Measured entry

ruixen-motion-file-tree

transition-effectunclassifiedmotion on file

A client-side React file tree that recursively renders files and folders, keeps expansion and selection state internally, and animates nested groups with Motion. It ships as a shadcn registry component and depends on Motion, Lucide icons, Tailwind theme classes, and a local cn utility backed by clsx and tailwind-merge.

What the harness recorded

BARE BUILD

✗ Build failed in 1m 22s
error during build:
[vite:load-fallback] Could not load <sandbox>/src/lib/utils (imported by src/cut/components/ruixen/motion-file-tree.tsx): ENOENT: no such file or directory, open '<sandbox>/src/lib/utils'

Verdict

A sound choice for a small animated file browser when its intentionally narrow API is enough. It builds and mounts in the prepared harness, but the bare failure confirms that it needs a shadcn-style setup, including the expected utility alias and theme classes.

Use it if

  • You need a compact, read-only project or document navigator with animated folder disclosure.
  • Your app already uses shadcn conventions, Tailwind theme tokens, and the local cn helper.
  • Uncontrolled expansion state and a simple node-selection callback fit your interaction model.

Skip it if

  • You need controlled expansion, lazy loading, editing, drag and drop, or virtualization for a large tree.
  • You require full keyboard tree navigation and keyboard selection behavior beyond folder toggling.
  • You want to avoid adding Motion and an icon package for a small navigation widget.

Providerno provider required in the harness

In a non-shadcn project, install Motion, Lucide React, clsx, and tailwind-merge; add a cn helper at the expected utility alias or rewrite that import; and provide Tailwind styles plus the accent, muted, primary, and foreground theme tokens used by the component.
