fileWriteStreamHandler: S3 access req data and other form values

[leopucci]

Hi, About store-files-on-s3.js in the example folder, How can I access req inside uploadStream Why? to get the bucket name on req. To get the path/key to destination. How can I access req info or send more data to uploadStream function? Thanks

const uploadStream = (file) => {
  const pass = new PassThrough();
  s3Client.upload(
    {
      Bucket: 'demo-bucket',
      Key: file.newFilename,
      Body: pass,
    },
    (err, data) => {
      console.log(err, data);
    },
  );

  return pass;
};

const server = http.createServer((req, res) => {
  if (req.url === '/api/upload' && req.method.toLowerCase() === 'post') {
    // parse a file upload
    const form = formidable({
      fileWriteStreamHandler: uploadStream,
    });

    form.parse(req, () => {
      res.writeHead(200);
      res.end();
    });

    return;
  }

Use a closure or the .bind method.

const uploadStream = (req, file) => {
  // req available
  const pass = new PassThrough();
  s3Client.upload(
    {
      Bucket: 'demo-bucket',
      Key: file.newFilename,
      Body: pass,
    },
    (err, data) => {
      console.log(err, data);
    },
  );

  return pass;
};

const server = http.createServer((req, res) => {
  if (req.url === '/api/upload' && req.method.toLowerCase() === 'post') {
    // parse a file upload
    const form = formidable({
      fileWriteStreamHandler: uploadStream.bind(undefined, req),
    });

    form.parse(req, () => {
      res.writeHead(200);
      res.end();
    });

    return;
  }
