Individual skill
nodejs
Use when building or operating a plain Node.js / Express 5 backend service: project layout, async correctness, central error middleware, fail-fast config, graceful shutdown on SIGTERM. NOT DI modules/providers/guards (that is `nestjs`), NOT the type system or tsconfig (that is `typescript`), NOT REST contract design (that is `api-design`).

# Node.js backend services
Stand up a plain Node.js HTTP/JSON service — `node:http` or Express 5 — that a person can read, test, and operate without a DI framework. This skill is about the runtime and the request lifecycle: how to lay out the code, how to keep async correct, how errors become status codes, how config fails fast, and how the process dies cleanly. The contract shape, the type system, and the data layer live elsewhere (see the boundary below).
## Boundary
- The app is built around `@Module` / `@Injectable` / DI providers, guards, interceptors, pipes, exception filters → [`nestjs`](../nestjs/SKILL.md). Nest starts the moment the DI container appears; route away then, do not half-build it here.
- Pure TypeScript type system, generics, `tsconfig` → [`typescript`](../typescript/SKILL.md). This skill uses TS but does not teach types.
- REST resource modeling, versioning, pagination, status-code semantics (framework-agnostic) → [`api-design`](../api-design/SKILL.md). This skill *wires* the handlers; api-design decides the contract. Cross-cutting error taxonomy → [`error-handling`](../error-handling/SKILL.md).
- Schema, queries, connection pool, migrations → [`postgresdb`](../postgresdb/SKILL.md) / [`prisma-orm`](../prisma-orm/SKILL.md) / [`drizzle-orm`](../drizzle-orm/SKILL.md). *Calling* a repository stays here; designing the table does not.
- Containerizing / shipping → [`docker`](../docker/SKILL.md) / [`deployment`](../deployment/SKILL.md). Choosing the logging/metrics/tracing stack → [`observability`](../observability/SKILL.md). This skill emits structured logs and a shutdown hook; it does not own the pipeline.
