downgradeComponent

any

A helper function that allows an Angular component to be used from AngularJS.

Part of the upgrade/static library for hybrid upgrade apps that support AOT compilation

This helper function returns a factory function to be used for registering an AngularJS wrapper directive for "downgrading" an Angular component.

@paraminfo{ component: Type<any>; downgradedModule?: string | undefined; propagateDigest?: boolean | undefined; inputs?: string[] | undefined; outputs?: string[] | undefined; selectors?: string[] | undefined; }

contains information about the Component that is being downgraded:

  • component: Type<any>: The type of the Component that will be downgraded
  • downgradedModule?: string: The name of the downgraded module (if any) that the component "belongs to", as returned by a call to downgradeModule(). It is the module, whose corresponding Angular module will be bootstrapped, when the component needs to be instantiated.

(This option is only necessary when using `downgradeModule()` to downgrade more than one Angular module.) - `propagateDigest?: boolean`: Whether to perform ChangeDetectorRef#detectChanges on the component on every [$digest](https://docs.angularjs.org/api/ng/type/$rootScope.Scope#$digest). If set to `false`, change detection will still be performed when any of the component's inputs changes. (Default: true)
