Why NestJS?
Learn why NestJS adds modules, dependency injection and decorators on top of Express or Fastify for TypeScript back ends.
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.
