To reduce boolean prop proliferation in React, replace boolean flags with explicit component variants like ThreadComposer or EditMessageComposer. This composition pattern creates dedicated subcomponents, building flexible and maintainable UIs without complex prop combinations.

Use compound components with a shared context to compose complex UIs without prop drilling. Lift state into a context provider to enable cross-component state sharing, composing UI with a frame container and subgroup components.

React 19 API guidelines recommend using the use() hook over useContext for managing context providers. Following React 19 API changes like use() and avoiding forwardRef where possible ensures modern, reusable component API design.

The best way to design reusable React component library APIs is applying composition patterns like render props and explicit variants. Create a framed container using a Frame/Provider pattern to lift state and compose UI with dedicated subcomponents.

Use explicit component variants instead of boolean prop combinations when refactoring components to reduce boolean prop proliferation. This composition pattern builds flexible, maintainable UIs by replacing boolean flags with dedicated subcomponents.

To refactor a React UI component into a Frame/Provider pattern, select a target component and transform it into a framed container. Implement a shared context and provider to lift state, then compose UI with the frame and subgroup components.
