What problem does it solve?
It solves the maintainability problems caused by prop-heavy, boolean-prop-driven React component APIs that become hard to extend, reason about, and test.
Core Features & Use Cases
- Replace boolean props with composition to avoid combinatorial UI states and make intent explicit.
- Build compound components with context to share state without prop drilling, improving scalability of shared UI patterns.
- Use children over render props for simpler, more readable component APIs when the parent does not need to supply dynamic rendering data.
- Decouple state implementation from UI so consumers depend on stable interfaces while providers can swap underlying state sources.
- Provide explicit variants and layout slots to prevent “one component does everything” designs and to support structured insertion points.
- Use headless/polymorphic patterns (e.g.,
as props) to maximize flexibility for design systems and shared component libraries.
Quick Start
Apply the modern composition patterns to a prop-heavy component by rewriting boolean modes into explicit subcomponents and/or compound components that manage shared state via context, then use children-based slots for structured insertion points.
