NestJS interview questions, quiz and handbook in your Learning Dashboard
What you will learn
- Modules group controllers and providers into features.
- Dependency injection makes services easy to swap and test.
- Guards, pipes and interceptors form a clear request pipeline.
Structure for big teams
Express leaves architecture to you, and large codebases drift into inconsistency. NestJS provides the structure up front: modules, controllers, providers and a dependency injection container, inspired by Angular.
New developers find code where they expect it, and cross-cutting concerns like auth and validation live in one place.
