Learn how to build production-ready Angular 2 applications by building a bug tracking app!

This course continues where Angular 2: Forms left off - make sure you’ve completed that before beginning.

We’ll be working on our bug-tracking application, Bugged Out. We’ll start by creating a bug update method, showing you how to update existing records in our Firebase database. We’ll also display our bug data with tables, and get to know listeners, which allow us to perform actions only when data has changed or certain conditions have been met.

By the end of this final installment, Bugged Out will be complete - you’ll know how to take an Angular 2 app from idea to production, and you’ll have a functional bug-tracking app for your next projects.

This is part seven of a seven part series. Get the full benefit by completing them in order:

Oh yeah, and the whole SitePoint library! Learn More.
