FAQ

[Back to Top]

  1. I have installed hugo-embed-pdf in my website locally by cloning the repository and copying the files, but it does not work?
    A. hugo-embed-pdf uses pdf.js from mozilla. Pdf.js is now being served using a CDN.
    If you would like to use a local copy of PDf.js then you can make the following changes to the embed-pdf.html file.
  • Change the script tag at the top of the file from
<script src="https://cdn.jsdelivr.net/npm/[email protected]/build/pdf.min.js" integrity="sha256-UZQVSEoMbJ82/3uFjt4mYOTVVHIImtkp7u3L6LMH6/Y=" crossorigin="anonymous"></script>

to

<script type="text/javascript" src='{{"/js/pdf-js/build/pdf.js" | relURL}}'></script>
  • Change the path to the pdf.worker.js file at line number 124 from
pdfjsLib.GlobalWorkerOptions.workerSrc = 'https://cdn.jsdelivr.net/npm/[email protected]/build/pdf.worker.min.js';

to

pdfjsLib.GlobalWorkerOptions.workerSrc = "{{.Site.BaseURL}}" + 'js/pdf-js/build/pdf.worker.js';
