Frontend Components

Reusable React components require clear prop interfaces, single responsibilities, and explicit TypeScript typing. Design each component to handle one task—like `ChartDisplay` or `FilterControls`—with well-defined props, making them composable and easy to maintain across multiple projects.

Manage component state by keeping it local when possible, using hooks in React and reactive properties in Vue. Design components with single responsibilities so state changes remain predictable; pass data via props and use composition patterns to avoid prop drilling and maintain clarity.

Build consistent component libraries by defining explicit prop typing, documenting usage patterns, and applying single-responsibility principles to each component. Ensure all components follow the same naming conventions and interface patterns so developers can predict behavior and compose them predictably.

Yes, modularity principles—clear interfaces, single responsibilities, and composition patterns—apply across React and Vue. Both frameworks support reusable, focused components; adapt the specific syntax (hooks vs. reactive properties) while maintaining consistent design patterns.

Single-responsibility components are easier to test, maintain, and reuse. When a component does one thing well—like sorting data or rendering a chart—it becomes predictable, testable, and composable into larger features without hidden dependencies or side effects.

Reusable components must support accessibility standards and be testable in isolation. Design props and APIs to expose semantic HTML, ARIA attributes, and clear event handlers; document these so maintainers can verify accessibility and write tests without coupling to implementation details.
