файлы api ???

В нашем случае образы серверов статического и динамического контента не отличаются. 
Что касается самого сервера, то код его следующий:

"use strict";

const express = require('express');
const bodyParser = require('body-parser');
const http = require('http');

const app = express();
const server = http.Server(app);

const path = require('path');

const AppRouter = require('./Routers/App.router');

app.use('/api'.concat('/demo'), AppRouter);

server.listen(8080);
Простой маршрутизатор (Router), может выглядеть следующим образом:

const express = require('express');
const router = express.Router();

router.get('/demo', function (req, res, next) {
  res.status(200).json({
    success: true,
    process: 'started',
  });
})

module.exports = router;
