How to use the @angular/upgrade.UpgradeAdapter function in @angular/upgrade

import { UpgradeAdapter, UpgradeAdapterRef } from '@angular/upgrade';

// This is really strange. But you need the module when you create 
// the upgrade adapter, but you also need the created upgrade adapter
// when creating the Module (see below, the call to upgradeNg1Component)
// so we use a forwardRef, and we have to put the upgradeAdapter and the 
// module in the same file
export const upgradeAdapter = new UpgradeAdapter(forwardRef(() => AppModule));

// ng2 services

// Create ngUpgrade Adapter
// ---
// `forwardRef` is required for initalizing the `UpgradeModule`
// after it is included below. See reason below for more info.
// ---
// See: https://angular.io/docs/js/latest/api/core/index/forwardRef-function.html
export const adapter = new UpgradeAdapter(forwardRef(() => UpgradeModule));

// the upgrade main module
// ---
// This must be required after the `UpgradeAdapter` is initialized.
// If not, then when `UpgradeModule` import `CommonModule` which needs
// to a reference to the adapter so it can upgrade a component and
// put in the global common module.
// ---
// See: https://github.com/angular/angular/issues/11069
const { UpgradeModule } = require('app/upgrade.module.js');

// Bootstrap ui-router
uiRouterNgUpgrade.setUpgradeAdapter(adapter);
