How to store PDF.js document in local storage? How To use viewer.js with raw pdf source?

I have 2 questions revolving around displaying pdfs in a browser.

When I try to store a PDF.js document in local storage it does not work and crashes the javascript. Code below.

PDFJS.getDocument(array).then(function getPdfHelloWorld(_pdfDoc) {
    localStorage.setItem("pageNum", pageNum);
    localStorage.setItem("pdf-obj", JSON.stringify(_pdfDoc));
    pdfDoc = _pdfDoc;
    renderPage(pageNum);
  });

Any ideas?

Also since I may not be able to use paging this way I may need to look into using viewer.js for display and paging. I am wondering if there is a way to use viewer.js with raw pdf source rather than a file because that is all I have available to me. Thanks for any help.
