My Observable Will Go On! | Jan-Niklas Wortmann | ng-conf 2021
68Near, far, wherever you are
I believe that my Observable does go on
Why does using RxJS sometimes feel like navigating a ship through a sea of icebergs? The chance of hitting an iceberg with a ship is maybe low, but using Observables without fully understanding their underlying lifecycle makes the chance of hitting icebergs in your code very high. RxJS, like a powerful, luxurious steam ship, can be intimidating and even dangerous when you do not fully know what you are doing.
Let me guide you through avoiding those icebergs by teaching you the lifecycle of an Observable. Do you know why `catchError` should be placed on an inner Observable? Do you know why `takeUntil` should usually be placed as the last operator, but sometimes not in edge cases? This talk will make you understand those concepts to help you see through the RxJS fog along your coding cruise and avoid hitting any icebergs that may appear.
