ok. with due respect i would not want to pay more for a DEVONthink license to help pay for the capital and support costs DEVON Technologies would bear to provide this. Especially since reading Epub books stored in DEVONthink can already be read with a reader of your choice. Just my two bits, as they say.
As to Koreader: they are extracting the text from m the PDF and then reformatting that. As long as there is a text layer, you could do that even in DT. But that has nothing to do with the PDF as such (imagine a carefully laid out text flowing around images, in two columns).
Well, that's at a very high level, and doesn't help us much. You can break down step 1 by reading up on the epub format itself (e.g.: wikipedia article and general info). Pretty quickly, you should notice that the format uses OCF to package together multiple files, so your first problem will be to create an OCF reader, which also means that you will need to be able to unzip the data in javascript (Florian Margaine's links should give you an idea of how others have solved this problem). At this point, I'd start looking for existing implementations in javascript, because you probably don't want to be implementing all of this from the ground up. This is all before we're even touching the actual contents of the epub file. Once you are past this point, you should be able to read in the actual contents, and attempt to translate them into HTML.
Regarding step 2, I'd start by looking at the various features provided by epub - text, CSS styling, embedded images, etc - and start attacking those one at a time, starting with whatever gives the most return for my time (probably text...).
TreineticEpubReader is a popular fork of readium-js-viewer it provides a very simple api to interact with epub files, you can load either the epub as .epub or serve the extracted folder path of the epub
All, I was looking for an epub reader with script capabilities to read my go books (the game not the language). None of the readers were displaying the diagrams nicely except, foliate and atril. However foliate does not have scripts, so no interactivity. Atril does, but cpu usage goes through the roof (on every distro I tried).
One of the things I really like about BibleWorks is their embedded EPub reader. Because I have purchased a lot of Christian Ebooks, I would love to be able to read the eBook within the workspace of Accordance. Being able to do simple searches would be great too.
I would be happy just to have an EPub reader in Accordance so I can read non-DRM ebooks. I'm looking at BibleWorks 10's epub reader as a sufficient comparable feature. I don't need full indexing and hyperlinks.
Stephen Wellum just came out with a new book on Christology. It's available as an EPub book on crossway.org. I would love to purchase it from Crossway, then read it in Accordance instead of my Ebook reader. That way, I can quickly dive deeper into Scripture when I want a closer look at various verses, passages, and Original texts.
John Piper has a lot of free books available to read. I don't expect Accordance to add it to their library, but having an ePub reader within the Accordance application on desktop just would be so nice.
Further we can have custom fonts, margins and dark mode to make it a really good reader along with syncing bookmarks/notes for the books between devices/systems. In my case it's the same storage but between Windows/Linux.
I like your suggestion and also looked at igorlogius' link. The problem I see is that such a reader would only work with files with no Digital Rights Management attached. While the universe of "open" Epub publications is by no means empty, virtually all the major publishers protect their publications in all reader formats. So, no browsing Barnes & Noble or Kindle, purchasing a book and immediately reading in your browser. I suspect the Mozilla Organization has little to no interest in breaking DRM protection or assisting anyone else in doing so. The homepage of Igorlogius' link states that it only reads non-DRM Epubs.
Baen books eschews DRM on any of its publications and also makes them available in other reader formats than Epub. Many to most self-published content is DRM free, as is anything in Gutenberg. There are several other organizations that are archiving materials on which the copyrights have expired; where the source material is suitable for conversion, "open" Epub is almost always available.
This ipad has IOS 5.1.1 and I can't find any compatible epub reader for it. I only bought it to be used exclusively used as an ereader because of the larger print and I expected ibooks to be on it already as part of the base build but I was wrong. PLEASE HELP !!
thanks for all this information Michel ... my only reason for wanting an ipad is to use it as an ereader so I don't really want all the other bells and whistles that come along with the much bigger price.
I read math textbooks. This requires constant shifting back and forward to specific places in the book via internal hyperlinks, bookmarks and (sub)chapter headings. The focus that I really need is navigability, and I'm surprised how little of it is implemented in epub readers. I usually read pdf, but I would like to read them as epub (or similarly reflowable format) and I have some books already as epub.
I know there are a lot of readers available and to so far I've tested Calibre (fails #7, barely #6), Icecream (fails #2) and Freda (fails #2, barely #4,#7) don't do all of the above. Kindle, Kobo and Vitalsource don't seem to do #8. Is there an epub reader that will do all of this?
I imagine a system where the reader application would allow you to read, highlight, and annotate sections of a book and save all of the relevant data (including links to the exact section) to a single text file per book.
I think this is a better idea than trying to force logseq into being an epub reader on top of being a note taking app. There are plenty of epub reader application developers we could reach out to if this is the direction the community decided to go.

I have signed up for Flightdeck and ran the EPUB file through that. It came up with some Validation errors. I have no idea how to fix them though and don't know if those errors would contribute to the reader problems
Thank you for your comment Bob. Yes, it does seem odd that a file created and exported with an Adobe program does not read well on an Adobe reading app. I'm afraid I'm a newbie with InDesign, although I'm familiar with other Adobe programs such as Photoshop, Premiere, Audition, Encore. Are the problems I'm experiencing with the epub in ADE mostly a result of ADE's shortcomings or are there things I should be doing prior to export that could alleviate the problems? Thanks again.

Accessibility is an essential benefit EPUBs offer to users: the format has the capacity to support many features that ensure all users will be able to enjoy the e-books. EPUBs are compatible with screen reader technology and they allow for alt text for images in the e-book. The table of contents in an EPUB can serve as a navigation aid and structured metadata helps with navigation as well as discoverability. The 2017 EPUB Accessibility specification from IPDF outlines requirements for EPUBs to conform to accessibility standards. While not all EPUBs conform to these specifications, many publishers and creators are designing their EPUB e-books with these provisions in mind.
It is a fact that there are other software specifically developed to read epub files. The advantage of having LibreOffice doing the same, would be to open a file as epub and save it in a different format such as pdf or even as a document, if it only contains characters.
If you only want to convert epub to pdf. Just use Calibre e-book manager, it does the job just fine.
If you need to import the epub to libreoffice to modify the contents, use calibre to convert epub to rtf format and then import within Libreoffice.
I know that is not the ideal solution, but it works.
Lilygo and M5 are the easiest options to start with since the hardware part is already solved. The benefit of M5 EPD is that it comes with an SD Card reader. Is possible also to upload the ePub books in the SPIFFs section of the ESP32 but there is limited space.
