metro-babel-register

A babel/register configuration specifically for Metro, the JavaScript bundler for React Native. Version 0.84.3 is the latest stable release, with monthly releases on the Metro 0.84.x branch. It provides a pre-configured Babel require hook that enables on-the-fly transpilation of Node.js modules during Metro's build process. Key differentiators: it is deeply integrated with Metro's own Babel presets and plugins, ensuring compatibility with React Native's transform pipeline. Unlike generic `@babel/register`, this package automatically applies Metro's custom transforms and ignores, matching the bundler's internal behavior. It is designed for development-time use, typically in custom Metro plugins or scripts that need to evaluate source files with Babel. No external dependencies beyond @babel/register and @babel/core.
