Reusable UI Primitives & Design Systems
A design system provides stable primitives such as Button, Input, Dialog, Stack, Text, and FormField. These primitives should encode accessibility and consistent behavior so product features do not reinvent them.
Avoid a giant component with dozens of boolean props. Prefer composition and variants with clear semantics.
A design system is a product and engineering contract: changes can affect many consumers, so versioning, documentation, visual testing, and migration strategies matter.
Variant-oriented button
type ButtonProps = {
variant?: "primary" | "secondary" | "danger";
children: React.ReactNode;
};💡 Explicit variants communicate supported design decisions better than arbitrary style flags.
Key Takeaways
- Centralize accessibility-critical primitives.
- Prefer explicit variants over boolean-prop explosions.
- Treat design-system APIs as stable contracts.
