Simple Todo API — Nestjs Code

A minimal Todo REST API with in-memory storage.

import { Controller, Get, Post, Body } from '@nestjs/common';
import { Module } from '@nestjs/common';
import { NestFactory } from '@nestjs/core';

class TodoService {
	private todos: string[] = [];
	getAll() { return this.todos; }
	add(todo: string) { this.todos.push(todo); return todo; }
}

@Controller('todos')
class TodoController {
	constructor(private readonly service: TodoService) {}
	@Get() getTodos() { return this.service.getAll(); }
	@Post() addTodo(@Body('todo') todo: string) { return this.service.add(todo); }
}

@Module({ controllers: [TodoController], providers: [TodoService] })
class AppModule {}

async function bootstrap() {
	const app = await NestFactory.create(AppModule);
	await app.listen(3000);
}
bootstrap();

Nestjs Language Guide

NestJS is a progressive Node.js framework for building efficient, scalable, and maintainable server-side applications using TypeScript and modern JavaScript.

Primary Use Cases

▸Building RESTful APIs and GraphQL services
▸Creating microservices with built-in support
▸Developing server-side applications with TypeScript
▸Implementing real-time WebSocket applications
▸Building enterprise-grade backend systems

Notable Features

▸TypeScript-first design
▸Modular architecture
▸Dependency Injection container
▸Support for REST, GraphQL, WebSockets, and microservices
▸Built-in testing and CLI tools

Origin & Creator

NestJS was created by Kamil Myśliwiec in 2017 to provide a structured framework for building maintainable Node.js server-side applications with TypeScript.

Industrial Note

NestJS is popular in enterprise backend ecosystems and microservice architectures, providing scalable, modular, and maintainable server-side solutions.
