# M2 Issue #14: User Preferences Storage - Completion Report
|
|
|
|
**Status:** ✅ **COMPLETED**
|
|
|
|
**Task:** Implement User Preferences Storage (#14)
|
|
|
|
## Implementation Summary
|
|
|
|
Successfully implemented a complete user preferences storage system for the Mosaic Stack API.
|
|
|
|
### 1. Database Schema ✅
|
|
|
|
Added `UserPreference` model to Prisma schema (`apps/api/prisma/schema.prisma`):
|
|
|
|
- id (UUID primary key)
|
|
- userId (unique foreign key to User)
|
|
- theme (default: "system")
|
|
- locale (default: "en")
|
|
- timezone (optional)
|
|
- settings (JSON for additional custom preferences)
|
|
- updatedAt (auto-updated timestamp)
|
|
|
|
**Relation:** One-to-one relationship with User model.
|
|
|
|
### 2. Migration ✅
|
|
|
|
Created and applied migration: `20260129225813_add_user_preferences`
|
|
|
|
- Created `user_preferences` table
|
|
- Added unique constraint on `user_id`
|
|
- Added foreign key constraint with CASCADE delete
|
|
|
|
### 3. API Endpoints ✅
|
|
|
|
Created REST API at `/api/users/me/preferences`:
|
|
|
|
**GET /api/users/me/preferences**
|
|
|
|
- Retrieves current user's preferences
|
|
- Auto-creates default preferences if none exist
|
|
- Protected by AuthGuard
|
|
|
|
**PUT /api/users/me/preferences**
|
|
|
|
- Updates user preferences (partial updates supported)
|
|
- Creates preferences if they don't exist
|
|
- Protected by AuthGuard
|
|
|
|
### 4. Service Layer ✅
|
|
|
|
Created `PreferencesService` (`apps/api/src/users/preferences.service.ts`):
|
|
|
|
- `getPreferences(userId)` - Get or create default preferences
|
|
- `updatePreferences(userId, updateDto)` - Update or create preferences
|
|
- Proper type safety with Prisma types
|
|
- Handles optional fields correctly with TypeScript strict mode
|
|
|
|
### 5. DTOs ✅
|
|
|
|
Created Data Transfer Objects:
|
|
|
|
**UpdatePreferencesDto** (`apps/api/src/users/dto/update-preferences.dto.ts`):
|
|
|
|
- theme: optional, validated against ["light", "dark", "system"]
|
|
- locale: optional string
|
|
- timezone: optional string
|
|
- settings: optional object for custom preferences
|
|
- Full class-validator decorators for validation
|
|
|
|
**PreferencesResponseDto** (`apps/api/src/users/dto/preferences-response.dto.ts`):
|
|
|
|
- Type-safe response interface
|
|
- Matches database schema
|
|
|
|
### 6. Module Integration ✅
|
|
|
|
- Created `UsersModule` with proper NestJS structure
|
|
- Registered in `app.module.ts`
|
|
- Imports PrismaModule and AuthModule
|
|
- Exports PreferencesService for potential reuse
|
|
|
|
## File Structure
|
|
|
|
```
|
|
apps/api/src/users/
|
|
├── dto/
|
|
│ ├── index.ts
|
|
│ ├── preferences-response.dto.ts
|
|
│ └── update-preferences.dto.ts
|
|
├── preferences.controller.ts
|
|
├── preferences.service.ts
|
|
└── users.module.ts
|
|
```
|
|
|
|
## Code Quality
|
|
|
|
✅ TypeScript strict mode compliance
|
|
✅ Proper error handling (UnauthorizedException)
|
|
✅ Consistent with existing codebase patterns
|
|
✅ Following NestJS best practices
|
|
✅ Proper validation with class-validator
|
|
✅ JSDoc comments for documentation
|
|
|
|
## Testing Recommendations
|
|
|
|
To test the implementation:
|
|
|
|
1. **GET existing preferences:**
|
|
|
|
```bash
|
|
curl -H "Authorization: Bearer <token>" \
|
|
http://localhost:3000/api/users/me/preferences
|
|
```
|
|
|
|
2. **Update preferences:**
|
|
```bash
|
|
curl -X PUT \
|
|
-H "Authorization: Bearer <token>" \
|
|
-H "Content-Type: application/json" \
|
|
-d '{"theme":"dark","locale":"es","timezone":"America/New_York"}' \
|
|
http://localhost:3000/api/users/me/preferences
|
|
```
|
|
|
|
## Notes
|
|
|
|
- Migration successfully applied to database
|
|
- All files following TypeScript coding standards from `~/.claude/agent-guides/typescript.md`
|
|
- Backend patterns follow `~/.claude/agent-guides/backend.md`
|
|
- Implementation complete and ready for frontend integration
|
