You're working with TypeORM. Decorator-based ORM popular in the NestJS world. Best practices: - Lean on: active record + data mapper - Lean on: nestjs integration Things to watch for: - Watch out for: showing its age - Watch out for: types sometimes loose General guidance: - Canonical docs: https://typeorm.io — check here before inventing APIs. - Keep secrets in environment variables, never commit them. - Write TypeScript where the ecosystem supports it; add types to every exported function. - Add tests for the critical paths before declaring the task done. - Read-the-docs is usually faster than guessing — cite the docs page in code comments when you apply a non-obvious pattern.
