Developers often encounter pitfalls when building NestJS applications, including misconfigured dependency injection scopes, circular dependencies, and ambiguous module organization that lead to brittle code and hard-to-maintain graphs.
Create a NestJS application and apply the recommended module and provider patterns to avoid common pitfalls.

Resolve NestJS circular dependencies by using forwardRef for mutual references and ensuring proper module wiring to prevent runtime crashes during dependency injection.
NestJS execution order follows middleware, then guards, then pipes, and finally exception filters, ensuring predictable request processing behavior and consistent error handling.
Configure NestJS validation pipes by enabling class-validator and class-transformer, then applying proper DTO usage with nested validation to ensure robust payload validation.
Organize NestJS modules by carefully managing provider placement, exporting providers correctly, and using global modules or forRoot/forRootAsync patterns to ensure proper availability across modules.
NestJS dependency injection fails when providers are not properly exported from their defining modules or imported incorrectly, leading to brittle code and unavailable dependencies across the module graph.
Use forwardRef in NestJS to break circular dependency cycles by allowing forward references during module wiring, which prevents runtime crashes when modules mutually depend on each other.
