Remote resource reference

Daniele Giampà · 01-30-2024, 07:00 AM

Hello

I created a generative poem on my web page and I converted it into an EPUB3 document.
I used GSAP to create two animations and in the EPUB Check I get the following error:

Remote resource reference is not allowed in this context; resource "https://cdnjs.cloudflare.com/ajax/libs/gsap/3.9.1/gsap.min.js" must be located in the EPUB container.

What does this mean?

I work with Oxygen XML and Sigil.

I am looking forward to your feedback.

Daniele

The gasp.min.js file that's referenced in your ePub is not part of your epub, it's on a cloudflare server. This is usually fine for a web page, but not for an ePub, where all required resources must be part of the ePub. You'll need to get a copy of the file and include it in the ePub and then make sure references to it are to the ePub copy, not the copy on cloudflare. You should probably check that you're allowed to do that under whatever licence covers the gsap code.

Whether the javascript animations will work in an ePub is not something I know. It certainly won't work in all ePub readers.

Thank you for the quick reply.

I found the GASP files and created two new code files.
Can I insert them in the folder OEBPS/Misc with all my other JavaScript files?

The licence is not a problem because I won't sell my EPUB.

Since other .js files are already there, that seems the right place. Then you'll need to find and update the references to them in your (X)HTML.

And you're right - for personal projects the gsap libraries are free. But you should sign up with them for their free licence. Free doesn't mean you may use it without permission. https://gsap.com/pricing/

But if you ever do want to sell the epub you'll need to buy a licence.

I edited the files. In the CSS file, I deactivated the display function of the verses, and now all the verses are visible;

.verse {
/* display: none; */
z-index: 3;
}

In the JavaScript file, I replaced the existing code with a new code and nothing happened; the JS doesn't connect with the XHTML file;

The current version of the EPUB can be downloaded from the following page: https://www.edgedpub.com/sample_work_6.php

I also created a pen with the same files https://codepen.io/edgedpub/pen/BabrNzz

The JavaScript animation works now!

In the XHTML file, I moved the JS link from the <head> to the last line of the <body>.
