Headless components
Compose documentation navigation and content with Foldkit views and typed state.
Fumadocs exposes React hooks and components from its Core package. Foldocs keeps the same responsibilities headless but expresses them through pure Core helpers, Foldkit views, and explicit application messages.
| Capability | Foldocs API |
|---|---|
| Breadcrumb context | navigationContextForUrl from foldocs-core |
| Documentation shell | docsLayout from foldocs-ui |
| Landing shell | landingLayout from foldocs-ui |
| Markdown links | renderMarkdown from foldocs-ui |
| Table of contents | CompiledPage.toc plus DocsLayoutActions.selectToc |
There are no React providers or hooks. State stays in the Effect/Foldkit program, and view functions remain deterministic.
Package boundary
foldocs-core derives serializable navigation state. foldocs-ui turns that
state into Foldkit HTML. The foldocs runtime owns browser effects such as
scrolling, intersection observation, clipboard access, and URL navigation.
