const formidable = require("formidable");
const fs = require("fs");
const http = require("http");

http.createServer((req, res) => {
  if (req.url == "/fileupload" && req.method.toLowerCase() === 'post') {
    const form = new formidable.IncomingForm();
    form.parse(req, (err, fields, files) => {
      if (err) {
        res.writeHead(400, { "Content-Type": "text/plain" });
        res.write("An error occurred during file upload");
        res.end();
        return;
      }
      const oldPath = files.filetoupload.filepath; // Use 'filepath' instead of 'path'
      const newPath = "/home/danish-butt/Documents/uploadedByNodeJs/" + files.filetoupload.originalFilename;
      fs.rename(oldPath, newPath, (err) => {
        if (err) {
          res.writeHead(500, { "Content-Type": "text/plain" });
          res.write("File upload failed");

        res.end();
      });
    });
  } else {
    fs.readFile("fileForm.html", (err, data) => {
      if (err) {
        res.writeHead(500, { "Content-Type": "text/plain" });
        res.write("Error loading form");
        res.end();
        return;
      }
      res.writeHead(200, { "Content-Type": "text/html" });
      res.write(data);
