About

@human-kit/ui is an open-source library of typed, accessible UI components for Svelte 5. It gives you the difficult parts — the semantics, the keyboard operation, the focus control, and the state — as parts that have no styles. You assemble these parts into your own design system.

Principles

• Headless. Each component controls its behavior and its accessibility, but never its appearance. You write the styles that you want, and no component changes them.
• Accessible from the start. Each component obeys a known interaction pattern. Read Accessibility.
• Typed. Each prop, part, and event has full TypeScript types. Thus your editor helps you, and a refactor stays safe.
• Composable. Each component gives you small parts (Root, Trigger, Content, Item) that you assemble. No component is one large element with many props.
• Small. The package is native ESM, and each component has a subpath export. Thus your bundler includes only the components that you import.

The tools in this library

• Svelte 5 and its runes.
• TypeScript, in the full library.
• Floating UI, for the position of the overlays. The library adds its own presence, focus, and layer-stack code above it.

The API and the interaction contracts come from Base UI and React Aria. These two projects set the standard for accessible, composable, headless components. @human-kit/ui adapts their patterns to Svelte, and this library is possible because of their work.

Status

The library is in public beta (1.0.0-beta). The API is almost stable, but small changes can occur before version 1.0.0. The Releases page shows each change.
