Base64 is too large to open in a browser, any alternatives?

Question

My base64 PDF is too large that when I try and open it in a window, the url isn't pasted. I then substring'd it and the link would paste but of course.. it doesn't open as it hasn't received the whole base64.

Code:

   $.ajax({
    url: [database-url-here],
    type: 'GET',
    dataType: 'json',
    success: function(data){
      var pdf = (data.pdf).toString();

      window.open(pdf);
    }
  });

Answer 1

var w = window.open('', '', 'width=400,height=240'); // open blank page
w.document.write(
  '<embed type="application/pdf" ' +
         'width="400" height="240" ' +
         'src="data:application/pdf;base64,' + pdf + '">'
);

Answer 2

For too big base64 pdf files I convert it to blob and then create a new URL from that blob. Blob URL is much smaller then base64 url.

To convert I do something like this:

var url = 'data:application/pdf;base64,'+ base64string;
var blobUrl;
fetch(URL)
 .then(res => res.blob())
 .then(URL.createObjectURL)
 .then((ret) => {blobUrl=ret; return blobUrl;})
 .then(console.log)

One can test at this jsfiddle at example 2. Or see other alternatives here
