Aboutgithub.com

This monorepo holds @space-man/react-theme-animation, a React theming library with animated theme transitions. It ships setup guides for the Next.js App Router and Pages Router, TanStack Start with cookie-based SSR, and Vite single-page apps. A ThemeProvider and a useTheme hook control the theme. The project uses the MIT license.

For an agent

Use it when a theme switch needs a visible transition, such as a circular reveal. Test it with reduced motion turned on, and keep the switch instant in that case.

Why it is here. It packages the theme-transition effect with SSR setups that avoid a flash of the wrong theme.
