Review & Verify NestJS
How generated code fails in this language, and the checks that catch it before your users do.
Know the failure modes
01
The NestJS mistakes language models actually make
TypeScript catches the type errors. What gets through is authorisation, validation configuration, and logic drifting out of services — and those are the ones that matter.
02
Dependency hygiene for NestJS projects
npm's problems, plus a framework whose packages must all be on the same major version, plus a decorator ecosystem where a version mismatch produces a runtime error with no useful message.
03
Security review checklist for NestJS applications
The framework gives you the right places to put security controls. What it will not do is tell you when one is missing — and a missing global is invisible until someone finds it.
04
The performance traps in generated NestJS code
Two Nest-specific problems dominate: N+1 queries through the ORM, and request-scoped providers that quietly make your entire dependency graph rebuild on every request.
