Nestjs Patterns

This is a solid reference for building production NestJS backends the right way. It covers the full stack: module organization, DTO validation with class-validator, guards and interceptors, environment config validation at boot, and keeping controllers thin while services own business logic. The structure guidance is opinionated but practical, pushing cross-cutting concerns into common folders and keeping DTOs close to their modules. You'll want this active when setting up new NestJS projects or refactoring messy ones, especially if you're tired of inconsistent error handling or controllers that do too much. The testing and transaction patterns alone save you from common pitfalls.
