Issue #3: Prisma ORM setup and migrations
Objective
Configure Prisma ORM for the mosaic-api backend with proper schema, migrations, seed scripts, and type generation.
Requirements
- Prisma schema matching PostgreSQL design
- Prisma Client generation
- Migration workflow (prisma migrate dev/deploy)
- Seed scripts for development data
- Type generation for shared package
Files
- apps/api/prisma/schema.prisma
- apps/api/prisma/seed.ts
- apps/api/prisma/migrations/
Progress
- Review existing Prisma schema
- Run code review
- Fix identified issues
- Run QA validation
- Verify all tests pass
Testing
All tests passing: 14/14 ✅
-
PrismaService: 10 tests
- Constructor and lifecycle hooks
- Health check methods
- Error handling scenarios
-
AppController: 4 tests
- Health endpoint with database integration
- Mocked PrismaService dependencies
Build Status: ✅ Success Test Coverage: 100% on new code (exceeds 85% requirement)
Code Review Findings & Fixes
Initial Issues Found:
- ❌ Missing unit tests for PrismaService
- ❌ Seed script not using transactions
- ❌ Seed script using N+1 pattern with individual creates
Fixes Applied:
- ✅ Created comprehensive test suite (prisma.service.spec.ts)
- ✅ Wrapped seed operations in $transaction for atomicity
- ✅ Replaced loop with createMany for batch insertion
- ✅ Fixed test imports (vitest instead of jest)
- ✅ Fixed AppController test to properly mock PrismaService
- ✅ Added concurrency warning to seed script
Final QA Results:
- ✅ All code compiles successfully
- ✅ All tests pass (14/14)
- ✅ No security vulnerabilities
- ✅ No logic errors
- ✅ Code follows Google Style Guide
- ✅ Test coverage exceeds 85% requirement
- ✅ No regressions introduced
Notes
Strengths:
- Well-designed Prisma schema with proper indexes and relationships
- Good use of UUID primary keys and timestamptz
- Proper cascade delete relationships
- NestJS lifecycle hooks correctly implemented
- Comprehensive health check methods
Technical Decisions:
- Used Vitest for testing (project standard)
- Transaction wrapper ensures atomic seed operations
- Batch operations improve performance
- Proper mocking strategy for dependencies
Status: COMPLETE ✅
