原標題：How to use private API of the Spartacus library

注意：這只是一個折中方案。

Disclaimer: The private API of Spartacus should not be used in general. It may change at any time without any warning. You can use the following workaround on your OWN RISK. It might result in breaking your code after upgrading to any next version.

具體做法

Open file node_modules/@spartacus/xxxxx/spartacus-xxxxx.d.ts and find the exported alias name for the class, prefixed with symbol ?:

export { SomeClass as ?xyz } from '..........';

Then you can use the alias in your application, for example to extend the class behavior:

import { ?xyz as SomeClass } from `@spartacus/core`;/* ... */// for example: @Injectable() export class CustomSomeClass extends SomeClass { /*...*/ }/* ... */ @NgModule({providers: [{ provide: SomeClass, useClass: CustomSomeClass }] })

WARNING: the ?-alias might change in any next release of Spartacus without any warning. It’s not a part of the public API.

如下圖所示：
