Thinking Reactively with RxJS - Egghead.io Workshop

Pre-requisites

Software

Verify your computer has the following installed:
- git (verify by running git --version)
- node v8.9.3 or greater (verify by running node --version)
- npm (verify by running npm --version)
Clone this repo and cd into it
Run npm install
Test if you can run the app: npm start
- You should see a browser window open at http://localhost:3000
- And after a few moments, an app with two tabs and two buttons

Helpful knowledge

The main pre-requisite for this course is to have some experience with RxJS and its most popular operators. All of the below operators and theory will be covered in the course as well, but given that they are not the focus of what we want to teach, we will not spend too much time on them. The more time you spend on the below, the easier it will be to solidify everything during the workshop.

Intro for beginners:

Introduction to Reactive Programming

Operators

RxJS Beyond the Basics - Operators in Depth Highly recommended, it explains scan, combineLatest, merge, startWith and a few other operators we will use in the course

Recommended for understanding the shareReplay(1) usage in the workshop and also Subjects: https://egghead.io/courses/rxjs-subjects-and-multicasting-operators

Check out the OPERATORS.md for a complete list of operators we'll use in the course, along with links to resources and sandbox Stackblitz environments where you can play around with them.

Promises

Understanding the ES6 Promise API

Bonus / Further learning

All around incredibly good course around higher order observables and different merging strategies in RxJS: Use Higher Order Observables in RxJS Effectively

During the workshop

The only files we'll use/work on during the workshop are below:

root
└── solutions-bonus-exercises
    ├── 01-understanding-the-problem
    ├── 02-build-a-counter
    └── ..etc.
└── src
    ├── lesson-code
   	    ├── TaskProgressService.js <-- MAIN WORK AREA
	    └── EventCombo.js
        └── Extensions.js
└── README.md

We'll mainly work in TaskProgressService.js

We'll go through the different stages in the workshop.

If you ever get stuck, the solutions to each stage are in the solution-bonus-exercises folder.

If you finish a stage early, you can check out the solutions-bonus-exercises/stage-we-are-at/EXTRA.md file for some extra questions/work.

If you join late, you can, at any point, type git checkout stage-X, where X is the current stage we're at, and it will bring you up to date with all the latest changes we've been making.

After the workshop, you can see a the complete, built project, by typing git checkout final-solution.

If you want to practice a specific operator more, check out the OPERATORS.md file for links to Stackblitz sandboxes for that specific operator.

After the workshop

Finish the app we started in class
Complete all the extra assignments for each stage in the solutions-bonus-exercises folder
Think of a different way to implement the following requirements from the course:
- show delayed
- hide delayed
- key combo
If you haven't yet, go through all the pre-requisites above and read more about the operators/mechanics we discussed in the course
