Measured entry

ruixen-mouse-spark

background-effectunclassified

A client-side React canvas that emits colored particles under the pointer. It ships as a single shadcn registry UI file, uses React hooks and browser canvas APIs, and declares no external component dependencies. Its props control the canvas dimensions and light or dark color palette.

Verdict

Use it as a decorative flourish only if you are prepared to own a few interaction details. It builds and mounts cleanly without a shadcn shell, but its blank idle state is expected, touch users get no effect, and pointer placement assumes the canvas begins at the viewport origin.

Use it if

  • You want a pointer-following particle trail as a decorative layer in a desktop-focused hero or demo.
  • You can give the canvas explicit dimensions and place it at the viewport origin or adjust its coordinate math.
  • You prefer a self-contained canvas effect with no animation library or provider.

Skip it if

  • The effect must respond to touch, keyboard input, or reduced-motion preferences without modification.
  • The canvas will sit inside an offset container and you cannot correct the viewport-relative pointer coordinates.
  • You need meaningful content before pointer movement, since the canvas starts blank.
