Ever heard about ephemeral state? Ngrx, ngxs, akita etc did a great job in managing global state in SPAs. However, nobody talked about the complexity and pain of managing the components state. As a result of my studies, you will get an overview of terms and ways to categorize state. You know the tricky problems and challenges and learn how to craft component state reactively. If you attend this talk you will learn about: - In-depth problems of reactive state management - Subscription-less components - Component state management - Handling side-effects You will be able to write fully reactive components that will be well structured and organized without any effort. As a side effect, the application will work (nearly) automatically zone-less.
