const PORT = process.env.PORT || 3000;

const fileName = path.parse(filePath).base;
const fileSize = fs.statSync(filePath).size;

const mimeType = mime.lookup(filePath);

const server = http.createServer((req, res) => {
  res.setHeader("Content-Disposition", "attachment;filename=" + fileName);
  res.setHeader("Content-Type", mimeType);
  res.setHeader("Content-Length", fileSize);

  stream.pipeline(fs.createReadStream(filePath), res, (err) => {
    if (err) console.error(err);
  });
});

server.listen(PORT, () => console.log('Listening to port', PORT));
