Installation

pnpm dlx shadcn@latest add @bundui/scroll-progress-bar-01

Requires @bundui in the registries of your components.json (shadcn adds official directory namespaces automatically).

Usage

usage.tsx
import ScrollProgressBar from "@/components/scroll-progress-bar";export default function Example() {  return <ScrollProgressBar type="bar" />;}
  • Give users continuous visual feedback on their position in long-form content.
  • Improve orientation on documentation, articles, landing pages, and other vertically scrolling layouts.
  • Use as a lightweight alternative to visible section navigation or a table of contents.
  • Place near the top of the viewport when the page has enough content to require scrolling.

Examples

Article progress indicator

Add the bar to a long article or documentation page.

article-progress-indicator.tsx
import ScrollProgressBar from "@/components/scroll-progress-bar";export default function ArticlePage() {  return (    <>      <ScrollProgressBar type="bar" />      <main className="mx-auto max-w-3xl space-y-8 px-6 py-16">        <h1 className="text-4xl font-bold">Product Guide</h1>        <p>Long-form product documentation content goes here.</p>        <p>Additional sections continue down the page.</p>      </main>    </>  );}

Landing page

Use the default component configuration at the top level of a scrolling landing page.

landing-page.tsx
import ScrollProgressBar from "@/components/scroll-progress-bar";export default function LandingPage() {  return (    <>      <ScrollProgressBar />      <section className="flex min-h-screen items-center justify-center">        <h1 className="text-5xl font-semibold">Build better interfaces</h1>      </section>      <section className="flex min-h-screen items-center justify-center">        <p className="max-w-xl text-center">Explore the features below.</p>      </section>    </>  );}

Reading layout

Pair the progress bar with a centered reading column and enough content to produce meaningful progress.

reading-layout.tsx
import ScrollProgressBar from "@/components/scroll-progress-bar";export default function ReadingPage() {  return (    <>      <ScrollProgressBar type="bar" />      <article className="prose prose-neutral mx-auto max-w-2xl px-6 py-20">        <h1>Design Systems at Scale</h1>        <p>Use this layout for essays, changelogs, and technical articles.</p>        <p>More reading content continues through the remainder of the page.</p>      </article>    </>  );}

API reference

PropTypeDefaultDescription
type"bar" | "circle""bar"Selects the scroll progress presentation. The default is the bar variant; the documented example uses `"bar"`.

Accessibility

  • The component is a visual progress indicator and does not replace a heading, navigation landmark, or readable page structure.
  • Keep sufficient color contrast between the progress bar and its background, especially when customizing its styling.
  • Provide meaningful landmarks and content structure so users who cannot see or perceive the animation can still understand and navigate the page.
  • If the surrounding page includes animated scrolling or other motion, consider honoring the user’s reduced-motion preference at the page level.
