2. HttpKernelInterface 3. Symfony Flex

  5. A Strong Community A growing core team - 17 members

    Amazing support team - many Dedicated doc team - 7 members A growing community of developers - tons
  6. HttpKernelInterface has not changed since 2.0 Last change was before

    2.0 10 years ago Simple interfaces are powerful Standards are powerful BC policy is important namespace Symfony\Component\HttpKernel; use Symfony\Component\HttpFoundation\Request; use Symfony\Component\HttpFoundation\Response; interface HttpKernelInterface { const MASTER_REQUEST = 1; const SUB_REQUEST = 2; /** * Handles a Request to convert it to a Response. */ public function handle(Request $request, int $type = self::MASTER_REQUEST, bool $catch = true); }
  7. Flex enables Components to act as a Framework Standalone Components

    (think PEAR reinvented) FrameworkBundle as a set of default con f i gurations for core features Flex enables any package to feel like a Symfony core feature
  8. RAD?

  9. Security Bootstrap a new project the fast way $ symfony

    new demo $ composer req maker profiler orm validator form security $ vi docker-compose.yml $ docker-compose up -d $ symfony server:start -d $ symfony open:local version: '3' services: database: image: postgres:12-alpine environment: POSTGRES_USER: main POSTGRES_PASSWORD: main POSTGRES_DB: main ports: [5432] mailer: image: schickling/mailcatcher ports: [1025, 1080] Symfony CLI Docker Compose Composer & Flex
  10. The name of the security user class (e.g. User) [User]:

    > Do you want to store user data in the database (via Doctrine)? (yes/no) [yes]: > Enter a property name that will be the unique "display" name for the user (e.g. email, username, uuid) [email]: > Will this app need to hash/check user passwords? Choose No if passwords are not needed or will be checked/hashed by some other system (e.g. a single sign-on server). Does this app need to hash/check user passwords? (yes/no) [yes]: > $ symfony console make:user Maker bundle generates code that you own
  11. What style of authentication do you want? [Empty authenticator]: [0]

    Empty authenticator [1] Login form authenticator > 1 The class name of the authenticator to create (e.g. AppCustomAuthenticator): > AppAuthenticator Choose a name for the controller class (e.g. SecurityController) [SecurityController]: > Do you want to generate a '/logout' URL? (yes/no) [yes]: > $ symfony console make:auth
  12. Creating a registration form for App\Entity\User Do you want to

    add a @UniqueEntity validation annotation on your User class to make sure duplicate accounts aren't created? (yes/no) [yes]: > Do you want to send an email to verify the user's email address after registration? (yes/no) [yes]: > [WARNING] We're missing some important components. Don't forget to install these after you're finished. composer require symfonycasts/verify-email-bundle symfony/mailer What email address will be used to send registration confirmations? e.g. mailer@your-domain.com: > demo@example.com What "name" should be associated with that email address? e.g. "Acme Mail Bot": > Demo Bot Do you want to automatically authenticate the user after registration? (yes/no) [yes]: > $ symfony console make:registration-form
  13. Security Bootstrap a new project the fast way $ symfony

    console make:migration $ symfony console doctrine:migrations:migrate -n
  14. https://127.0.0.1:8000/register $ symfony open:local:webmail

  15. https://127.0.0.1:8000/logout https://127.0.0.1:8000/login

  41. Develop JS code in a Symfony app using plain JS,

    
 standard JS tools and packages, 
 thanks to a few conventions and Flex help UX
  42. The key goal is to enable progressive enhancements Standard HTTP

    SEO friendly Accessible ... and still compatible with VueJS/React/... UX
