full code here
(is this approach good ) :

handle.use(auth).post((req, res) => {
  const s3 = new AWS.S3({
    endpoint: new AWS.Endpoint('fra1.digitaloceanspaces.com'),
    accessKeyId: process.env.SPACES_KEY,
    secretAccessKey: process.env.SPACES_SECRET,
    region: 'fra1',
    // sslEnabled: true,
  });
  function paths({ id, ct }) {
    console.log('id', id, ct);
    switch (ct) {
      case 'tck':
        return `nor-platforms/${id}/tickets`;
      case 'prd':
        return `nor-platforms/${id}/products`;
      case 'pcs':
        return `nor-platforms/${id}`;
      default:
        return false;
    }
  }
  try {
    const form = new formidable.IncomingForm({ multiples: true, maxFileSize: 50 * 1024 * 1024 });
    form.parse(req, async function (err, fields, files) {
      console.log('files', files, 'fields', fields);
      const { file } = files;
      const body = file.length > 0 ? file.map((itm) => fs.readFileSync(itm.filepath)) : fs.readFileSync(file.filepath);
      const contentType = file.length > 0 ? file.map((itm) => itm.mimetype) : file.mimetype;
      const key = file.length > 0 ? file.map((itm) => itm.originalFilename) : file.originalFilename;
      // const data = await saveFile(files.file, req.user._id);
      console.log('body', body, 'key', key, 'contenttype', contentType);
      // res.status(200).json({ files: data });
      console.log('se', s3);
      await s3
        .upload({
          Bucket: paths({ id: req.user._id, ct: fields?.ct }),
          ACL: 'public-read',
          Key: key,
          Body: body,
          ContentType: contentType,
        })
        .send((err, data) => {
          if (err) {
            return res.status(500).json('Internal Error Please try again');
          }
          if (data) {
            console.log('data', data);
            return res.status(200).json({ files: data.Location });
          }
        });
    });
  } catch (err) {
    res.status(500).json('Internal Error Please try again');
  }
});
