Saving a Uint8Array to a binary file

by

These are utilities that I use to download files cross-browser. The nifty thing about this is that you can actually set the download property of a link to the name you want your filename to be.

FYI the mimeType for binary is application/octet-stream

var downloadBlob, downloadURL;

downloadBlob = function(data, fileName, mimeType) {
  var blob, url;
  blob = new Blob([data], {
    type: mimeType
  });
  url = window.URL.createObjectURL(blob);
  downloadURL(url, fileName);
  setTimeout(function() {
    return window.URL.revokeObjectURL(url);
  }, 1000);
};

downloadURL = function(data, fileName) {
  var a;
  a = document.createElement('a');
  a.href = data;
  a.download = fileName;
  document.body.appendChild(a);
  a.style="display: none";
  a.click();
  a.remove();
};

Usage:

downloadBlob(myBinaryBlob, 'some-file.bin', 'application/octet-stream');
