About Error Shake
Error Shake gives wrong input a decaying head shake, as a wrapper or a useShake hook for any Motion element.
Error Shake is an UI transition 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 Error Shake
- Login and PIN errors.
- Form validation.
- Wrong answers in quizzes.
- Failed actions.
How it works
The shake is a keyframed x offset with decreasing amplitude.
The change it animates is also announced to assistive tech, and the motion is short enough never to block what the user wants to do. With prefers-reduced-motion on, it holds still or settles instantly instead of animating.
Customizing Error Shake
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 strength, label live, and the Code tab updates to match, so the snippet you copy already carries your values.
- trigger (number): Increment to shake again.
- strength (number, default 8): Peak offset in px.
- useShake(strength) ({ controls, shake }): Hook form for any motion element.
