Retrospective on Fela

I really appreciate a real-world walkthrough of a technology. Not only in what that technology does, but why it was chosen and how it worked for a team. Anybody can read the docs, but what you know after years of real-world usage is far more valuable. Hugo “Kitty” Giraudel:

I want to properly reflect on the choice of going with Fela instead of any other CSS-in-JS library you might have heard of.

I’d never heard of Fela before. To me, the most interesting part is the “atomic” output. It looks like it combines all uses of unique property: value pairs into a unique class and then applies all the necessary classes to the necessary DOM node. I’m sure the result of that is some pretty gnarly looking class output. (I’d suggest putting reasonably named styling hooks on things too, for humans.) But I would think that the chunk of CSS that gets generated and applied to the page is ultimately as small is it can be as it contains nothing repetitive. That’s one the advantages of any well-configured atomic class workflow: tiny CSS.
