Measured entry

motion-primitives-text-scramble

text-effectdark-futuristicmotion on file

A client-side React text effect that replaces unrevealed characters on a timer, then resolves them to the supplied string. It ships as a shadcn registry TypeScript component, imports motion/react, and relies on React state and effects. It accepts a custom element, character set, timing controls, a trigger, and a completion callback.

Verdict

A compact, configurable scramble effect that builds and mounts cleanly without framework scaffolding. It is a good fit for occasional decorative reveals, but teams should add reduced-motion handling and avoid treating it as a general solution for text that changes after mount.

Use it if

  • You need a short decoding or terminal-style reveal for a heading, status, or one-line label.
  • Your React interface already uses Motion or can justify adding it for this and other animation work.
  • You want to restart the effect from application state and run logic when the reveal completes.

Skip it if

  • The text changes frequently while the trigger remains active, because child updates do not restart or synchronize the displayed value.
  • You need built-in reduced-motion behavior rather than adding that preference handling around the component.
  • You want a dependency-free text effect or cannot justify Motion for a small decorative interaction.
  • The changing text sits in a live or frequently announced region where rapid character updates could distract assistive technology users.

Providerno provider required in the harness

In a non-shadcn React project, install Motion, copy the component into your source tree, and keep it behind a client boundary where the framework requires one. No provider, theme variables, or registry helper utilities are required. Add your own reduced-motion policy and styling through the rendered element or class name.
