Simple component theming with broccoli.js

My team and I have been working on a new internal component library to share across a few Ember apps. The library is an Ember addon in a private github repo. So far, so good. The off-the-beaten-path part of our requirements is that the components need to be themeable. Specifically, we support a color and a "light" or "dark" aesthetic.

We want a great developer experience for creating and updating these components, so we used ember-freestyle as a devDependency of the library to create a living style guide. We added some UI to allow theme switching and even a checkbox to switch themes every second (thanks ember-concurrency!).

The thing that gave us the biggest challenge was figuring out how to author and apply the styles that were necessarily dynamic. Specifically, the css rules that used the dynamic color.

We decided to organize our styles like so:

return v.toString(16);
You can’t perform that action at this time.
