@camelburrito we're going to leave this one. We're not entirely sure how to navigate firebase to do it as intended and are just going to focus on the bugs from PRs for now.

Sure , this should be basically put your JS functions in your own file and have urls like /template/travel/search etc. This is pretty much json config + moving files around.
