NestJS best practices and architecture patterns for building production-ready applications. This skill should be used when writing, reviewing, or refactoring NestJS code to ensure proper patterns for modules, dependency injection, security, and performance.
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
# NestJS Best Practices <!-- CORE-OVERLAY-START --> ## This repository (Asymmetric-al/core) These repo-owned sections are intentionally kept on top of the vendored NestJS skill. If upstream refreshes replace this file, reconcile this overlay before running `bun run skills:sync`. Core is a Bun + Next.js monorepo, not a NestJS application. Do not introduce NestJS modules, controllers, TypeORM, or a Nest runtime into this repository. ### Triggers - Reviewing NestJS patterns in third-party or vendored NestJS code. - Explicit NestJS architecture, DI, or security questions. ### Workflow 1. Confirm the files under edit are actually NestJS, not Core Next.js / `packages/api`. 2. Prefer `docs/ai/rules/backend.md` and the data-access boundary for product work. 3. Use this skill only as NestJS reference; do not restyle Core around NestJS examples. ### Checklist - [ ] Confirmed the task is NestJS reference, not a Core stack change. - [ ] Did not add NestJS, TypeORM, or Nest modules to this monorepo. - [ ] Kept tenant, auth, and data-access rules authoritative for product code. <!-- CORE-OVERLAY-END --> …

How to install
mdr add asymmetric-al/core/nestjs-best-practices@sha256:9332ca9be96403beThe line at the top of this page pins the label v1.2.0, 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.
