Design Systems That Survive Launch
Most component libraries rot the week after launch. A few habits keep them alive.
A design system is easy to start and hard to keep. The first ten components are a joy. The hundredth is a graveyard of one-off variants nobody remembers adding. Survival is about discipline, not tooling.
Tokens before components
Color, spacing, radius, type - settle these as variables first. Components that read from tokens bend with the brand instead of breaking. Components with hardcoded values become technical debt the moment the palette shifts.
One way to do each thing
Two buttons that look identical but live in different files is how a system dies. Every duplicate is a future inconsistency. When you catch one, merge it the same day.
Document the why, not the what
The props are self-evident from the types. What isn’t obvious is why a pattern exists - the edge case it protects against. Write that down, or watch someone “simplify” it back into the bug it was built to prevent.
