feat: add Badge and Avatar MDX components - #170
Merged
Conversation
Register Apsara's Badge, Avatar, and AvatarGroup as MDX components so content can label status inline and show user images. Using any component inside a heading previously failed to compile: fumadocs' rehypeToc exports each heading as JSX evaluated at module scope, where MDX components are not in scope, so `### Limits <Badge>Beta</Badge>` threw `Badge is not defined`. Replace it with a toc that exports plain-text titles, which is what both themes already reduce them to. The `[toc]` and `[!toc]` heading tags are preserved.

The CLI bundle and fumadocs-mdx can resolve fumadocs-core/mdx-plugins to separate module instances, so the imported rehypeToc is not the same object as the one in the plugin list and the identity filter missed it. Both toc plugins then ran and the build failed with "Duplicated export 'toc'". Match on function name as well, and drop any toc already in the tree before exporting ours so a duplicate can never reach the parser.

…ports
Splicing a `[toc]`-only heading out of its parent shifted the next
sibling into the visited index, so `SKIP` stepped over it and that
heading never reached the toc. Return the adjusted index instead.
Removing an upstream toc dropped the whole ESM node, taking any binding
declared alongside it. Strip just the `toc` binding — including an
aliased `export { upstreamToc as toc }` — and remove the node only once
it exports nothing.

Registers Apsara's

Badgeis a<span>,Avatarhas no internal state.Components in headings
Using any component inside a heading failed to compile before this change:
fumadocs-core'srehypeTocconverts each heading to estree and emitsexport const toc = [...]at module top level, where MDX components aren't in scope. Not specific toBadge—<CalloutTitle>in a heading fails identically today.rehype-toc-text.tsreplaces it with a toc whose titles are plain strings. Both themes already reduce toc titles to text (themes/default/Toc.tsxvianodeToText,themes/paper/ReadingProgress.tsx), so nothing downstream changes except that inline markup in a heading (## The \id` field) now reaches the toc as text rather than aelement. fumadocs'[!toc](omit from toc) and[toc]` (toc-only, dropped from the page) heading tags are preserved.It's wired through the function form of
rehypePlugins— the array form inserts beforerehypeTocrather than replacing it.Testing
