Avoid boolean prop proliferation by refactoring React components into explicit variant components. This approach uses compound components and generic context interfaces to ensure scalable composition and a robust, dependency-injected UI.

The best way to share state across non-nested compound components is using provider-based state lifting. This technique utilizes generic context interfaces containing state, actions, and meta to enable dependency injection and improve testability.

Adapt React context providers for React 19 by replacing useContext with the use() API and passing refs as regular props. This modernizes context interfaces and supports scalable composition patterns.

Use explicit variant components instead of boolean props when building reusable component libraries. Variants prevent prop combination conflicts and enable scalable composition using compound components, render props, and context providers.

Yes, this composition pattern works for large component libraries. It refactors codebases relying on compound components and context providers into composable building blocks, applying generic context interfaces for reusable UI.
