To avoid boolean prop proliferation in React components, refactor conditional flags into explicit variants and compound components, utilizing shared context providers to manage state cleanly.

The best way to manage shared state in compound components is by lifting the state into context providers, allowing flexible state sharing across nested components without excessive prop drilling.

Yes, these React composition patterns support React 19 compatibility by adopting the use() hook in place of useContext and using normal refs instead of forwardRef for effective component architecture.

To refactor a chat message composer for multiple modes, implement explicit component variants and compound components with shared context, preventing prop overload when supporting edit, thread, and forward modes.

You should use compound components in React when building scalable, maintainable component APIs that require flexible state sharing across related sub-components without relying on complex boolean conditionals.
