Database Migration Complete

Files Created

1. Prisma Schema: prisma/schema.prisma

   • Comprehensive schema with all 18+ models
   • Supports SQLite, PostgreSQL, and MySQL

2. Prisma Client: src/lib/prisma.ts

   • Singleton pattern for Prisma Client
   • Proper cleanup in development mode

3. New Database Layer: src/lib/database-prisma.ts

   • Complete Prisma implementation
   • Maintains exact same API as old database.ts
   • All methods converted from spark.kv to Prisma

4. Migration Script: scripts/migrate-to-prisma.cjs

   • Backs up old database.ts to database-kv-backup.ts
   • Copies database-prisma.ts to database.ts

5. Documentation:

   • docs/PRISMA_MIGRATION.md - Migration guide
   • docs/database/PRISMA_SETUP.md - Setup instructions

Next Steps

Option 1: Automatic Migration (Recommended)

node scripts/migrate-to-prisma.cjs
npm run db:generate
npm run db:push

Option 2: Manual Migration

# 1. Backup current database.ts
cp src/lib/database.ts src/lib/database-kv-backup.ts

# 2. Replace with Prisma version
cp src/lib/database-prisma.ts src/lib/database.ts

# 3. Generate Prisma Client
npm run db:generate

# 4. Create database
npm run db:push

What's Changed

• Storage Backend: spark.kv → Prisma ORM
• Data Persistence: Key-value store → Relational database (SQLite/PostgreSQL/MySQL)
• Type Safety: Runtime types → Compile-time types with Prisma
• API: No changes - Same Database class methods

Features

✅ Full type safety with TypeScript ✅ Relational data with foreign keys ✅ Connection pooling and optimization ✅ Easy to scale (SQLite → PostgreSQL) ✅ Migration tracking ✅ Same API - no code changes needed

Database Models

The schema includes:

• User, Credential
• Workflow, LuaScript, PageConfig, ModelSchema
• AppConfiguration, Comment
• ComponentNode, ComponentConfig
• CssCategory, DropdownConfig
• InstalledPackage, PackageData
• Tenant, PowerTransferRequest
• SystemConfig, SMTPConfig, PasswordResetToken

Verification

After migration, verify the setup:

# Check Prisma Client is generated
ls node_modules/@prisma/client

# Check database file exists (SQLite)
ls dev.db

# Start dev server
npm run dev

Rollback

If issues occur:

# Restore old database.ts
cp src/lib/database-kv-backup.ts src/lib/database.ts

The system will fall back to spark.kv storage.
