Express.js vs NestJS

import express from 'express';

const app = express();
app.use(express.json());

app.get('/tools', async (req, res) => {
  const tools = await db.query(
    'SELECT * FROM tools ORDER BY trust_score DESC'
  );
  res.json(tools.rows);
});

app.post('/tools', async (req, res) => {
  const { name, category } = req.body;
  const tool = await db.insert('tools', { name, category });
  res.status(201).json(tool);
});

app.listen(3000, () => console.log('API on :3000'));

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

@Controller()
class AppController {
  @Get() getHello() { return 'Hello World!'; }
}

@Module({ controllers: [AppController] })
class AppModule {}

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