Which ORMs are supported by this skill?

This skill provides comprehensive patterns, code snippets, and best practices for Sequelize, TypeORM, and Prisma.

Can I use this skill to migrate between different database dialects?

Yes, it includes specific strategies for handling differences between database systems, such as converting JSONB types in PostgreSQL to JSON types in MySQL.

What happens if a migration fails during execution?

The skill emphasizes safety through transaction-based migrations and checkpoint-based rollbacks, ensuring that your database can be restored to its previous state if an error occurs.

How does this skill handle zero-downtime migrations?

It utilizes a multi-phase approach including backward-compatible schema changes, dual-writing data, backfilling, and final cleanup to ensure the application remains online throughout the process.
