MOX ROCKSS!! Hands-on Elixir & OTP

Hello everyone,

I’m extremely happy to announce that I’ve released a new Elixir video titled “Mox Rockss”. The video focuses on using Mox to mock out dependencies in a non-trivial project. It skims over behaviours and shows that Mox provides great flexibility by allowing function bodies to be defined from the tests.

Authorization and Policy Scopes with Elixir/Phoenix

Authorization is usually an important part of any application, but it is also something that is not very often talked about. This post discusses authorization techniques and also an opinionated way of organizing your authorization code within Phoenix Contexts and Ecto Schemas.

Elixir makes it really easy to roll up a Mock server to test WebSocket clients.

This post discusses about a very high level overview of implementing a long running connection between two services with the use of WebSocket and then writing unit tests for the functionality.

Livebook as a Business Intelligence tool

Livebook may have been created for machine learning, but because it can connect to your live running app, it means you can also use the graphing and analysis tools for doing Business Intelligence (BI)!

Check out this guide that walks you through connecting Livebook to your app running on Fly.io and start gaining insight!

ThinkingElixir 057: Scaling Live Chat with Cade Ward

In episode 57 of Thinking Elixir, we sat down with co-host Cade Ward to hear how he and his team tackled a problem of hosting live web chats with crowds of 120K+ users coming together for live events. On the show, we have talked with a couple guests with similar bursting high-load situations. Cade had been through it too so it was time to dig in and cover how this situation can be solved. We cover the different attempts and temporary solutions used and the final solution that has been working really well. In fact it works so well, during a recent event, the auto-scaling didn’t kick in and everything was still fine!

Highlights for the 4th GUI task in LiveView: an interactive timer.

Lots of fun challenges. I used LiveView hooks (which are great) and was very proud not to introduce an actual timer until the very last step of the project.
