nodejs-backend SKILL.md skillA
nodejs-backend from iliaal/whetstone is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add iliaal/whetstone/nodejs-backend@git:20260227.215f429Pins git:20260227.215f429 in mdr.lock. Pin the fingerprint instead.

Node.js backend patterns: framework selection, layered architecture, TypeScript, validation, error handling, security, production deployment. Use when building REST APIs, Express/Fastify servers, microservices, 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
## Framework Selection
| Context | Choose | Why |
|---------|--------|-----|
| Edge/Serverless | Hono | Zero-dep, fastest cold starts |
| Performance API | Fastify | 2-3x faster than Express, built-in schema validation |
| Enterprise/team | NestJS | DI, decorators, structured conventions |
| Legacy/ecosystem | Express | Most middleware, widest adoption |
Ask user: deployment target, cold start needs, team experience, existing codebase.
## 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)
├── config/ # Env, DB pool, constants
└── types/ # Shared TypeScript interfaces
```
- Routes never contain business logic
- Services never import Request/Response
- Repositories never throw HTTP errors
- For scripts/prototypes: single file is fine — ask "will this grow?"
## TypeScript Rules
- Use `import type { }` for type-only imports — eliminates runtime overhead

How to install
mdr add iliaal/whetstone/nodejs-backend@sha256:899fb1fec22cdb23The line at the top of this page pins the label git:20260227.215f429, 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.
