Measured entry

animata-animated-beam

background-effectgradient-glowmotion on file

A React wrapper that places animated diagonal light streaks and a faint grid behind supplied children. It ships through a shadcn registry as a TSX component plus colocated CSS, uses Tailwind utility classes and the conventional cn helper, and needs no provider or third-party runtime package.

What the harness recorded

BARE BUILD

✗ Build failed in 35.34s
error during build:

Verdict

A solid decorative backdrop that builds, mounts, and stays contained across the tested layouts. Reduced-motion handling is included, but the bare mount fails because it needs a shadcn-style setup, specifically the shared utility alias and compatible Tailwind styling.

Use it if

  • You need a dark animated backdrop behind hero copy or a compact callout.
  • Your app already uses Tailwind and the usual shadcn alias and cn helper.
  • You want motion that automatically disappears when reduced motion is requested.

Skip it if

  • Your design must remain light, restrained, or visually quiet behind content.
  • You cannot adopt Tailwind utilities or maintain the colocated animation stylesheet.
  • You want a standalone package that works without project aliases and shared utilities.
  • You need an interactive connection diagram rather than a decorative background.

Bare installfails once the shadcn-style helpers are removed, so it needs that setup
Providerno provider required in the harness

In a non-shadcn project, add or replace the cn helper, configure the at-sign source alias, provide a compatible Tailwind setup for the utility classes, and copy the CSS file so the keyframes and reduced-motion rule load with the component.
