To refactor React components and avoid boolean prop proliferation, replace conditional props with compound component patterns and lift state into context providers. This creates modular, context-aware subcomponents instead of a single monolithic component cluttered with conditionals.

The compound component pattern in React structures complex UI into modular, context-aware subcomponents. This mechanism eliminates prop drilling by allowing subcomponents to implicitly share state through a parent provider.

Manage state injection for a multi-mode React component by decoupling state management from the UI and lifting state into providers. This allows for dependency-injectable state across different explicit component variants like thread, edit, or forward modes.

Yes, you need React 19 to use the use hook for context state management. Adhering to React 19+ patterns is required for standardizing component architecture, including the use hook and explicit component variant definitions.

The best way to structure a flexible React UI library API is applying compound component patterns and context-based state management. This standardizes component architecture by enabling dependency-injectable APIs rather than relying on monolithic structures.
