I built a Hacker News client with Angular 2 (https://angular2-hn.firebaseapp.com) and shared it here a short while ago (https://news.ycombinator.com/item?id=12438119). Got some very useful feedback and thought it would be nice to write a post on how I built it. I go through building the entire app step by step from scratch solving each problem along the way.

As always, I hope you find it useful and would appreciate any feedback.
