Lesson 1 / 33

Why NestJS?

Enterprise-grade architecture with TypeScript and decorators out of the box.

Express meets architecture

NestJS layers powerful abstractions (modules, dependency injection, decorators) on top of Express (or Fastify), giving you enterprise patterns without the framework overhead.

TypeScript first

Built for TypeScript. Decorators, strong types, and compile-time checks catch bugs before they ship.

Batteries included

CLI for scaffolding, testing utilities, ORM integration, authentication, validation, logging—everything you need for production apps.
