Catenate is deprecated in favor of optimus.
I had planned on catenate being a small library in a series of libraries for frontend optimization. Catenate was the one that concatenated your static assets into bundles.
Turns out that a lot of those optimizations you want to do on the frontend are tangled together. I was not able to do those improvements I wanted with this model.
So, when the API turned out quite different, I figured it would be better with a name that isn't so focused on concatenation - and more on optimization: optimus.
I do miss the concatenated cats tho:
I'm still using catenate, where are the docs?
You can find them in instructions.md.
How do I migrate to optimus?
This is catenate:
(-> app (catenate/wrap :bundles my-bundles :extra-files my-files :debug (:debug env) :public-dir "public"))
This is optimus:
(defn get-assets  (concat (assets/load-bundles "public" my-bundles) (assets/load-assets "public" my-files))) (-> app (optimus/wrap get-assets (if (:debug env) strategies/serve-unchanged-assets strategies/serve-frozen-optimized-assets)))
There's more code here, and less configuration. In other words, more power to you.
What do I get if I upgrade?
At the time of writing, there's this:
You can change your
get-assetsfunction in development-mode, and see those changes mirrored without a restart.
You can list files to include in bundles using regexp.
You get minification of scripts and styles.
You can serve optimized assets while developing, so that you are in a production-like environment, but with live reloads.
