Description

Adds a new Mosaic Avatar component built with StyleX, following the Button pilot's authoring pattern.

Props:

  • shape: circle (default) | square
  • size: lg | md (default) | sm | xs
  • src / alt: renders an <img> filling the clipped box; otherwise children render as the centered fallback

Styling notes:

  • Square shape uses a fixed 6px border radius for now (does not yet map to a --cl-radius-* token).
  • Sizes drawn from the spacing scale: xs 24px, sm 32px, md 40px, lg 48px, with fallback font-size scaling per size.
  • Emits the standard public contract: cl-avatar class + data-shape / data-size attrs, overridable via consumer className/style.

Swingset

Documented at /components/avatar (stories + MDX, wired into registry.ts and DocsViewer).

Preview: https://swingset-git-carp-mosaic-avatar.clerkstage.dev/components/avatar

📝 Walkthrough

Walkthrough

Adds a Mosaic Avatar compound component with StyleX styling, shape and size variants, image loading, fallback handling, ref forwarding, public exports, and tests. Swingset gains Avatar stories, MDX documentation, registry registration, and documentation route resolution. A minor changeset and repository import guidance are also included.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Add explicit return types to exported TypeScript functions.

The Avatar render callback and exported story functions currently rely on inference. Add explicit React element return types, using a type-only ReactElement import in the stories file if needed.

  • packages/ui/src/mosaic/components/avatar/avatar.tsx#L22-L25: annotate MosaicAvatar’s return type.
  • packages/swingset/src/stories/avatar.stories.tsx#L37-L39: annotate Primary.
  • packages/swingset/src/stories/avatar.stories.tsx#L41-L49: annotate Image.
  • packages/swingset/src/stories/avatar.stories.tsx#L51-L80: annotate Sizes.
  • packages/swingset/src/stories/avatar.stories.tsx#L82-L99: annotate Shapes.

As per coding guidelines, TypeScript functions, especially public APIs, must have explicit return types.

Reset canRender when delayMs changes. Switching from a delayed fallback to undefined leaves the fallback hidden, and changing to a new delay after it has already rendered skips the delay entirely. Reset the state in the effect and add a rerender regression test.

Removes the duplicate local status state and its sync effect in
Avatar.Image; the preload effect now reports load status directly to the
root, avoiding an extra render tick before the image mounts.
