Being proactively Reactive with Rxjs
In today's world, our applications need to be both responsive, fast and scalable. Our applications need to respond to user interactions such as mouse movements, clicks and inputs as well as asynchronous inputs like XHR calls, server sent events, setInterval, even web socket events! Unfortunately as things stand today, there is no consistent way to deal with the myriad of different “changes” that could happen in an application.
But what if there is? This is what Reactive Extensions (specifially RxJs in this session) allow us to do. It offers us an abstraction that allows us to treat everything from DOM events (infinite streams) to our domain (maps, sets and arrays) as streams. This consistent interface now permits us to create and manipulate any source identically. Futhermore, it allows us to react to different sources as if they are one!
Reactive Extensions are fast becoming the de-facto approach of managing asynchronicity in JS land. From Netflix's UI to Angular 2 $http to ES7 - reactive programming is everywhere!
This session is RxJs 101, covering
- A brief introduction to reactive programming
- How reactive programming is analogous to dataflow programming
- The architectural patterns underlying reactive extensions
- How we can create and manipulate “observable” streams within our applications
- Error handling
- Hot and Cold observables
- The reactive landscape, and a couple of gotcha
If we have time we will look at a simple demo, and reactive progamming's role in Angular 2
About Raju Gandhi
Raju is a software craftsman with almost 20 years of hands-on experience scoping, architecting, designing, implementing full stack applications.
He provides a 360 view of the development cycle, is proficient in a variety of programming languages and paradigms, experienced with software development methodologies, as well an expert in infrastructure and tooling.
He has long been in the pursuit of hermeticism across the development stack by championing immutability during development (with languages like Clojure), deployment (leveraging tools like Docker and Kubernetes), and provisioning and configuration via code (toolkits like Ansible, Terraform, Packer, everything-as-code).
Raju is a published author, internationally known public speaker and trainer.

In his spare time, you will find Raju reading, playing with technology, or spending time with his wonderful (and significantly better) other half.
