Thinking Reactively with RxJS

Submitted Dec 12, 2017

Handling the flow of asynchronous data streams has always been a challenging task. Callbacks offer the quick solution. Then came promises which made it easier to write and maintain code around such data streams. Reactive programming is another take on the problem. With implementations in languages like .net, java, scala, JavaScript etc, with big names like Google, Microsoft, Netflix actively supporting and maintaining implementations of the idea in these languages, the style of programming is here to stay.
JS community has been appreciating the ease it brings in given the asynchronous nature of the language. Angular has adopted it as a core library, React-redux uses it. It’s safe to bet that the javascript implementation, RxJS if used in the right way can help in many ways.

Outline

We start off by introducing what reactive programming is, explains the core concepts and key terms of the style of programming - data streams, observables, observers, operators, subjects, subscription etc
We then go ahead to see how we set up each of these components, how to connect them and how the data flows among them
With this understanding we can now compare Reactive components with promises and look at the problems it solves
Next we see how RxJS implementation works. We understand various reactive components in terms of RxJS
To get a better hands-on idea, we take a look at the implementation of a real world example with a relatively complex logic in RxJS

Requirements

None, all the code exaples would be provided on JSBin

Speaker bio

(I have spoken at national & International events. Most recent being the above talk at Nerd Summit at UMass Amherst, Massachusetts, USA.)

I started off with android rom development, was a device maintainer for CynogenMod before it blew up. A small freelance project for a startup got me into web development. I’ve been consulting in web domain ever since, taking up training sessions, both online and offline and hacking around in general. I’ve consulted couple of multi-billion dollar companies.
Everything I know is self-taught, I know firsthand how important role the community plays when it comes to learning new technologies in this fast paced environment and I like to give back to it in whatever form I can.
