nestjs-best-practices

NestJS best practices for module design and dependency injection involve applying structured rules and concrete before-and-after examples to reduce architectural drift and code smell. This guides you in structuring modules and DI correctly during development and refactoring.

To refactor a NestJS codebase and fix architectural drift, use a centralized collection of rules covering architecture, error handling, and security. Apply the provided before and after guides during code reviews to align your modules with production-grade patterns.

Yes, these NestJS rules target codebases ranging from small modules to large microservices. The practices are applicable during module design, code reviews, and refactoring to ensure consistent architecture, performance, and security across varying project scales.

Handling security and testing in a NestJS application involves applying comprehensive rules and examples that cover both areas. These practices guide you in writing secure code and robust tests by reducing code smell and aligning with production-grade patterns.

The best way to automate NestJS code validation is to leverage a lightweight, automation-friendly structure that feeds agents and tooling. This structure provides actionable rules and examples to automatically generate or validate code against best practices.
