title: How to send an array of files to express backend
body: <p>I am trying to send an array of images to my backend and then upload them with multer-s3. I am sending them through react to a node express backend. When I submit from the frontend it is a submitting an array of images like so: </p>
  
  <p>images : [ File(3195869) {name: "IMG - example.JPG", lastModified: 1514505624000, lastModifiedDate: Thu Dec 28 2017 17:00:24 GMT-0700 (MST), webkitRelativePath: "", size: 3195869, …}, ... ]</p>
  
  <p>But when I log req.body on the backend it returns [ {}, {}, {}, ... ] and req.files is undefined</p>
  
  <p>Why would the files not be making it through the post request??</p>
