The decision inside it

The release is the moment, not the press

The burst plays on release and only when the release lands on the button, the same rule a native click follows. Slide off and nothing celebrates. Holding longer lets go harder, so the effect answers how it was pressed.

When to use it

Use Pressure Button for one action worth a moment of weight, like publishing or sending: tap it, or press and hold to charge it. Not for everyday buttons.

Installation

How you get it

Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.

Use Liro's Pressure Button for this.
Install it: npx shadcn@latest add @liro/pressure-button
(the @liro registry is set up in components.json, with LIRO_KEY in .env.local)
Import it from @/components/ui/pressure-button.
Do not rewrite or restyle it. Pass my data through its props
and keep its built-in states.

For the full brief with every prop and the mistakes assistants usually make, use Copy prompt above. Free components install through the @liro registry with your CLI token: see the Namespaced tab.

Usage

components/publish-button.tsx
import { Rocket } from "lucide-react";
import { PressureButton } from "@/components/ui/pressure-button";

export function PublishButton({ onPublish }: { onPublish: () => void }) {
  return (
    <PressureButton onClick={onPublish}>
      <Rocket />
      Publish release
    </PressureButton>
  );
}

States

All of them are drawn by the component. None is left for you to design.

  • Rest
  • Pressed
  • Charging
  • Burst
  • Disabled
  • Reduced motion

Accessibility

  • Keyboard reachable throughout, in visual order
  • Focus trapped in overlays, Escape closes them
  • Focus returns to whatever opened it
  • Live regions announce what changed, not that something did
  • Honours prefers-reduced-motion

Responsive behavior

  • Sizes to its container, not the viewport
  • Usable from 320px up
  • Pointer-based interaction, so trackpad and touch both work
  • No hover-only affordances
