Initialize a new NPM package and install express:

npm init              # then keep hitting enter
npm i --save express  # install express

create your express app in app.js:

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

app.get('/', function(req, res) {
  res.send('Hello Express')
})

// don't forget to export!
module.exports = app
