Measured entry

shadcn-tooltip

tooltipunclassified

A client-side React tooltip wrapper built from Radix Tooltip primitives. It ships as copy-in source with provider, root, trigger, portalled content, and arrow exports, and relies on radix-ui plus the shadcn cn helper, theme tokens, and utility classes for styling and motion.

Verdict

A sensible pick inside an existing shadcn codebase: the Radix foundation is sound and the wrapper stays easy to customize. It does not mount bare and needs a shadcn-style setup, so adoption outside that ecosystem requires deliberate plumbing.

Use it if

  • You already use shadcn conventions and want a tooltip that fits the same component and theme structure.
  • You need accessible hover or focus hints with portal-based positioning and configurable Radix behavior.
  • You want source-owned markup and classes that your team can adjust directly.

Skip it if

  • Your project does not use Tailwind utilities or shadcn theme tokens and you do not want to recreate the styling layer.
  • You need rich interactive popover content rather than a short explanatory label.
  • You want a package component that works without copying source or maintaining local utility conventions.

Install

Bare installfails once the shadcn-style helpers are removed, so it needs that setup
Providerno provider required in the harness

In a non-shadcn project, add radix-ui, provide the cn class-merging helper and its import alias, configure the referenced Tailwind utilities and animation variants, define the foreground and background theme tokens, and ensure client components are supported. Wrap tooltip usage in TooltipProvider.
