Measured entry

motion-primitives-dock

hover-effect3dmotion on file

A client-side React dock composed from Dock, DockItem, DockIcon, and DockLabel exports. It ships as a shadcn registry TSX file, uses Motion for cursor-driven magnification and tooltip transitions, and expects Tailwind utility classes plus a cn helper resolved through the usual project alias.

Verdict

A polished, configurable dock for pointer-heavy React interfaces, with clean mounting and responsive behavior in the prepared harness. It does not work bare and needs a shadcn-style setup, including the expected utility helper and import alias.

Use it if

  • You need a desktop-style application launcher whose items enlarge as the pointer approaches.
  • You want composable dock items, icons, and hover or focus labels rather than a fixed menu schema.
  • Your React interface already uses Tailwind and Motion, so the component fits the existing stack.

Skip it if

  • You want to avoid adding Motion for a single navigation effect.
  • Your interface is primarily touch-driven, where cursor-distance magnification adds little value.
  • You require native button elements and their default semantics without adapting the dock item markup.
  • Your project does not use Tailwind and you do not want to translate the utility classes.

In a non-shadcn project, install Motion, provide Tailwind with the referenced utility classes, add a class-name merging helper compatible with cn, and either configure the source alias for that helper or change the import. Render it in a client-capable React boundary.
