Measured entry

shadcn-progress

progressunclassifiedmotion on file

A client-side React progress bar that ships as a TypeScript shadcn registry file. It wraps the Radix Progress primitive, animates the indicator with utility classes, and depends on React, radix-ui, Tailwind theme classes, and the shadcn cn helper imported through a project alias.

Verdict

A sensible fit for an existing shadcn codebase, with straightforward styling and Radix semantics. It needs a shadcn-style setup to build and mount, and consumers must supply an accessible name before shipping it.

Use it if

  • Your app already follows shadcn conventions and needs a compact determinate progress indicator.
  • You want Radix progress semantics while retaining direct control over classes and component source.

Skip it if

  • You need a drop-in package that works without project aliases, a cn utility, or Tailwind theme tokens.
  • You cannot add an accessible name wherever the component is used, since the verified demo leaves the progressbar unnamed.
  • You need built-in indeterminate behavior or status text rather than a value-driven bar.

In a non-shadcn project, install radix-ui, provide the aliased cn utility or replace that import, configure the Tailwind utilities and primary theme token used by the classes, and add an accessible label at each usage site.
