babel-plugin-polyfill-corejs3

A Babel plugin that automatically injects imports for core-js@3 polyfills based on the target environment. It works with @babel/preset-env's built-ins and useBuiltIns options to only include necessary polyfills. Version 0.14.2 supports @babel/core ^7.4.0 or ^8.0.0-0 (<8.0.0). Key differentiators: it is part of the official Babel polyfills family, replacing the older @babel/polyfill and babel-polyfill packages; it handles direct core-js imports without needing a separate transform; and it avoids injecting polyfills that are already supported by the target environment, reducing bundle size. It is actively maintained by the Babel team.
