TypeORM

TypeORM is a high-performance ORM for TypeScript and JavaScript (ES5+) that runs on Node.js, browsers, and mobile devices.

This toolkit bridges the gap between TypeScript classes and relational databases: PostgreSQL, MySQL, and MariaDB included. It supports both Data Mapper and Active Record patterns for architectural flexibility. Developers manage complex migrations and relations (One-to-One, Many-to-Many) through decorators like @Entity and @Column. It integrates natively with NestJS and provides a robust CLI for schema synchronization and seed data management.
