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
