Measured entry

magicui-word-rotate

text-effectunclassifieddo not usemotion on file

A client-side React text rotator distributed as a shadcn registry component. It cycles through supplied words with enter and exit animation from Motion, uses React state and an interval, and imports the shadcn-style cn class helper through an alias.

This entry is a do-not-use verdict

It is published because it broke, not in spite of it. The run stopped at the mount, and the recorded output is printed further down this page.

What the harness recorded

BARE BUILD

Verdict

A focused, customizable rotator that builds, mounts, and stays within its viewport in the prepared harness. It needs a shadcn-style setup as shipped because the bare build cannot resolve the aliased cn helper. Best for an existing Motion stack, not a lightweight standalone effect.

Use it if

  • You need a compact rotating word inside a hero line or promotional heading.
  • Your app already uses Motion and can absorb another animated client component.
  • You want callers to control the word list, timing, classes, and Motion transition props.

Skip it if

  • You want a dependency-free text effect, since Motion accounts for meaningful added bundle weight.
  • The changing phrase should not be rendered as a heading in your document structure.
  • You cannot guarantee a non-empty word list or add validation around the component.
  • Your interface should remain static unless you first add an explicit reduced-motion treatment.

Providerno provider required in the harness

In a non-shadcn project, install Motion, provide a cn-compatible class-merging helper, and replace or configure the aliased utils import. Use it in an environment that supports client-side React, and ensure the words prop is never empty.
