Node.js backend patterns: layered architecture, TypeScript, validation, error handling, security, observability, logging, metrics, deployment. Use when building REST APIs, REST endpoints, middleware, Express/Fastify/Hono/NestJS/Koa servers, tRPC procedures, Bun servers, or server-side TypeScript.
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 **Verify before implementing**: For framework-specific APIs (Express 5, Fastify 5, Node.js 22+ built-ins), look up current, version-matched official docs before writing code. Prefer Context7 (`query-docs`) when available. Otherwise use available web tools to read the framework's official documentation, or the [Node.js API docs](https://nodejs.org/api/) for Node.js built-ins. Training data may lag current releases. ## Working rules - Validate request and third-party data before use; keep response serialization and error envelopes explicit. - Preserve caller-visible contracts and authorization when adding resilience or fallbacks. - Bound concurrency, set timeouts, and avoid blocking production request paths. - Verify actual resource identity before parsing or caching a reused client's result. - Exercise operational telemetry and failure paths, not successful return codes alone. ## Architecture ``` src/ ├── routes/ # HTTP: parse request, call service, format response ├── middleware/ # Auth, validation, rate limiting, logging ├── services/ # Business logic (no HTTP types) ├── repositories/ # Data access only (queries, ORM) …

How to install
mdr add iliaal/ai-skills/nodejs-backend@sha256:075015018240fec8The line at the top of this page pins the label git:20261011.09c16df, 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.
