NestJS

NestJS is a structured, opinionated framework for Node.js, heavily inspired by Angular. NestJS 10 (2025) focuses on performance with SWC integration and refined standalone modules.

When to Use

• Enterprise Monorepos: Strict architecture (Controllers, Services, Modules) scales well.
• TypeScript First: Best-in-class TS support and decorators.
• Microservices: Built-in support for gRPC, MQTT, Redis transport layers.

Quick Start

// cats.controller.ts
@Controller("cats")
export class CatsController {
  constructor(private catsService: CatsService) {}
