In v3.6 MongoDB rolled out Change Streams, which allow you to easily subscribe to all data changes on a collection, database, or entire deployment. This tutorial is an adaption of a tutorial put out by the good folks at Pusher.com. In fact, it uses the exact same front-end React app (because my purposes is exploring the backend implementation). The idea is to create a simple TODO list application that recieves real-time updates via Pusher web-sockets.

I recently decided to pick up Clean Code by Rober C. Martin (a.k.a Uncle Bob). This is one of those seminal books in software development all devs are encouraged to read. As one of the top selling books on software development since it was published in 2009, there are no shortage of reviews. So I don’t think there’s anything I can add there. I will just say that I enjoyed it and you should read it.
