Deprecation Guide for Deprecate the Ember Global

Accessing Ember on the global context (e.g. window.Ember, globalThis.Ember, or just Ember without importing it) is no longer supported. Migrate to importing Ember explicitly instead. See RFC 706 for more details.

Before:

export default class MyComponent extends Ember.Component {
  // ...
}

After:

import Ember from 'ember';

export default class MyComponent extends Ember.Component {
  // ...
}

Alternatively, consider converting to use the Ember modules API equivalent to the API you are using:

import Component from '@ember/component';

export default class MyComponent extends Component {
  // ...
}

If there is no modules API equivalent, consider refactoring away from using that API.
