Value Swap

$ pnpm dlx shadcn@latest add @remocn/value-swap

Usage

ValueSwap renders an inline span that inherits the surrounding typography and swaps its content at the exact frames you pass in at — the outgoing value slides up and fades as the incoming one rides in from below, one continuous upward motion, while an invisible sizer holds the width of the longest value so the layout never shifts. It is the string analog of rolling-number for arbitrary text.

import { ValueSwap } from "@/components/remocn/value-swap";
 
export const MyScene = () => (
  <span style={{ fontSize: 40, fontWeight: 600 }}>
    <ValueSwap values={["$99", "$199"]} at={45} />
  </span>
);

Chain more than one swap by passing an array of frames, one per transition:

<ValueSwap values={["Draft", "In review", "Shipped"]} at={[30, 60]} />

A tight before/after pair reads best with a snappier swap — try duration={9} distance={9}. direction="down" mirrors the motion for downward narratives — a price dropping, a rank falling.

rolodex-flip is a 3D card flip with its own rhythm (interval) — reach for it when values cycle as a montage; ValueSwap is a flat vertical slide at explicit frames — reach for it for a point change (before → after, a status or price flip); rolling-number animates numeric digits individually.
