description	Generate SQL migration files from ORM schemas. Use when managing database changes.

Migration Generator

Your ORM schema changed and you need migration files. This tool reads your schema and generates timestamped UP and DOWN migrations.

One command. Zero config. Just works.

Quick Start

npx ai-migrate --orm prisma --name add_users

What It Does

• Reads Prisma, Drizzle, TypeORM, or Sequelize schemas
• Generates timestamped migration folders
• Creates both UP and DOWN SQL
• Includes proper guards (IF NOT EXISTS, etc.)

Usage Examples

# Prisma migration
npx ai-migrate --orm prisma --name add_users

# Drizzle with custom output
npx ai-migrate --orm drizzle --name add_orders --output ./db/migrations

# TypeORM
npx ai-migrate --orm typeorm --name add_products

Best Practices

• Test migrations locally - run up and down before deploying
• Keep them small - one logical change per migration
• Version control them - migrations are code
• Never edit deployed migrations - create new ones instead

When to Use This

• Schema changes need migration files
• Converting ORM operations to raw SQL
• Setting up migration workflow
• Learning proper migration structure
