Here's the full context: https://github.com/greg-hellings/jsword-json

It's a simple read-only REST resource/WebSocket server that fetches back a
list of installed modules, a list of the top-level keys in that module, and
any parse-able key's worth of data in JSON. It's super simple and is only
intended to be a proof of concept that hitting a Sword module to fetch out
JSON is not very difficult. You can sample it running at
http://thehellings.com:10001/ or over WebSockets at ws://
thehellings.com:10002/, though please be gentle. I've included a
rudimentary amount of app-side caching to improve performance of some of
the longer-running requests (e.g. "Please feed me /KJV/Gen-Rev"). I'm
looking for any set of ways to improve its quality so it's a less bad demo
of how simply modules can be generically accessed.

Every time I hear people talking about wanting access to Sword materials in
JavaScript it keeps reminding me of how simple it is to build a web service
in Java to allow people to access that data in a web-happier way rather
than trying to read and parse modules in JavaScript.
