TypeORM + PostgreSQL for Real NestJS APIs
Using TypeORM with PostgreSQL is common in NestJS projects, but using it badly can create serious production problems. Slow queries, missing indexes, broken migrations, bad transactions, and N+1 queries can damage your backend performance.
In this video, we explain how TypeORM and PostgreSQL should be used in a real NestJS backend. We cover repositories, migrations, soft delete, optimistic concurrency, transactions, and database discipline.
This is Part 4 of the NestJS backend architecture series.
Topics covered:
TypeORM with NestJS
PostgreSQL for backend APIs
Database migrations
Repository contracts
