Primitives
Primitives is a library of unstyled, accessible building blocks designed for creating complex interface elements in React. It functions as a headless component framework, providing the underlying logic, state management, and accessibility compliance while leaving all visual styling and design decisions entirely to the developer.
The library distinguishes itself through a composition-based architecture that allows developers to build interactive interfaces by nesting small, single-purpose components. This system automatically handles complex requirements such as WAI-ARIA attribute injection, focus management, and keyboard navigation. By intercepting and normalizing browser events, the framework ensures consistent interaction behavior across different input devices and browsers.
The components support both controlled and uncontrolled state patterns, allowing developers to either delegate state management to the library or override it for specific application requirements. This approach provides a foundation for custom design system engineering, where the structural and functional logic of interface elements remains decoupled from their appearance.
Features
