nestjs-coding-standard

To enforce consistent NestJS coding standards, apply rules for strict TypeScript usage, feature-based module organization, DTO validation with class-validator, and structured error handling. This ensures predictable structure and maintainable code.

The best way to organize NestJS modules for maintainability is using a feature-first structure with explicit imports and exports. This approach keeps related services, DTOs, and controllers grouped cohesively.

Implement DTO validation patterns in NestJS by using separate Create, Update, and Response DTOs with class-validator. Enable TypeScript strict mode to ensure type safety and robust payload validation.

Yes, this coding standard is specifically designed for NestJS 11.x services. It targets strict typing, feature-based modules, and structured logging to ensure compatibility and maintainability.

Handle errors and logging in NestJS by implementing custom exceptions and structured logging. This approach replaces generic error throwing with robust, traceable error management across your services.

Use separate Create and Update DTOs in NestJS to enforce strict validation rules tailored to each operation. This pattern prevents partial data corruption and maintains clear API contracts.
