PeterAndCode: YouTube tutorials about all things Elixir
For 2021, I decided to start a YouTube channel about coding with Elixir! Hurray!
I learn best by teaching others, which is why I “challenged” myself to starting the YouTube Channel PeterAndCode (super creative name, I know
). The idea is to collect my experiences and learnings as an Elixir developer and channel them into relatively short (up to 20-25min, but preferably shorter) YouTube videos. This way, I hope to get a better grasp of Elixir topics all while generating (hopefully) useful content for you, my fellow Elixir enthusiasts, and the general software development community ![]()
On that channel, I plan on covering a range of topics like:
- Elixir libraries that I’m using
- common coding practices that I’ve learned (like the “Clean Code” principles)
- software architecture and design learnings (like the Hexagonal/Onion architecture)
- some general Elixir topics as well (like protocols vs behaviours and ETS tables)
If you have a topic, which you would like to see covered, please post it in this thread and I will take a look at it ![]()
I published my very first video today, which is about encrypting your data with Cloak Ecto, a very useful library which I recently discovered. I hope you like it and would appreciate your feedback very much! ![]()

I just published a 2-Part series about the Hexagonal and Onion Architectures and their combination, the Explicit Architecture. Part 1 is an introduction to the architectures and Part 2 shows an implementation of the Explicit Architecture in Elixir. Feedback is much appreciated!

I just published another video which focuses on how to get started when designing the architecture of a new system. It’s not Elixir related though (I’m sorry), but the next videos will be again
I hope you can enjoy it nevertheless.

Just watched the video on Cloak.Ecto. Very helpful and nicely paced. Thanks!

For Cybersecurity Awareness Month I “hacked” a Phoenix LiveView app by “decoding the HTML code” and editing web socket messages with Burp Suite. Don’t trust anything your LV receives.

Thanks for that first video! I am looking forward to the next videos you publish.
