ui-component-design

Design modular UI components with consistent APIs and documentation to create a shared component library. This approach reduces duplication, accelerates development across teams, and ensures visual and behavioral consistency by establishing base architecture, variant systems, and accessibility standards once.

Use BEM-based CSS patterns for predictable styling, JavaScript class and factory patterns for component logic, and clear separation of concerns in your base architecture. This structure supports scalability, makes components testable, and enables teams to maintain and extend components without conflicts.

Implement ARIA attributes, semantic HTML, and keyboard navigation as part of your base component design. Document accessibility requirements alongside variant states and test against assistive technology to ensure your component library meets standards for all users.

Yes. Embed usage examples, test suites, and documentation directly in your component library so developers can reference and verify behavior without leaving the codebase. Self-contained components reduce onboarding time and prevent documentation drift.

Yes. The component library supports all common UI elements—buttons with primary and secondary variants, inputs with states like disabled and loading, cards with configurable layouts—shared across multiple applications through a consistent props schema and API.

A component library provides versioned, tested, documented components with standardized variants and states, enabling teams to ship consistent interfaces at scale. Ad-hoc styling repeats patterns across projects, increases maintenance burden, and risks visual inconsistency.
