How to pass `stream.file` to another server as `multipart/form-data`?

Hi there!

I’ve started to use apollo-upload-server and faced with an issue. What I want to achieve is to pass (proxy) stream.file to another server as a file (multipart/form-data). Any ideas how I can do that without saving files.stream to the file and then streaming that file to another server?

This is my current workaround/hack

...
    const tmpFilePath = `${this.config.tmpDirPath}/${uuidv4()}`;
    await new Promise((resolve, reject) => {
      const handlerError = (error) => {
        fs.unlinkSync(tmpFilePath);
        reject(error);
      };
      file.stream
        .on('error', handlerError)
        .pipe(fs.createWriteStream(tmpFilePath))
        .on('error', handlerError)
        .on('finish', resolve);
    });

    const response = await request.post({
      uri: `${this.config.nlpApiBase}/upload`,
      formData: {
        datasheet: fs.createReadStream(tmpFilePath),
      },
      json: true,
    });

    fs.unlink(
      tmpFilePath,
      err => err && console.log('Failed to delete temporary file', err),
    );

Yeah, I’m pretty sure that there is nothing wrong with apollo-upload-server. Just posted a question here as nobody responds to me there.

Thank you for the answers and your time. You have made a great tool, thank you for that.
