Design systems that survive scale

A design system is easy to start and hard to keep. Most begin as a tidy component library and slowly rot into inconsistency as teams and products grow. Here's how to build systems that survive scale.

Tokens before components

The secret to a durable system is design tokens — a single source of truth for color, spacing, type and radius. Change a token once, and every component updates in lockstep.

@theme {
  --color-brand-500: #22c55e;
  --radius-card: 1rem;
  --space-section: 7rem;
}

Composition over configuration

Small, composable primitives beat giant configurable components. A handful of flexible building blocks combine into infinitely more than a dozen rigid ones.

• Tokens as the single source of truth
• Small primitives that compose freely
• Clear naming and documentation
• Versioning so changes don't surprise consumers

Document the why, not just the what

The components aren't the system — the decisions behind them are. When teams understand why a choice was made, they extend it consistently instead of fighting it.

“A design system isn't a library of components. It's a shared language for making decisions.”
