What different design decisions should we consider when building a reusable component?
💡 Model Answer
Key design decisions include: 1) API shape – decide which props are required, optional, or deprecated. 2) Composition strategy – children, render props, or slots. 3) State management – internal vs. controlled. 4) Styling – CSS modules, styled‑components, or CSS variables. 5) Accessibility – ARIA roles, keyboard support, and focus management. 6) Theming – expose a theme context or tokens. 7) Performance – memoization, lazy loading, and avoiding unnecessary re‑renders. 8) Testing – unit tests, snapshot tests, and accessibility audits. 9) Documentation – clear README, usage examples, and API reference. 10) Versioning – semantic versioning and backward compatibility.
