A React Native utility that provides CSS-like transform-origin functionality for better 3D transform animations.
react-native-anchor-point is a React Native utility library that provides CSS-like transform-origin functionality for 3D transform animations. It allows developers to set custom anchor points (like pivot points in Android or anchor points in iOS) for transforms, enabling more realistic and complex 3D rotations and animations. This solves the limitation in React Native where transforms default to rotating around the center, making advanced animations difficult.
React Native developers building apps with complex 3D animations or UI effects, particularly those needing precise control over transform pivot points similar to CSS or native platforms.
Developers choose this library because it fills a specific gap in React Native's animation capabilities, offering a simple, lightweight solution for anchor point control without requiring native code or complex workarounds.
Provides a function like transform-origin in css, anchor point in iOS, pivot point in Android. It makes3D transform animation better in React-Native.

Enables setting custom pivot points for transforms, similar to CSS transform-origin, as demonstrated in the example with rotateX and perspective for realistic 3D effects.
Provides a single `withAnchorPoint` function that easily integrates with existing transform styles, making it straightforward to adopt without overhauling animation code.
Delivers consistent transform behavior across iOS and Android, mimicking standards from CSS and native platforms, as highlighted in the key features.
Works with 3D properties like perspective, rotateX, and rotateY, enabling complex animations as shown in the GIF examples of rotating elements.
Only addresses anchor point control, so for complete animation solutions, developers need to pair it with other libraries like React Native's Animated or Reanimated, adding complexity.
The README provides only a basic example; advanced usage, edge cases, or integration with other animation tools are not covered in detail, which might hinder adoption.
3D transforms can be resource-intensive on mobile devices, and this library doesn't include optimizations for smooth animations at scale, relying on React Native's underlying performance.
