The console

Every Symfony app includes a console. Writing your own commands takes one class: the #[AsCommand] attribute registers it and gives it a name.

Arguments and options are declared as method parameters with attributes, and SymfonyStyle gives you beautiful output, tables, progress bars and interactive questions for free.

The console also comes packed with built-in commands: inspect routes and services, clear caches, run migrations... and the make:* commands, which generate controllers, entities, forms, tests and more, so you never start from a blank file.
