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`).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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). …

How to install
mdr add ericrisco/rsc-harness/nodejs@sha256:bd54a6bffa23f3f2The line at the top of this page pins the label git:20260729.baa11e7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
