How to make a file server in Node.js?

Question

JavaScript

There is a code:

const http = require("http");
 
http.createServer(function(request, response){
     
    response.setHeader("UserId", 12);
    response.setHeader("Content-Type", "text/html; charset=utf-8;");
    response.write("<input type="file">
<section>
<option>Не выбрано</option>
</section>");
    response.end();
}).listen(8000);

How to make the selected file in the input appear in the section list and when you click on it, it will be downloaded.
