Create application state interface.
As with any NgRX application, we need to create a new app.state.ts file. We recommend creating is file in a root state directory, located at src/app/state. Import the IEntityState
interface from @briebug/ngrx-auto-entity as well, as we will be using it later.
Define the AppState
interface as normal. We will eventually define each entity state property here. For now, we've left it blank, and will fill it in later on in this quick start.
Remember to export the AppState
type so that it may be used throughout the rest of your app.
