Groxio is building a series targeted to beginner and intermediate Elixir developers at Quadblock- Elixir/LiveView videos. The first seven are free, and the rest will go for 10 bucks. The proceeds will go to fund coding diversity mentoring programs. I would love comments on the approaches, as I’ll use the same approach in the prag book.

In general, it’s the course my mentees to through (or the first part). I seem to have success teaching these concepts:

• Understand pattern matching first
• Organize modules into like concepts around DATA
• Organize code around the data concepts, with as many reducers over that type as possible
• Write tests as pipelines

Then, the LiveView discussion becomes easy:

• In LiveView, build a static screen first, with hardcoded data in mount
• Change the hardcoded data as your functions later will to flesh out your render
• If needed, extract render-text text into views

And next:

• Replace hardcoded mount with dynamic content (your true model)
• Change the data with handle_event and handle_info
• Keep the handle-callbacks skinny. If necessary have adapter functions in the Live module

Finally:

• Optimize the liveview difs, and tighten them up
• Extract common components
• Implement data rehydration concerns
• Implement pubsub concerns

Does the approach seem sound?
