NestJS backend framework - modules, controllers, services, DI, guards, pipes, interceptors, exception filters, middleware, DTOs with class-validator
npx skills add majiayu000/claude-skill-registry --skill api-framework-nestjs --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# NestJS Patterns > **Quick Guide:** NestJS is an opinionated, modular Node.js framework built on TypeScript. Use modules to organize features, controllers for HTTP routing, services for business logic with dependency injection, DTOs with class-validator for validation, guards for auth, and exception filters for error handling. Key gotchas: always register services in module `providers`, always enable `ValidationPipe` globally with `whitelist: true`, never put business logic in controllers, never instantiate services with `new`. NestJS 11 is the current stable version (SWC default compiler, Express v5, reversed termination hooks). --- <critical_requirements> ## CRITICAL: Before Using This Skill > **All code must follow project conventions in CLAUDE.md** (kebab-case, named exports, import ordering, `import type`, named constants) **(You MUST use `@Injectable()` on every service and register it in the module `providers` array)** **(You MUST enable `ValidationPipe` globally with `whitelist: true` and `forbidNonWhitelisted: true`)** **(You MUST use DTOs with class-validator decorators for ALL request body validation — never validate manually in controllers)** **(You MUST throw NestJS b

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill api-framework-nestjs --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
