Measured entry

motion-primitives-text-effect

text-effectdark-futuristicmotion on file

A client-side React text animation component that splits a string by character, word, or line and applies configurable Motion variants. It ships as copied TSX from a shadcn registry and depends on Motion plus a project-local cn utility backed by clsx and tailwind-merge.

What the harness recorded

BARE BUILD

src/cut/demo.jsx (2:10): "default" is not exported by "src/cut/index.jsx", imported by "src/cut/demo.jsx".

Verdict

A flexible, focused text reveal primitive with clean preset and customization options. It needs a shadcn-style setup, and the bare demo also assumes a default export that the source does not provide, so expect a small integration fix outside that environment.

Use it if

  • You need reveal and exit animation for short headings, labels, or campaign copy.
  • Your React app already uses Motion and can host a client component.
  • You want presets with an escape hatch for custom variants and transitions.

Skip it if

  • Your text content contains links, emphasis, or other React nodes rather than a plain string.
  • Your performance budget cannot justify adding Motion for a small text flourish.
  • You require reduced-motion behavior to be built into the component rather than added by your team.

For a non-shadcn project, install Motion, clsx, and tailwind-merge; add a compatible cn utility; configure the project alias or replace that import; preserve client-component support; and import TextEffect by its named export.
