Metro Bundler

Metro is the JavaScript bundler for React Native, designed for sub-second reload cycles, fast startup, and quick bundling speeds. It handles thousands of modules in a single application and is integrated with every React Native project out of the box. Version 0.0.1 appears to be a fork (prn-metro-bundler) of the original Facebook metro-bundler, but the npm package seems to be a placeholder or mis-published. The original metro-bundler was previously part of the react-native repository and is now maintained separately. Note: The correct npm package for the official Metro bundler is 'metro' (or 'metro-bundler' as an alias), but the version 0.0.1 shown here is likely a test/published fork from a Chinese company (pinguo-zhangzhi).
