Solid start. The page layout options could use a bit more work:

1. It initially defaults to showing two facing pages per screen, but the selector shows "Read a chapter as a long scrolled page" as selected. "Fit 2 page side by side in window" is the same and is presumably the actual default. Switching back to "long scrolled page" from that does do what you'd expect. This is fullscreen on a 1920x1080 desktop display.

2. I personally dislike side-by-side views - I find them distracting - but at this size the line length for "long scrolled page" is too long for readability. I'd prefer a "long scrolled page but with shorter lines and bigger margins" option, like Firefox's reader view.

Can you describe what motivated you to build an ebook reader for the browser, when multiple free desktop and mobile book readers exist?

Also, do I need to keep the screen open if I want to save my place in my book? It doesn't seem to save my book or my location when I reload the page.

Not the OP, but I find Calibre burdensomely heavy for what I want, and Okular far too glitchy. Also, sometimes I am at PCs where I can't install arbitrary software.

I think we still need far more/better solutions in the open source e-reading space.

I can't speak for the creator but I often read Japanese ebooks in my browser because it allows me to lookup unfamiliar words quickly with Yomichan and then create anki cards for them (if I want to).

A bit OOT but how do you transfer Yomichan to anki cards? Do you do it manually?

It's a built in feature using Ankiconnect.

I use Calibre daily, but for epub > dictionary > anki card there isn't a good workflow I've found.

> multiple free desktop and mobile book readers exist

Under many circumstances, some I've been in, none of those are an option, and a browser is all you've got.

>> when multiple free desktop and mobile book readers exist

Do you know a good list of available readers? I still searching for the one which fit for me. This one could be a good candidate after some polish.

hey, I actually was working on something similar ( forking from https://github.com/satorumurmur/bibi which is an open source epub reader ), but my objective was to allow

a) To save books in some place online like s3 or gdrive etc.

b) Allowing to use the "bookmark" feature across sessions.

My use case is that sometimes I am reading a EPUB and I have it in my tablet, but sometimes I have my computer, and othertimes I have my phone. Currently I have to download it 3 times to read it and remember the bookmark.

> To save books in some place online like s3 or gdrive etc

How far did you make it with this? S3 is tricky because they don't offer OAuth so the user basically has to generate an IAM user and access keys and paste them into your app. I'm currently exploring solutions to this problem.

Right, I only got to that, I entered my s3 keys manually. I think for a smoother experience I would use Google Drive, which provides OAuth access AFAIK.

Amazing! Great job! I'm so curious about your process

What programming language did you use?

What was the harder part?

Which format was the hardest?

How long did it take you?

ReadEra is an excellent piece of polished software that has everything I want in an e reader and is a joy to use. I would highly recommend using the free version, and then buying the premium to support the developer.

Great work! I join the margins bandwagon: when displaying a single column, it would be great to be able to have a not too big page width, as very long lines on a desktop monitor are hard to read.

Great work!

Maybe have to reconsider layout for big screens similar to mine. But browser resize is fine for now.
