Laden Sie mehrere Dateien Axios hoch hoch

// silly note but make sure you're constructing files for these (if you're recording audio or video yourself)
// if you send it something other than file it will fail silently with this set-up 
let arrayOfYourFiles=[image, audio, video]
// create formData object
const formData = new FormData();
arrayOfYourFiles.forEach(file=>{
  formData.append("arrayOfFilesName", file);
});

axios({
  method: "POST",
  url: serverUrl + "/multiplefiles",
  data: formData,
  headers: {
    "Content-Type": "multipart/form-data"
  }
})
//some error handling
