How to generate blob from http response in java script?

Question

I am a beginner in javascript and web programming I am using node to create a pdf file and pipe it as an http response

On the client-side I am using angularjs to create blob from the response. Instead of getting a correct pdf file, i am getting a pdf page with a blank page. Did I created blob the wrong way? Is there something I missed?

I did try researching the internet, the closest thing I found is this: AngularJS: Display blob (.pdf) in an angular app

but it still does not work after i followed the instructions

my code:

  $http.get('pdf-page', null, { responseType: 'arraybuffer' }) .success(function (res) { console.log(res); var file = new Blob([data], {type: 'application/pdf'}); var fileURL = URL.createObjectURL(file); window.open(fileURL); }); 

result of console.log(res):

%PDF-1.3 % 5 0 obj << /Type /Page /Parent 1 0 R /MediaBox [0 0 612 792] /Contents 3 0 R /Resources 4 0 R

endobj 4 0 obj << /ProcSet [/PDF /Text /ImageB /ImageC /ImageI] /Font << /F1 6 0 R

endobj 7 0 obj << /Producer ( PDFKit) /Creator ( PDFKit) /CreationDate (D:20150121171417Z) endobj 6 0 obj << /Type /Font /BaseFont /Helvetica /Subtype /Type1 /Encoding /WinAnsiEncoding endobj 2 0 obj << /Type /Catalog /Pages 1 0 R endobj 1 0 obj << /Type /Pages /Count 1 /Kids [5 0 R] endobj 3 0 obj << /Length 110 /Filter /FlateDecode stream x e A QC =E/ `p! ^ o ^ $$ F % _w+q3 l 6 & ! h8 a e ș . 0 08vrpd H6 k ֯Zo < endstream endobj xref 0 8 0000000000 65535 f 0000000462 00000 n 0000000413 00000 n 0000000519 00000 n 0000000119 00000 n 0000000015 00000 n 0000000316 00000 n 0000000208 00000 n trailer << /Size 7 /Root 2 0 R /Info 7 0 R startxref 701 %%EOF
