or using yarn:

yarn add babel-plugin-polyfill-es-shims --dev

Usage

Add this plugin to your Babel configuration:

{
  "plugins": [["polyfill-es-shims", { "method": "usage-pure" }]]
}

This package supports the usage-pure and usage-global methods.

Supported polyfills

This polyfill provider is compatible with polyfills that follow the es-shims-api specification. Those polyfills must live under the @es-shims organization, but for historical reasons some of them are owned by different people: they are explicitly marked as such in the following tables.
