Installation

npm install framer-motion

// Copy component from
src/components/animations/TracingBeam.tsx

Usage

import TracingBeam from '@/components/animations/TracingBeam'

// Wrap your long-form content — the beam traces scroll progress along the left side
<TracingBeam>
  <article>
    <h2>Section 1</h2>
    <p>Your long content here...</p>

    <h2>Section 2</h2>
    <p>More content...</p>
  </article>
</TracingBeam>

Prompt Preview

Copy a prompt that recreates this UI

Paste this into your AI coding assistant to generate code that closely matches the reference, including color, size, shape, typography, spacing, and polish.

Copy-ready AI prompt

Starts from the current visual reference and project constraints.

Build a animations component named TracingBeam in React/Next.js.
Goal: recreate the same overall UI and behavior as the TracingBeam reference from a component gallery.
What it needs to communicate: Scroll-progress side beam that traces reading position down the page..

Project constraints:
- Use Next.js 16.2.6 with the App Router, React 19, TypeScript strict mode, and Tailwind CSS v4.
- Do not create a tailwind.config.js file. Use Tailwind v4 utilities and CSS variables where design tokens are needed.
- If you are implementing this inside the same project, use the Prompt font via next/font/google. If not, use the closest equivalent typeface.
- Return production-ready code with imports, responsive behavior, keyboard accessibility, and polished empty, hover, focus, active, and disabled states where relevant.
- Match the reference closely: color palette, spacing scale, border radius, shadows, icon scale, typography hierarchy, and motion timing.

Component-specific expectations:
- Recreate the same visual motion while keeping the implementation performant.
- Respect prefers-reduced-motion and make timing/easing intentional.
- Avoid unnecessary dependencies unless the behavior truly requires them.
- No explicit color literals were found in the examples. Match the live reference and the project accent color when appropriate.

Props to support:
- children: React.ReactNode — required — Long-form content to trace
- className: string — Additional CSS classes

Reference usage patterns:
- No examples were documented. Infer a sensible default presentation and one richer usage example.

Feature expectations:
- useScroll + useTransform
- Glowing dot
- Gradient fade tail
- Hidden on mobile

Output requirements:
- Return complete code, not pseudocode.
- Include all necessary imports and helper types.
- Keep the implementation accessible, responsive, and visually finished.
- Match the reference for color, size, shape, typography, spacing, and interaction states as closely as possible.
- If multiple files are needed, organize them cleanly and explain the file structure briefly.

Tweak only product-specific copy or data after the first generation pass.
