metro-react-native-babel-transformer

Babel transformer for React Native applications, part of the Metro bundler ecosystem. Current stable version is 0.84.3 (released 2025-04). Release cadence is frequent patches and minor versions. Key differentiator: it is the default transformer in React Native projects, handling JSX, Flow, and React Native-specific transforms. It integrates with Metro's caching and module system. Alternatives like @babel/preset-react are lower-level and do not include React Native's custom plugin set.
