Measured entry

tripled-scroll-progress-tracker-shadcnui

progressgradient-glowmotion on file

A client-side React scroll indicator shipped as a shadcn registry page. It reads document scroll with Framer Motion, springs a horizontal scale, and interpolates an indigo-to-pink fill. Optional section labels only switch the glow behavior; they are not rendered. Styling relies on Tailwind utilities and the bg-background theme token.

Verdict

Reliable in the harness and visually restrained, but the API overpromises: the height prop is unused, section strings never surface, and the component is not fixed without consumer styling. A reasonable pick for apps already carrying Framer Motion; otherwise a small CSS implementation is easier to own.

Use it if

  • You need a compact document-level progress strip with spring-smoothed motion.
  • Your app already uses Framer Motion and Tailwind theme utilities.
  • You can control placement and want an optional glow that reacts to section boundaries.

Skip it if

  • You need a genuinely fixed viewport tracker out of the box; the source renders in normal flow.
  • You expect section names, markers, or navigation controls to appear; the array is only used for progress segmentation.
  • You need the advertised height prop to change the bar; the source does not apply it.
  • Adding Framer Motion for one indicator is not acceptable for your dependency budget.

Install Framer Motion, keep the component on the client, and provide Tailwind utilities plus a bg-background color token. Without Tailwind, translate the utility classes into local CSS. Add fixed positioning yourself if the tracker should remain pinned while scrolling.
