# Copenhagen Truck Wash API

Backend API for Copenhagen Truck Wash services.

## Architecture & Stack
- **Edge Proxy:** [Traefik 2.11](https://doc.traefik.io/traefik/) (Handles TLS termination, routing, and rate limiting).
- **Web Server:** [Caddy 2.7](https://caddyserver.com/) (Serves the PHP application via FastCGI).
- **PHP Runtime:** PHP 8.2-FPM (Scale out with workers `php1` to `php5`).
- **Cache/Queue:** Redis 7.
- **Observability:** Jaeger (Tracing), Prometheus (Metrics).

## Getting Started

### Prerequisites
- Docker Desktop 4.x+
- PHP 8.2 CLI (optional, for host-side testing)

### Local Development
To bring up the minimal development stack (Traefik, Redis, MySQL debug DB, Caddy, and one PHP worker):
```powershell
docker compose up -d traefik redis mysql-debug php1 caddy
```

The API is accessible at:
- `http://localhost`
- `https://localhost` (using Traefik default cert)
- `http(s)://localhost/api/` (proxied with `/api` prefix stripped)

To start all services including multiple PHP workers and development tools (Jaeger, Portainer):
```powershell
docker compose --profile dev up -d
```

### Configuration
Configuration is primarily managed via environment variables.
- The application root is located at `services/nginx/app`.
- `services/nginx/app/config.php` loads configuration from the environment (requires `USE_ENV=true`).
- `php1` performs an automatic `composer install` on startup if `AUTO_COMPOSER_INSTALL=true`.

## Testing

The project now uses [Pest](https://pestphp.com/) as the primary test runner in `services/nginx/app`.

### Running Tests
All commands are run from `services/nginx/app`:

```powershell
composer test
composer test:unit
composer test:integration
composer test:coverage
```

Integration tests are opt-in and should be run with required services available:

```powershell
$env:RUN_INTEGRATION_TESTS='1'
composer test:integration
```

### Run Tests Against A Cloned Live DB (Docker-Isolated)
Use the helper scripts in `scripts/` to:
1. Clone the configured live DB into a local MySQL Docker container.
2. Start an isolated Redis container.
3. Run tests in a separate temporary PHP Docker container pointed at that clone.

PowerShell:
```powershell
powershell -ExecutionPolicy Bypass -File .\scripts\clone-live-db-and-test.ps1 -Force
```

Bash:
```bash
FORCE=1 ./scripts/clone-live-db-and-test.sh
```

Optional overrides:
- Test command: `-TestCommand "composer test:integration"` or `TEST_COMMAND="composer test:integration"`
- Keep containers after run: `-KeepContainers` or `KEEP_CONTAINERS=1`
- Skip image build: `-SkipBuild` or `SKIP_BUILD=1`
- Force image rebuild: `-ForceBuild` or `FORCE_BUILD=1`

### Clone Live DB Into `mysql-debug` Service
To refresh the docker-compose debug DB from live credentials in `.env`:

PowerShell:
```powershell
powershell -ExecutionPolicy Bypass -File .\scripts\clone-live-to-debug-db.ps1 -Force
```

Bash:
```bash
FORCE=1 ./scripts/clone-live-to-debug-db.sh
```

### Test Layout
- `tests/Unit/*`: isolated unit and route-level behavior tests.
- `tests/Integration/*`: Redis/DB-backed tests intended for Docker/CI environments.
- `tests/<legacy-domain>/*`: legacy procedural scripts retained during migration; keep them runnable until matching Pest coverage exists.

## Logs & Monitoring
- **Logs:** `docker compose logs -f [service_name]` (e.g., `php1`, `caddy`, `traefik`).
- **Traefik Dashboard:** `http://traefik.localhost` (available in dev).
- **Jaeger (Tracing):** `http://localhost:16686` (when running with `--profile dev`).
- **Portainer:** `http://localhost:9000` (when running with `--profile dev`).
