Hi Simplifier Community,

how can I use a external library that requires a script type “module”. Like for example pdfjs@v4 is now using js modules.

<script src=”//mozilla.github.io/pdf.js/build/pdf.mjs” type=”module”></script>

Is there an argument for Simplifier´s addScript-method to set the script type?

Out of the box addScript is not using module. This means you get an error “unexpected token export”.

Maybe there is a solution to create a custom script tag with a preload script loaded with addScript. But I don’t have a enough knowledge how simplifier bundes his libraries to implement such a solution.

Best Regards

Christopher

Hi Christopher,
until we officially support static modules, you can also dynamically load modules via the official import() declaration. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import

For example when using import inside a Simplifier library:

import(“https://mozilla.github.io/pdf.js/build/pdf.mjs&#8221;).then((pdflib) => {
window.pdflib= pdflib;
});

You can of course use the import function directly inside a client side business object, without exposing the loaded library as a window property.

Kind regards
Steffen

Hi Steffen,

thank you for this great idea. I think that does the trick for me.

Here’s my final solution for the latest pdfJS libarary using modules:

const fullLibPath = ${SimplifierLoader.libraryRoot}/${sLibPath};
import(${fullLibPath}/pdf.min.mjs).then((pdfjsLib) => {
   window.pdfjsLib = pdfjsLib;
   window.pdfjsLib.GlobalWorkerOptions.workerSrc = ${fullLibPath}/pdf.worker.min.mjs;
});

I added the simplifier lib path to use the pdfjs lib uploaded to the simplifier server instead of the mozilla served lib.

Hi Christopher,

as far as I am aware, this currently not supported.
I think it would be a good idea to create a FR for this, as this could be very handy overall.

Kind regards
