In this post I will show you a simple pattern to decouple your Phoenix context so that you can specify from your controller how you want to preload your Ecto.Query.

At The Flatiron School, we leveraged Elixir’s GenServers and Dynamic Supervisors to “deploy” large amounts of content to our students faster and less error-prone than ever before. https://www.thegreatcodeadventure.com/how-we-used-elixirs-genservers-dynamic-supervisors-to-build-concurrent-fault-tolerant-workflows/

This article is all about Automating Phoenix Development & Deployment using Gitlab CI/CD.

I found how to pattern match a function on Improve error messages for invalid expression in match · Issue #5649 · elixir-lang/elixir.

x = &List.first/1
case &List.first/1 do
  ^x -> true
end

I also wrote a summary for it: How to pattern match a function in Elixir - dsdshome

Feel free to check it out and leave some comments.

Being new to Elixir and Phoenix, I spend quite some time in the projects’ documentation. One thing that stood out for me recently is the first sentence of Phoenix’s Plug documentation: “Plug lives at the heart of Phoenix’s HTTP layer and Phoenix puts Plug front and center.”

So naturally, I felt compelled to take a deeper dive into Plug and understand it better. I hope the article helps you out as well, you can read it here.

https://medium.com/blackode/how-to-perform-hot-code-swapping-in-elixir-afc824860012

Hot code swapping is replacing or adding components without stopping or shutting down the system. It is frequently called as hot-plugging.

In software development, hot swapping is used to upgrade or update the system without interrupting the current running system. It helps us with less downtime at the time of upgrading.

OK! Stories are always good to hear. Let’s dive into the code.

Counting Real-Time Trades

In this article we start to see how to aggregate Coinbase trades in real-time, using the GenServer behaviour. We’ll build an aggregation process that groups and count the trades.

Camarero is a ready-to-use solution to add some JSON API functionality to the existing application or to implement the read-only JSON API from the scratch when more sophisticated (read: heavy) solutions are not desirable. Below is the typical picture of how Camarero is supposed to be plugged in.

It is blazingly fast.
