Let's talk Uploads

XHR Uploads

<script>
  function upload(blobOrFile) {
    var xhr = new XMLHttpRequest();
    xhr.open('POST', '/server', true);
    xhr.onload = function(e) { ... };

    // Listen to the upload progress.
    var progressBar = document.querySelector('progress');
    xhr.upload.onprogress = function(e) {
      if (e.lengthComputable) {
        progressBar.value = (e.loaded / e.total) * 100;
        progressBar.textContent = progressBar.value; // Fallback for unsupported browsers.
      }
    };

    xhr.send(blobOrFile);
  }

</script>
