Serve UI5 SDK with Node Express

Serve static UI5 SDK files with Node Express.
Two response headers are useful for static files. They are cach-control and cors.

const express = require('express');

// Constants

const PORT = 3000;

const HOST = '0.0.0.0';

// App

const app = express();

app.use ('/sdk', express.static (__dirname + "/sdk", {

    maxAge:'180d',

    etag:false,

    setHeaders: (res, path, stat) => {

        res.header('Access-Control-Allow-Origin', '*');

    }

}))

app.listen(PORT, HOST);

console.log(`Running on http://${HOST}:${PORT}`);
