size?: 'sm' | 'md' | 'lg';
loading?: boolean;
disabled?: boolean;
children: React.ReactNode;
}
function Button({ variant = 'primary', size = 'md', loading, disabled, children }: ButtonProps) {
return (
<button
className={`btn btn-${variant} btn-${size}`}
disabled={disabled || loading}
aria-busy={loading}
>
{loading ? <Spinner /> : children}
</button>
);
}
Governance
- Review Committee: Approves new components
- Contribution Process: RFC → Review → Implementation
- Versioning: Semantic versioning for releases
- Deprecation: 3-month notice with migration guide
Best Practices
- Start with foundational tokens
- Document every component thoroughly
- Ensure WCAG 2.1 AA compliance
- Support dark mode from the start
- Include usage guidelines with do/don't examples
