Oftype Ngrx, The NgRx team created a ofType operator that allows us to filter out actions based on their type (s). In this video, we dive into the powerful world of NgRx, focusing specifically on the `ofType` operator and the `@ngrx/effects` library. Effects are subscribed to the Store NgRx effects are written by manipulating an action stream with RxJS operators. 'ofType' filters an Observable of Actions into an observable of the actions whose type strings are passed to it. So it is indeed called once. They extend the functionality of reducers by allowing actions to trigger more complex, asynchronous Filter for the desired action using the ofType() method. Because we don't want to trigger all the registered Effects when an action is dispatched, we can use the ofType operator. For example, if actions has type Actions <AdditionAction|SubstractionAction>, and The ofType operator filters this stream to only emit actions of type loadMorePhotos. This acts as a filter, and will only invoke the Effect when it receives the NGRX Effects handle side effects and asynchronous operations in an Angular application.
