@hazelcough, Michelle Bu
At Stripe, there were a lot of developers who needed that tiny bit of CSS to ship something.
There was a lot of nesting. Almost arbitarily, causing things to be designed three times over. Meant you could never grep for anything. This problem caused the three levels of CSS degredation:
MVP features. Yay, we brought in Sass and we shipped the thing!
We improve features, introduce a few bugs, and there's some code stink but it's okay! We'll fix it later.
Everything still works! Errr monkey no see/no hear/whatever, it's fine. It's fine.
Everything is growing so friggin' fast. CSS is growing at three poops per week.
We need conventions. So, at Stripe they started a component library.
Developers who didn't know CSS used it in their other internal projects. It meant that they didn't have to bother designers for it when they just wanted to get something up quickly.
Coming up with a convention style speed up developers and kept people from arbitarily adding CSS to the bottoms of Sass files.
Abstracting away components allows them to easily change things.
Enter the Rework framework!
Testing is hard because of all of the states CSS has.
There are already a bajillion component libraries, I thought!
With your own component library, you're able to spend 90% of your time building the components and 10% on polish. If we think about CSS first, we can think about CSS less.
