How To Migrate Your Angular Application State Management From Observable To Signals

#tutorial #angular #rxjs

If you are an Angular developer, you might be familiar with the concept of Observable, which is a way of handling asynchronous data streams in your application. Observable allows you to subscribe to data changes and react accordingly, using operators like map, filter, switchMap, etc. Observable is a powerful tool for managing complex and dynamic data flows, but it also comes with some drawbacks, such as:

You have to manually unsubscribe from the Observable when you are done with it, otherwise you might create memory leaks or unwanted side effects.
You have to deal with error handling and retry logic in case the Observable fails or emits an error value.
You have to use RxJS library, which adds some extra weight and complexity to your codebase.
