# ember-maybe-import-regenerator [![CI Build](https://github.com/machty/ember-maybe-import-regenerator/actions/workflows/ci-build.yml/badge.svg)](https://github.com/machty/ember-maybe-import-regenerator/actions/workflows/ci-build.yml)

> Uncaught TypeError: regeneratorRuntime is not a function

It is now.

This is an addon that'll import the
[Regenerator](https://github.com/facebook/regenerator)
Runtime in your Ember app, but only if you didn't already set
`babel.includePolyfill` to true. This is useful for:

1. Apps that want to use ES6 generator functions (including `async/await`) but don't want to
   import the large ~30kb (gzipped) Babel polyfill. This package adds ~2kb (gzipped).
2. Addons that depend on generator functions (or other addons
   that depend on generator functions) but don't want to
   force users to have to add `babel.includePolyfill: true` to
   their config files (like ember-concurrency, ember-power-select), but
   shouldn't double import regenerator-runtime if the user already
   has `includePolyfill: true`
