My process

This time I started by generating almost every component, service, and route at the beginning. The design is quite simple so it was easy to forecast what was needed. Also, I got a bit lazy and threw most of my styles (mixins, variables, atoms, etc) into just the one stylesheet. shrug

What I learned

I wanted another chance from scratch on using pure reactive techniques (vs imperative) in my code. I succeeded in getting everything to work without any direct subscriptions.

However, I had a number of issues getting things like combineLatest to work with BehaviorSubjects. The default value in a BehaviorSubject wasnt emitting when it was referenced in an Async pipe.

Honestly, I met my goal of fiddling with an API purely reactively and I started getting lazy at the end. I just wanted to wrap the project up.
