So a way to think about it is you've got an action, it goes into the epic.
And so, an epic is a function that takes a stream of actions dispatched, and returns a new stream of actions. But I'll show you how we can hook it up all together. Which again, I'm not gonna go all the way into, I will leave it as an exercise for you.
Redux observable code#
It doesn't seem that way, because a lot of the complexity when we see the code is RxJS. So it uses this idea of an epic, which obviously raises the next question, what is an epic? An epic is actually bizarrely simple, even though when we look at some of the code, it's not. Is taking things that we were doing 30, 40 years ago, and building libraries around our modern frameworks. There's a bunch of fun words for all these libraries, like Redux Saga, Users Saga, as in like what is that? It's a term from the '80s, again, like a lot of front-end thought leadership. Great, so the interesting thing is all of our Redux Observable has a thing called an epic.
Redux observable series#
You can start listening to the series of events, and much like an eventometer, you can stop listening when you're done. And then the cool thing about stream is that it's cancelable. Anything that happens over the course of time is probably a good candidate for an observable. It could be stuff off our website, it could be mouse movements, right? Where things are coming in, and this could be, for instance, things streaming in, when we hear back from the API. And observable you can think about as a stream, think about an array over the dimension of time. So Redux Observable, we should be pretty clear on the Redux part, but what is this observable? So we'll talk about enough RxJS to be dangerous, without getting kinda too deep into it. I think we aspire to use more, there's a lot more that we want to use, but currently, baby steps. This is kinda again beyond the scope of this, we use a very limited set of RxJS.
Redux observable full#
I'm pretty sure we have full courses on Observables, so I will not go all the way into Observables. > Steve Kinney: Redux Observable is effectively binding Redux to RxJS in the same way that React Redux binds Redux to React.
Special Guests: Ben Lesh, Jay Phelps, and Tracy Lee.Transcript from the "Redux Observable" Lesson What inspired you to write Redux observable?.Allows you to work with all different languages.Await values coming in from observables.What do Promises and Async/Await allow you to do?.Can Promises and Async/Await be mixed with observables?.Most common uses for getting started with observables.Means of encapsulating values you want pushed at you later on.Making everything functional in the library.What problems are observables trying to solve?.They also touch on what they like most about RxJS, how versatile it is, and more! They talk about what observables are and what they are trying to solve, the most common use cases for getting started with observables, and what Promises and Async/Await are. Tracy, Jay, and Ben are the RxJS ThisDot Media group and where they do support contracts for RxJS, staff augmentation, developer relations, and put on events. In this episode, the React Round Up panelists talk to Tracy Lee, Jay Phelps, and Ben Lesh about RxJS and redux-observable. Special Guests: Tracy Lee, Jay Phelps, and Ben Lesh
