Scroll Thread

Install

Or by hand, in a Next.js project with shadcn set up. It writes components/pastetaste/scroll-thread.tsx.

Install the pastetaste component "Scroll Thread" (scroll-thread) into this Next.js project and use it.

What it is: A vertical line that draws itself beside content as you scroll, with a glowing head that follows the reading position. Optional wobble in the path.

Before you place it, ask me (one short message, in my language; "skip" = sensible default): which page and section it goes in, my brand colour (hex), the text, labels or images it should show, and whether I want my logo or my own copy in the demo content. Then:

Steps:
1. If the project has no components.json, run: npx shadcn@latest init -y -d. Then run: npx shadcn@latest add https://pastetaste.com/r/scroll-thread.json
   (it writes components/pastetaste/scroll-thread.tsx; install any npm packages it reports: motion@^12.23.0).
2. Import it: import { ScrollThread } from "@/components/pastetaste/scroll-thread" (check the file for the exact named export).
3. Put it where it fits on the page I name, keep the rest of the page untouched, and pass props for my colours instead of editing the installed file.
4. It does not depend on Tailwind; colours come from CSS variables (--pt-*) or props.
5. It supports prefers-reduced-motion with a still state; do not remove it.

Props (all optional unless the type has no default):
- children: ReactNode — The content the thread runs beside.
- color: string = var(--pt-accent, #2e63ff) — Thread and glow colour.
- width: number = 2 — Line width in px.
- side: 'left' | 'right' = 'left' — Which side the thread sits on.
- curve: number = 0 — Lateral wobble of the path in px; 0 is straight.
- className: string — Extra classes on the root.
- style: CSSProperties — Inline style overrides.

Then run the dev server, check it in the browser at desktop and mobile width, and tell me the page URL.
