My crusty Python code implementing EPUB, with the conforming uncompressed mimetype file as first member in the archive:

Robin Sloan has a good Ruby project that builds good-looking web pages alongside EPUB files: https://github.com/robinsloan/perfect-edition

It was in porting that to Racket [1] that I learned about some of these EPUB standard details.

But spoiler alert, both projects just shell out to `zip` to do the actual compression.
