mkdir app01
cd app01
npm init -y
npm install koa

app/index.js

const Koa = require('koa');
const app = new Koa();
 
app.use(async ctx => {
  ctx.body = 'Helló Világ';
});
 
app.listen(8000, () => {
  console.log('Server running on port 8000');
});

Futtatás:

node app

A külön routinghoz szükség van még egy függőségre:

npm install koa-router

app/index.js

const Koa = require('koa');
const app = new Koa();
const router = require('./routes/api');
 
app.use(router.routes());
 
app.listen(8000, () => {
  console.log('Server running on port 8000');
});

app/routes/api.js

const Router = require('koa-router');
 
const router = new Router();
 
router.get('/valami', async (ctx) => {
  ctx.body = 'Helló Világ';
});
 
module.exports = router
