// Source file: src/process_request.jsconst http = require("http");http    .createServer((req, res) => {        // For PUT/POST methods, wait until the        // complete request body has been read.        if (req.method === "POST" || req.method === "PUT") {            let body = "";            req.on("data", data => {                body += data;            });            req.on("end", () => processRequest(req, res, body));        } else {            return processRequest(req, res, "");        }    })    .listen(8080, "localhost");// continues...

The processRequest() function will be quite simple, limited to showing its parameters. This kind of code can become helpful if you need to better understand ...
