# Expo Architect

Create Expo React Native apps with:

- **Framework:** Expo SDK 54 + React Native 0.83 + TypeScript
- **Navigation:** Expo Router (file-based routing)
- **Auth:** Clerk authentication (optional)
- **UI:** NativeWind (Tailwind for RN) or StyleSheet
- **Quality:** Biome linting + TypeScript strict mode
- **Package Manager:** bun

## What Makes This Different

Generates **working mobile apps**, not empty scaffolds:

- Complete navigation structure with working screens
- Optional Clerk authentication flow
- Real UI components with proper styling
- API client integration ready
- Runs immediately with `bun start`

## Workflow Summary

1. **PRD Brief Intake** - Extract app type, screens, features, auth needs
2. **Auth Setup** (if requested) - Clerk provider, sign-in/sign-up screens
3. **Screen Generation** - Tab or stack-based navigation
4. **Component Generation** - UI components, entity components, layouts
5. **Quality Setup** - Biome, TypeScript strict, path aliases
6. **Verification** - Run quality gate, report results

## Usage

```bash
# Create app with PRD-style prompt
python3 scripts/init-expo.py \
  --root ~/www/myapp \
  --name "My App" \
  --brief "A fitness tracker where users can log workouts"

# With specific options
python3 scripts/init-expo.py \
  --root ~/www/myapp \
  --name "My App" \
  --tabs "Home,Workouts,Profile" \
  --auth
```
