building-compound-components

You share contextual state across React components by using a Context pattern to wire unstyled UI primitives together, enabling multiple compound parts like Root and Trigger to access shared state without prop drilling.

The best way to build a headless UI component library is by enforcing separation of concerns between behavior and presentation, using Radix-style architecture with Slot-based rendering and data attributes for styling.

You implement asChild composition and ref forwarding by adopting a Slot-based rendering approach, which allows unstyled React primitives to pass props and refs through to child elements dynamically.

Yes, compound components enforce separation of concerns by wiring contextual state and behavior logic internally while leaving presentation entirely to the consumer through unstyled primitives and data attributes.

Building Radix-style compound components requires robust TypeScript typings to ensure type-safe context sharing, ref forwarding, and render-prop APIs across the unstyled UI primitives.

You should not use the compound components pattern for simple UI elements that do not require shared contextual state, as the Context wiring and Slot-based rendering architecture add unnecessary complexity.
