dir2opds - serve books from a directory

dir2opds inspects the given folder and serves an OPDS 1.1 compliant server.

Overview

There are good options for serving books using OPDS. Calibre is a popular choice, but if you have a headless server, installing Calibre might not be the best option.

That's where calibre2opds comes in. However, if you have a large number of books and don't want to create a Calibre library, dir2opds can help you set up an OPDS server from a directory with one condition:

A folder should contain either only folders or only files.

Tested on

Moon+ reader

Cantook

It works on Cantook reader for me on iPhone.

It would be nice if this was stated in README.

KYBook 3

It works with KyBook 3 Ebook Reader if access to Local Network is enabled in settings.

To enable access go to Settings -> Apps -> KyBook 3 -> Local Network (checked).

It seems that KyBook is so old, that it does not trigger access prompt from iOS, so it has to be configured manually.
