## Phase 1: Foundation & Authentication 🚧 IN PROGRESS
|
||||
|
||||
### Completed Tasks
|
||||
|
||||
#### Database Schema & Migrations ✅
|
||||
- ✅ **TypeORM Configuration**: Database module with async configuration
|
||||
- ✅ **Entity Models Created**:
|
||||
- `User` - Core user authentication entity with email, password hash, locale, timezone
|
||||
- `DeviceRegistry` - Device fingerprinting with trusted device management
|
||||
- `Family` - Family grouping with share codes
|
||||
- `FamilyMember` - Junction table with roles (parent/caregiver/viewer) and permissions
|
||||
- `Child` - Child profiles with medical info and soft deletes
|
||||
- `RefreshToken` (via migration) - JWT refresh token management
|
||||
|
||||
- ✅ **Database Migrations Executed**:
|
||||
- **V001**: Core authentication tables (users, device_registry)
|
||||
- **V002**: Family structure (families, family_members, children)
|
||||
- **V003**: Refresh tokens table for JWT authentication
|
||||
|
||||
- ✅ **Migration Infrastructure**:
|
||||
- Migration tracking with `schema_migrations` table
|
||||
- Automated migration runner script
|
||||
- NPM script: `npm run migration:run`
|
||||
|
||||
#### Database Tables Verified
|
||||
```
|
||||
users - User accounts
|
||||
device_registry - Trusted devices per user
|
||||
families - Family groupings
|
||||
family_members - User-family relationships with roles
|
||||
children - Child profiles
|
||||
refresh_tokens - JWT refresh token storage
|
||||
schema_migrations - Migration tracking
|
||||
```
|
||||
|
||||

|
||||
- ⏳ Implement device fingerprinting validation
|
||||
- ⏳ Create Passport JWT strategy
|
||||
- ⏳ Add authentication guards
|
||||

## Key Decisions & Architecture
|
||||
|
||||
### Database Design
|
||||
- **ID Generation**: Custom nanoid-style IDs with prefixes (usr_, dev_, fam_, chd_)
|
||||
- **Soft Deletes**: Children have `deleted_at` for data retention
|
||||
- **JSONB Fields**: Flexible storage for permissions, medical info
|
||||
- **Indexes**: Optimized for common queries (email lookups, family relationships)
|
||||
|
||||
### Authentication Strategy
|
||||
- **JWT with Refresh Tokens**: Short-lived access tokens (1h), long-lived refresh tokens (7d)
|
||||
- **Device Fingerprinting**: Track and trust specific devices
|
||||
- **Multi-Device Support**: Users can be logged in on multiple trusted devices
|
||||
|
||||
### Security Considerations
|
||||
- Password hashing with bcrypt
|
||||
- Device-based authentication
|
||||
- Refresh token rotation
|
||||
- Token revocation support
|
||||
- COPPA/GDPR compliance preparation
|
||||

|
||||
|
||||
## Next Steps
|
||||
|
||||
### Immediate (Current Session)
|
||||
1. Create authentication module with bcrypt
|
||||
2. Implement JWT strategies (access + refresh)
|
||||
3. Build authentication controller with all endpoints
|
||||
4. Add device fingerprinting service
|
||||
5. Create authentication guards
|
||||
|
||||
### Next Session
|
||||
1. Mobile authentication UI screens
|
||||
2. i18n setup with 5 languages
|
||||
3. Email verification flow
|
||||
4. Password reset functionality

|
||||
## Commands Reference
|
||||
|
||||
### Backend
|
||||
```bash
|
||||
cd maternal-app-backend
|
||||
|
||||
# Start development server
|
||||
npm run start:dev
|
||||
|
||||
# Run migrations
|
||||
npm run migration:run
|
||||
|
||||
# Run tests
|
||||
npm test
|
||||
```
|
||||
|
||||
### Mobile
|
||||
```bash
|
||||
cd maternal-app
|
||||
|
||||
# Start Expo
|
||||
npm start
|
||||
|
||||
# Run on iOS
|
||||
npm run ios
|
||||
|
||||
# Run on Android
|
||||
npm run android
|
||||
```
|
||||
|
||||
### Infrastructure
|
||||
```bash
|
||||
# Start all services
|
||||
docker compose up -d
|
||||
|
||||
# Check service status
|
||||
docker compose ps
|
||||
|
||||
# View logs
|
||||
docker compose logs -f
|
||||
|
||||
# Stop all services
|
||||
docker compose down
|
||||
```
|
||||
|
||||
### Database
|
||||
```bash
|
||||
# Connect to PostgreSQL
|
||||
docker exec -it maternal-postgres psql -U maternal_user -d maternal_app
|
||||
|
||||
# List tables
|
||||
\dt
|
||||
|
||||
# Describe table
|
||||
\d users
|
||||
```
|
||||

|
||||
|
||||
## Technical Debt / Notes
|
||||
|
||||
1. **Node Version Warning**: React Native Expo shows warnings for Node 18.x (prefers 20+), but it works fine for development
|
||||
2. **Security**: All default passwords must be changed before production
|
||||
3. **ID Generation**: Using custom nanoid implementation - consider using proper nanoid package
|
||||
4. **Migration Strategy**: Currently using raw SQL - consider switching to TypeORM migrations for better TypeScript integration
|
||||
5. **Error Handling**: Need to implement standardized error codes as per error-logging documentation
|
||||

|
||||
|
||||
**Last Updated**: Phase 1 - Database setup completed, authentication module in progress
