How to use?

Plugin for Joomla developers. It allows you to use PDF.js anywhere in Joomla 4+: in modules, components, plugins.

To do this in your code, use

<?php

$wa->useScript('wt-pdf-js-remote'); // Use from CDN

Configuring MIME types on the server for *.MJS-files

Servers often do not have MIME types configured for files with *.mjs extensions. Therefore, the browser may not understand that this is actually javascript code and you may see an error in the browser console pdf.mjs:1 Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "application/octet-stream". Strict MIME type checking is enforced for module scripts per HTML spec. 

To solve this problem, you either need to ask the hosting company's technical support to configure MIME types for mjs files. Or do it yourself:

1. Make sure that the PHP module mod_mime is installed and enabled in the list of PHP extensions on the server.

2. Add the following code to the end of your .htaccess:

<IfModule mod_mime.c>
  AddType text/javascript mjs
</IfModule>
