Hyunsui is a headless UI library for web app. It does not include styles; instead, each component focuses solely on accessibility, state management, and semantic structure.

All visual presentation and rendering behavior are designed to be fully controlled by developers, enabling seamless integration with existing design systems through a developer-experience-focused API.

Components are provided without any styles applied, allowing you to have full control over both design and developer experience. You can style the components using any styling solution of your choice. For more details, please refer to the guide for each component.

Hyunsui components are designed to be customized to suit your needs. Our open component architecture provides you granular access to each component part, so you can wrap them and add your own event listeners, props, or refs.

Where applicable, components are uncontrolled by default but can also be controlled, alternatively. All of the behavior wiring is handled internally, so you can get up and running as smoothly as possible, without needing to create any local states.

One of our main goals is to provide the best possible developer experience. Hyunsui provides a fully-typed API. All components share a similar API, creating a consistent and predictable experience.

Hyunsui is still under active development.
