Callstack introduces react-native-fast-shimmer, an open-source library for creating smooth shimmer loading skeleton effects in React Native apps. Built on react-native-reanimated for off-thread animation and react-native-svg for responsive gradients, it uses a single shared animated value to drive all shimmer components simultaneously, minimizing performance overhead. Setup requires wrapping the app in a ShimmerProvider and placing Shimmer components anywhere in the tree. The library supports Expo, offers full customization, and has a roadmap including directional shimmers and glimmer effects.
