To reduce boolean prop proliferation in React components, refactor multi-flag components into explicit variant components like ThreadComposer or EditMessageComposer, creating reusable APIs that avoid conditional rendering complexity.

Compound components in React are a composition pattern using a shared context to avoid prop drilling, enabling flexible assembly of related UI parts while maintaining internal state communication between parent and child components.

Yes, this React composition pattern guidance supports React 19 APIs, including adapting to the use() hook over useContext and implementing provider-based state lifting for modern context consumption.

The best way to decouple UI from state management in a React component library is lifting state into context providers, allowing cross-component access without prop drilling and separating data logic from rendering.

You should use explicit variant components instead of boolean props in React when a component handles multiple distinct UI states, preventing complex conditional logic and making the component API cleaner and more maintainable.
