Uncaught TypeError: regeneratorRuntime is not a function

It is now.

This is an addon that'll import the 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

Compatibility

  • Ember.js v3.12 or above
  • Ember CLI v2.13 or above
  • Node.js v12 or above

Installation

ember install ember-maybe-import-regenerator

Usage

This exists to give applications that still service IE11 users and also wish to use async/await or generators.
