场景:我有2个库项目,即lib1和lib2,以及一个应用程序项目,即lib-app,它使用了先前创建的2个库。
在lib-app中,我已经使用服务类实现了发布和订阅模式。
在lib-app notificationService中
export class NotificationService {
/*Publish method*/
emitActiveEditor$: Subject<any> = new BehaviorSubject<any>(null);
emitActiveEditorInfo(any: any) {
this.emitActiveEditor$.next(any);
}
/*subscribe mehthod*/
get emitActiveEditorChange(): BehaviorSubject<any> {
return (this.emitActiveEditor$ as BehaviorSubject<any>);
}
}
现在在lib1库中,我发布如下消息
import { NotificationService } from 'dist/muvi6-utilities';**//this import show error**
constructor(private notificationService: NotificationService) { }
ngOnInit() {
this.notificationService.emitActiveEditorChange();
}
在lib2中,我订阅
import { NotificationService } from 'dist/muvi6-utilities';**//this import show error**
constructor(private notificationService: NotificationService) { }
ngOnInit() {
//this.notificationService.emitActiveEditorChange();
this.notificationService.emitActiveEditorChange.subscribe(result => {
if (result) {
alert("Hello Received in Lib2" +result)
}
});
}
在这里,我无法导入NotificationService表单Lib-app
谁能告诉我该怎么做? 基本上,我想从lib1中的组件发布并在lib2中订阅它,反之亦然。
