[RxJS] Reactive Programming - Using cached network data with RxJS -- withLatestFrom()

So now we want to replace one user when we click the 'x' button. To do that, we want: 1. Get the cached network data for generating the userList. 2. Then get a random user from the cached data. 3. Showing the user in the list. We have the function to…

[RxJS] Reactive Programming - What is RxJS?

First thing need to understand is, Reactive programming is dealing with the event stream. Event streams happens overtime, which not stay in the memory. For example, the array we have: var source = ['1', '1', 'foo', '2', '3', '5', 'bar', '8', '13']; W…

[RxJS] Reactive Programming - Clear data while loading with RxJS startWith()

In currently implemention, there is one problem, when the page load and click refresh button, the user list is not immediatly clean up,it is cleared after the new data come in. So two things we need to do, 1. Hide User Elements when the user object i…

[RxJS] Reactive Programming - Sharing network requests with shareReplay()

Currently we show three users in the list, it actually do three time network request, we can verfiy this by console out each network request: var responseStream = startupRequestStream.merge(requestOnRefreshStream) .flatMap(requestUrl => { console.log…

[Reactive Programming] Async requests and responses in RxJS

We will learn how to perform network requests to a backend using RxJS Observables. A example of basic jquery request: console.clear(); var requestStream = Rx.Observable.just('https://api.github.com/users'); //Current requestStream is just a stream //…

[RxJS] Reactive Programming - New requests from refresh clicks -- merge()

Now we want each time we click refresh button, we will get new group of users. So we need to get the refresh button click event stream: var refreshButton = document.querySelector('.refresh'); var refreshClickStream = Rx.Observable.fromEvent(refreshBu…

[RxJS] Reactive Programming - Why choose RxJS?

RxJS is super when dealing with the dynamic value. Let's see an example which not using RxJS: var a = 4; var b = a * 10; console.log(b); a = 5; console.log(b); So you change a, it won't affect b's value because b is already defined.... So if you want…

[Reactive Programming] RxJS dynamic behavior

This lesson helps you think in Reactive programming by explaining why it is a beneficial paradigm for programming. See how reactive programming helps you understand the dynamic behavior of a value evolving over time. It allows you to specify the dyna…

.Net中的反应式编程(Reactive Programming)

系列主题:基于消息的软件架构模型演变 一.反应式编程(Reactive Programming) 1.什么是反应式编程:反应式编程(Reactive programming)简称Rx,他是一个使用LINQ风格编写基于观察者模式的异步编程模型.简单点说Rx = Observables + LINQ + Schedulers. 2.为什么会产生这种风格的编程模型?我在本系列文章开始的时候说过一个使用事件的例子: var watch = new FileSystemWatcher(); watch.C…
