NestJS TypeORM Integration

Acerca de

This skill provides specialized guidance for connecting NestJS applications to databases using TypeORM. It streamlines the entire integration process—from initial configuration and environment-driven settings to complex entity relationship design and transactional logic. By following production-ready standards like migration-driven schema updates and dependency-injected repositories, it ensures database layers are robust, maintainable, and optimized for performance within the NestJS ecosystem.
