Migrate from Prisma to Drizzle ORM

[Copilot]

Migration Plan: Prisma to Drizzle ORM

Understanding

The project currently uses:

• Prisma ORM with PostgreSQL database
• Neon serverless database adapter
• 4 models: User, AttendanceRoom, AttendanceRecord, Attendant
• Multiple server actions using Prisma client
• Prisma-specific error handling

Migration Checklist

• Install Drizzle dependencies (drizzle-orm, drizzle-kit, postgres)
• Create Drizzle schema file based on existing Prisma schema
• Create Drizzle configuration file (drizzle.config.ts)
• Create database client file with Drizzle setup
• Migrate all database queries from Prisma to Drizzle:
  • src/lib/auth.ts - User queries
  • src/app/(internal)/(protected)/actions.tsx - AttendanceRoom CRUD
  • src/app/(internal)/(protected)/(sidebar)/attendance/[id]/actions.tsx - Room and record queries
  • src/app/(public)/attendance/[id]/take/actions.tsx - Attendant and record operations
• Update error handling to replace Prisma-specific errors
• Update package.json scripts (remove prisma generate/migrate, add drizzle scripts)
• Fix all TypeScript compilation errors
• Update all test files to use Drizzle ORM
• Remove Prisma dependencies and files (prisma, @prisma/client, @prisma/adapter-neon)
• Update component files to use Drizzle types
• Address code review feedback
• Use pnpm instead of npm (removed package-lock.json, updated pnpm-lock.yaml)

Summary

Successfully migrated the entire codebase from Prisma to Drizzle ORM:

• Replaced all Prisma queries with Drizzle equivalents
• Updated error handling to use PostgreSQL error codes
• Migrated all tests to use Drizzle
• Removed all Prisma dependencies and files
• Fixed all TypeScript compilation errors
