ngx-store: displatchDataToStore should not return

[WHeirstrate]

Currently, the dispatchDataToStore() method has a return type, which means the data attribute will have a return type.
A short example to allow for better explanation:

dispatchDataToStore(actions.example, this.apiService.someMethod<SomeDataType>(someValue), store, 'add');

Currently, the dispatchDataToStore method will return SomeDataType. (Reference)

This is done so that we can further work with the value set to the store, like for example:

dispatchDataToStore(actions.example, this.apiService.someMethod<SomeDataType>(someValue), store, 'add').pipe(map((value: SomeDataType) => value['someKey']));

The issue that arises, is that this voids the SSOT (Single Source Of Truth). If the latter example were to be wrapped in a method and called from a service, method, or component, it would be possible to assume that the value of example in the store is of type typeof someKey.

As a matter of principle, the dispatchDataToStore should return void or undefined. This forces the user to switchMap to the value in the store, which restores the SSOT principle.

This is a breaking change.
