Under the `build` folder add an app.js file with the following:

const express = require('express');
const app = express();
const port = 8000;

app.get('/', (req, res) => {
  console.log('getting request');
  res.sendFile('index.html', { root: __dirname });
});

app.use(express.static(__dirname + '/'));

app.use((req, res) => {
  res.redirect('/');
});

app.listen(port, () => {
  console.log(`app listening at http://localhost:${port}`);
});
