Which ORMs are supported by this skill?

This skill provides specific syntax, patterns, and best practices for major Node.js ORMs including Sequelize, TypeORM, and Prisma.

How does it handle zero-downtime migrations?

It utilizes multi-phase strategies such as adding backward-compatible columns, backfilling data, and code-switching to ensure service remains uninterrupted during schema changes.

Can it assist with data transformation between different databases?

Yes, it includes patterns for complex data transformations, such as splitting combined strings into distinct columns or handling dialect differences between PostgreSQL and MySQL.

What is the recommended approach for failed migrations?

The skill emphasizes transaction-based migrations and mandatory rollback (down) methods to ensure the database can be safely reverted to its previous state if an error occurs.

Database Management

Executes complex database schema and data migrations across multiple ORMs with robust rollback and zero-downtime strategies.

About

This skill empowers Claude to architect and execute sophisticated database migrations using popular ORMs like Sequelize, TypeORM, and Prisma. It provides structured guidance on schema transformations, complex data reformatting, and cross-platform transitions while prioritizing system stability through transaction-based rollbacks and zero-downtime deployment patterns. It is an essential tool for developers refactoring data models, upgrading database versions, or migrating between different database technologies without risking data integrity or service availability.
