3 Strategies to Enhance the Value of Common React Components: Scalable Design, Native Element Usage, and Accessibility

Introduces design strategies that go beyond simple reuse of common components in React development to enhance project quality and maintainability. The core principles are designing extension rules, utilizing native elements, and considering web accessibility.

1. Designing Extension Rules

• Clear Role Definition: Avoid all-in-one components and clearly define component boundaries according to the Single Responsibility Principle. It is more maintainable to inherit from or compose Base components to create new variant components when necessary.
• Interface Policy: Handle major design variations with the variant prop and ensure flexibility through rest parameters and interface inheritance, but limit the scope of inheritance to consider the risks of overriding due to excessive property exposure and the difficulty of refactoring.

2. Utilizing Native Elements

• Hiding Elements: For complex UIs (e.g., checkboxes), hide native <input> elements using opacity: 0 and overlay them with styled elements to implement the design while maintaining browser default features (form submission, accessibility, etc.).
• Control Method: Consider the pros and cons of Controlled and Uncontrolled approaches, but recommend a hybrid approach that operates internally as Controlled while offering users the flexibility of Uncontrolled usage.
• Ref Forwarding: All input components must apply forwardRef to ensure compatibility with external libraries such as react-hook-form.

3. Web Accessibility and Usability

• Applying ARIA: Explicitly specify role, aria-selected, aria-controls, etc., for complex components like tabs and modals to help screen readers understand the structure, thereby enabling the creation of semantic test code.
• Semantic Tags and Interactions: Enhance UX by directly implementing user-friendly interactions such as closing with the ESC key and navigation with arrow keys, along with the use of appropriate semantic tags.
