RxResourceOptions

A function that returns the Observable to load the resource's value from.

This Observable must eventually emit a value or an error before it completes — a resource needs one of those two things to know what to show. If the Observable completes without ever emitting anything (for example because of catchError(() => EMPTY)), Angular throws RESOURCE_COMPLETED_BEFORE_PRODUCING_VALUE (NG0991), since it has nothing to give the resource.

A reactive function which determines the request to be made. Whenever the request changes, the loader will be triggered to fetch a new value for the resource.

If a params function isn't provided, the loader won't rerun unless the resource is reloaded.

The value which will be returned from the resource when a server value is unavailable, such as when the resource is still loading.

Equality function used to compare the return value of the loader.

Overrides the Injector used by resource.

Identifier used to cache the resource data in the TransferState during server-side rendering and to retrieve it on the client side. This value value needs to be identical for both the client and server.
