# config ## Purpose Symfony application configuration: bundle registration, service wiring, routing entry points, and per-bundle YAML config. ## Key Files | File | Description | |------|-------------| | `bundles.php` | Registered bundles per environment (Framework, Doctrine, Migrations, Twig, Security, Monolog, Stimulus, Turbo, KnpPaginator, Maker, Fixtures) | | `services.yaml` | Service container: autowire/autoconfigure defaults, `App\` from `src/`; explicit config for `AppExtension` (Twig tag) and `PayPalService` (injects `PAYPAL_CLIENT_ID`/`SECRET`/`MODE` env vars) | | `routes.yaml` | Loads controller routes via attribute resolver from `src/Controller/` | | `preload.php` | OPcache preload file | ## Subdirectories | Directory | Purpose | |-----------|---------| | `packages/` | Per-bundle configuration YAML (see `packages/AGENTS.md`) | | `routes/` | Route config for framework/security/web_profiler (see `routes/AGENTS.md`) | ## For AI Agents ### Working In This Directory - New services usually need no entry here (autowiring covers `src/`). Add explicit config only for constructor args that can't be autowired (see the `PayPalService` env-var example). - Run `php bin/console cache:clear` after editing any config. - To add a route, prefer `#[Route]` attributes on the controller — `routes.yaml` already scans `src/Controller/`. ### Common Patterns - Env vars are referenced as `%env(NAME)%` and defined in `.env` (see root `AGENTS.md` re: committed secrets). ## Dependencies ### Internal - Wires everything in `src/`. ### External - Symfony DependencyInjection, all bundles listed in `bundles.php`.
