Then you can use it in your extensions. ### How to use? Plugin for Joomla developers. It allows you to use [PDF.js](https://mozilla.github.io/pdf.js/getting_started) anywhere in Joomla 4+: in modules, components, plugins. To do this in your code, use ``` getDocument()->getWebAssetManager(); $wa->useScript('wt-pdf-js'); // Local file $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`: ``` AddType text/javascript mjs ``` ## Joomla **Extension type:** Plugin **Folder:** System **Joomla version:** 5.2.3, 5.3.3 ## What's new 2025-09-16 17:25:46 Addition ### v.5.4.149 Update library to v.5.4.149 --- ## Related extensions [WT View PDF](https://web-tolk.ru/en/dev/joomla-plugins/wt-view-pdf-joomla-plugin) ## JSON-LD Schema ```json { "@context": "https://schema.org", "@type": "BreadcrumbList", "@id": "https://web-tolk.ru/#/schema/BreadcrumbList/17", "itemListElement": [ { "@type": "ListItem", "position": 1, "item": { "@id": "https://web-tolk.ru/en", "name": "Home" } }, { "@type": "ListItem", "position": 2, "item": { "@id": "https://web-tolk.ru/en/dev", "name": "Joomla extensions" } }, { "@type": "ListItem", "position": 3, "item": { "@id": "/en/dev/joomla-plugins", "name": "Joomla plugins" } }, { "@type": "ListItem", "position": 4, "item": { "name": "WT PDF.js" } } ] } ``` ```json { "@context": "https://schema.org", "@graph": [ { "@type": "Organization", "@id": "https://web-tolk.ru/#/schema/Organization/base", "name": "WebTolk", "url": "https://web-tolk.ru/", "logo": { "@type": "ImageObject", "@id": "https://web-tolk.ru/#/schema/ImageObject/logo", "url": "images/webtolk-1080p.jpg", "contentUrl": "images/webtolk-1080p.jpg", "width": 1920, "height": 1080 }, "image": { "@id": "https://web-tolk.ru/#/schema/ImageObject/logo" }, "sameAs": [ "https://github.com/WebTolk", "https://github.com/sergeytolkachyov", "https://vk.com/web_tolk", "https://vk.com/webtolkru", "https://tenchat.ru/sergeytolkachyov", "https://t.me/sergeytolkachyov", "https://t.me/webtolkru" ] }, { "@type": "WebSite", "@id": "https://web-tolk.ru/#/schema/WebSite/base", "url": "https://web-tolk.ru/", "name": "WebTolk websites development, Joomla Extensions", "publisher": { "@id": "https://web-tolk.ru/#/schema/Organization/base" } }, { "@type": "WebPage", "@id": "https://web-tolk.ru/#/schema/WebPage/base", "url": "https://web-tolk.ru/en/dev/joomla-plugins/wt-pdf-js", "name": "WT PDF.js - WebTolk websites development, Joomla Extensions", "description": "A general-purpose, web standards-based platform for parsing and rendering PDFs.", "isPartOf": { "@id": "https://web-tolk.ru/#/schema/WebSite/base" }, "about": { "@id": "https://web-tolk.ru/#/schema/SoftwareApplication/base" }, "inLanguage": "en-GB", "breadcrumb": { "@id": "https://web-tolk.ru/#/schema/BreadcrumbList/17" } }, { "@type": "SoftwareApplication", "name": "WT PDF.js", "url": "https://web-tolk.ru/en/dev/joomla-plugins/wt-pdf-js", "description": "A general-purpose, web standards-based platform for parsing and rendering PDFs.", "applicationCategory": "Joomla plugins", "softwareVersion": "5.4.149", "downloadUrl": "https://web-tolk.ru/en/get?element=wtpdfjs", "image": "https://web-tolk.ru/images/swjprojects/projects/98/en-GB/icon.webp", "operatingSystem": "ANY", "interactionStatistic": [ { "@type": "InteractionCounter", "interactionType": "https://schema.org/DownloadAction", "userInteractionCount": 2326 }, { "@type": "InteractionCounter", "interactionType": "https://schema.org/ViewAction", "userInteractionCount": 2147 } ], "mainEntityOfPage": { "@type": "WebPage", "url": "https://web-tolk.ru/en/dev/joomla-plugins/wt-pdf-js" }, "softwareRequirements": "Joomla", "applicationSubCategory": "Joomla plugins, Web Assets", "isAccessibleForFree": true } ] } ```
