react-composition

To scale React component APIs without boolean prop proliferation, replace boolean flags with compound components and shared context. This composition-first approach lets each consumer compose behavior independently, keeping the API surface clean and maintainable during refactors.

The best way to manage shared state across sibling React components is lifting state into shared context providers. Keep state inside provider boundaries and expose typed interfaces for state, actions, and metadata so siblings collaborate safely without tangled state flows.

To refactor a React toolbar using compound components, replace conditional boolean switches with composable elements. Apply architecture, state management, and implementation pattern guidelines to arrange the toolbar so consumers assemble behavior without inflating the component's API surface.

Yes, this React composition approach works with React 19 APIs. The guidelines include specific React 19 rule priorities for applying compound components, shared context providers, and typed state interfaces across admin and customer product experiences.

You should avoid using boolean props in React components when multiple flags overlap or create conditional rendering chaos. If consumers need varied combinations of behavior, switching to compound components prevents brittle state flows and keeps the API scalable.
