One fun thing about Calibre is that the library is stored in a SQLite database. So, if you write a wrapper to parse that data, you don’t even need Calibre’s content server running!

I have the library stored on my NAS and am running a fairly simple Node.JS + Express + React web app on my Raspberry Pi that reads the database and provides web access this content.

Sadly, I don’t have the code in a publisher format as of yet.

One thing I’ve been meaning to do is add an upload feature so that I can have the web app add ebooks to the library. For now, I still have to fire up Calibre for that.

Edit: Wow, I just saw a post below for Calibre-Web. It’s the same thing I had been working on but it’s much much nicer than what I had hacked together!
