問題：https://stackoverflow.com/questions/65815289/how-to-share-cmscomponentdata-between-several-components-in-spartacus-manner/65820581#65820581

Let’s imagine that we have CMS Component:

ConfigModule.withConfig(<CmsConfig>{cmsComponents: {CMSSupportComponent: {component: SupportButtonComponent,},}, }),

But from inside we have to open another Angular component which also needs the same CMSComponentData. Simple Angular component relates to the same Angular module.

I know that we can do it via Angular Service, common for Angular manner (this requires some handy work). But maybe Spartacus has some approaches similar to:

ConfigModule.withConfig({cmsComponents: {SearchBoxComponent: {providers: [{provide: SearchBoxComponentService,useClass: CustomSearchBoxComponentService,deps: [CmsComponentData, ProductSearchService, RoutingService]}];}} });

and we can share injected CmsComponentData via single Service for several components.

解答

as defined in Spartacus documentation:

The CMS data that is related to a component is provided to the component by the CmsComponentData service during instantiation. The CmsComponentData service contains the component uid, and also data$, which is an observable to the component payload. By making use of the Angular dependency injection (DI) system, components and component-specific services can use the CmsComponentData.

it’s recommended way to use Angular DI to inject CmsComponentData service and used in your components.
