  data_url = "data:image/jpeg;base64,[Base64 encoded image goes here]";
 
// Save the image synchronously.
ba64.writeImageSync("myimage", data_url); // Saves myimage.jpeg.
 
// Or save the image asynchronously.
ba64.writeImage("myimage", data_url, function(err){
  if (err) throw err;
 
  console.log("Image saved successfully");
 
  // do stuff
});
