NestJS#

NestJS is a progressive Node.js framework for building efficient, reliable, and scalable server-side applications.

Features

  • Architecture: Based on TypeScript and heavily inspired by Angular.

  • Extensibility: Easily integrates with other libraries.

  • Modularity: Encourages modular development with decorators.

  • Support for GraphQL: Built-in support for GraphQL and WebSockets.

Use Cases

  • Enterprise applications requiring robust structure.

  • Applications needing extensive scalability and testability.

Getting Started

To install NestJS and start a new project, run:

npm install -g @nestjs/cli nest new project-name

Basic Server Example

Create a controller (e.g. src/app.controller.ts) in your src folder to handle HTTP requests.

import { Controller, Get } from '@nestjs/common'; @Controller() export class AppController {  @Get()  getHello(): string {  return 'Hello from NestJS!';  } }

Then update the main module (src/app.module.ts) to include this controller.

import { Module } from '@nestjs/common'; import { AppController } from './app.controller'; @Module({  imports: [],  controllers: [AppController],  providers: [], }) export class AppModule {}

Finally, start the server.

npm run start

Now, visit http://localhost:3000 to see the message “Hello from NestJS!”
