babel-preset-react-native

A Babel preset for React Native applications, providing the default Babel configuration used by React Native's Metro bundler. This preset is deprecated and has been replaced by metro-react-native-babel-preset for React Native v0.57 and later. The last version (4.0.1) supports Babel 6; users on newer versions must migrate. Key differentiator: it was the official preset before React Native switched to Babel 7, enabling custom Babel configs while preserving baseline transforms.
