Forward Multipartform Request From One GraphQL API To Other GraphQL API

I'm uploading files from the browser via a multipart request to a GraphQL-API which is powered by graphql-yoga which is powered by express. Now I want to forward this exact same re

Solution 1:

I found a solution here and adapted the function to get the raw body. Now the file contents are not shifted anymore on the target host.

const concatStream = require('concat-stream');
function getRawBody(req, res, next) {
  req.getRawBody = new Promise(resolve => {
    req.pipe(concatStream(function (data) {
      resolve(data);
    }));
  });
  next();
}
