March Meetup: Intro to RxJS:(Tour of Heroes)+NgRx Jest Testing w/ Jesse Sanders

Welcome to the March Meetup!

This month we have an out of town presenter that is also speaking at ng-conf this year: Jesse Sanders! He'll be giving two short-form presentations:

Intro to RxJS (Tour of Heroes)
What is all the buzz around NgRx and how do I learn to implement it? We will dive into NgRx, when to use it, and how to implement it. We will start with our ubiquitous Tour of Heroes quick start example code and show you how to implement NgRx. We will cover actions, reducers, and effects so you will understand what the purpose is for each one and how to create them. We will convert each page in Tour of Heroes to NgRx and also show you how to use libraries like NgRx-Actions to reduce boilerplate and simplify the code. In closing, we will briefly talk about how to test your application using jest.js.

ngrx Jest Testing
Everybody know how important testing is and yet many of us have projects without tests, commented out tests, or testing disabled. In a perfect world, we build our new project with tests and everything is great until we get asked to refactor the application and now have hundreds of broken tests. In addition, I may have implemented my project with NgRx and I have a whole new set of items to test; actions, reducers, and effects. Jest.js makes testing regular and NgRx projects a breeze. I'll show you how to install and start testing with Jest.js with zero configuration. We will dive into serializers to simplify the output and explore how to test simple functions as well as actions, reducers, and effects. I'll show you how easy it is to test your components and know that they will render exactly the way you expect. I'll also be showing you how your refactor with hundreds of broken tests can be fixed in a matter of minutes.
