About Sling Button
Sling Button turns sending into a gesture: pull it back and the band stretches while the icon tilts, then let go past the mark to fire it off. A plain click still sends, so nobody is forced to play.
Sling Button is an input component for React 19, styled with Tailwind CSS 4 and animated with Motion. It drops into Next.js, Vite, Remix or Astro through the shadcn CLI as a single file you own.
When to use Sling Button
- Send buttons in chat and email.
- Launch and publish actions.
- Playful submit buttons.
- Game-like interfaces.
How it works
The pull distance is tracked with pointer capture and drawn as a stretched band. Release beyond the threshold calls onFire, anything shorter springs back, and a click or Enter fires immediately.
It is a real form control: it has an accessible name, works with the keyboard alone, shows a visible focus ring and announces its state to screen readers. With prefers-reduced-motion on, it holds still or settles instantly instead of animating.
Customizing Sling Button
Every prop is documented in the API reference above with its type and default. The ones you will reach for first are listed here.
The Customize panel next to the preview lets you change pull live, and the Code tab updates to match, so the snippet you copy already carries your values.
- label (string, default "Send").
- pull (number, default 70).
