package.json

{
  "scripts": {
    "start": "nodemon app/index.mjs --watch app"
  }
}

index.mjs

import express from 'express';
 
const app = express();
const port = 8000;
 
app.get('/', (req, res) => {
  res.send('működik');
});
 
app.listen(port, () => {
  console.log(`Listening on port ${port}`);
});

Projekt létrehozása:

npm init -y

Függőségek telepítése:

npm install --save-dev @babel/core 
npm install --save-dev @babel/preset-env 
npm install --save-dev @babel/register
npm install --save-dev @babel/node

A Babel beállítása:

.babelrc

{
  "presets": [
    "@babel/preset-env"
  ]
}

app/index.js

import express from 'express';
 
const app = express();
const port = 8000;
 
app.get('/', (req, res) => {
  res.send('működik');
});
 
app.listen(port, () => {
  console.log(`Listening on port ${port}`);
});

node -r @babel/register app

Indítás nodemon alkalmazással:

package.json

{
  "name": "app01",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "nodemon --exec babel-node app --watch app"
  },
