NestJS best practices and architecture patterns for production apps.

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

Comprehensive best practices guide for NestJS applications. Contains 40 rules across 10 categories, prioritized by impact to guide automated refactoring and code generation.

## When to Apply

Reference these guidelines when:

- Writing new NestJS modules, controllers, or services
- Implementing authentication and authorization
- Reviewing code for architecture and security issues
- Refactoring existing NestJS codebases
- Optimizing performance or database queries
- Building microservices architectures

## Rule Categories by Priority

| Priority | Category | Impact | Prefix |
|----------|----------|--------|--------|
| 1 | Architecture | CRITICAL | `arch-` |
| 2 | Dependency Injection | CRITICAL | `di-` |
| 3 | Error Handling | HIGH | `error-` |
| 4 | Security | HIGH | `security-` |
| 5 | Performance | HIGH | `perf-` |
| 6 | Testing | MEDIUM-HIGH | `test-` |
| 7 | Database & ORM | MEDIUM-HIGH | `db-` |
| 8 | API Design | MEDIUM | `api-` |
| 9 | Microservices | MEDIUM | `micro-` |
| 10 | DevOps & Deployment | LOW-MEDIUM | `devops-` |

How to install

The exact contents, by fingerprint

mdr add higoralves/orc/nestjs-best-practices@sha256:1afcad9081d35c88

The line at the top of this page pins the label v1.1.0, 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.
