expressjsHow do I use Express.js or Nest.js for software development?

Express.js and Nest.js are two popular frameworks for building web applications and APIs. Express.js is a minimalistic web framework built on top of the Node.js platform, while Nest.js is a progressive Node.js framework for building efficient, reliable and scalable server-side applications.

Here is an example of a simple Express.js application:

const express = require('express');
const app = express();

app.get('/', (req, res) => {
  res.send('Hello World!');
});

app.listen(3000, () => console.log('Example app listening on port 3000!'));

Output example

Example app listening on port 3000!

This code will create an Express.js server that listens on port 3000 and responds to requests on the root route with a 'Hello World!' message.

Here is an example of a simple Nest.js application:

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  await app.listen(3000);
  console.log('Example app listening on port 3000!');
}
bootstrap();

Output example

Example app listening on port 3000!

This code will create a Nest.js server that listens on port 3000.

Both Express.js and Nest.js are powerful frameworks for developing web applications and APIs. For more information, see the following links:
