Rewrite to remove dependency on jQuery #111
Description
The assumption that a project even includes/uses jQuery is rather unsafe and unusual these days.
But the core of this project is still valuable in the modern post-jQuery Rails world, so it would be nice to keep the good parts and just remove the dependency on jQuery.
Looks like it wouldn't be too hard to rewrite app/assets/javascripts/xray.js without it.
While we're at it, consider:
- migrating from CoffeeScript to a regular modern ES6+ module, and
- making it so wan include the module into our Webpack JS pack (remove the dependency on/assumption of Sprockets too)...
