I 100% understand where you are coming from, and entirely agree that good intro-level tutorials are important and valuable. There are several Elixir intros out there, such as Learn Elixir and Learn Phoenix as well as good content on Udemy … but, most are indeed language intros and don’t really go through that “big picture” view in creating an application. Design patterns, library choices, development practices …
The closest I’ve seen is Daily Drip Elixir. They do a series where the walk through the creation of Firestorm Forum, which is pretty cool.
Personally, I want to do content for people in that intermediate phase of Elixir exploration, as people need something to “graduate” to once they are comfortable with the every-day things like pattern matching and using mix .. but I’m not sure I can make the time commitment to a full episodic series covering application development and design. However, I do want to discuss design patterns and such things in the episodes, and I will eventually be organizing things into playlists … so who knows .. maybe it will organically emerge to some extent?
Enjoy your journey in Elixir .. it’s a pretty awesome toolbox with a pretty great community already around it
