40: Mental Models for Elixir and LiveView

40 minutes

We talk about the mental models we use for writing our Elixir code and for thinking about our Elixir systems (starting at 5:46). We cover transformations, plug, and Mark's "Workshop Model" (starting at 23:45). We also talk about LiveView, (starting at 31:20) how we approach it today, mistakes we've both made and seen. A fun discussion! We want to continue the discussion with you over on ElixirForum. Check the show notes for links to those topics!

Mental models coming to Elixir

Phoenix pipelines and reconstructing plug

https://pragmaticstudio.com/courses/elixir – The PragProg course Cade mentioned

It's all about data transformations

Code organization and namespace design discussion

Mark's mental model of the "The Workshop" starting at 23:45

Modules are binders of instructions

Refactoring, namespace design, code organization is about getting your workshop organized.

LiveView, anti-patterns, making the mental shifts

The "Lift and shift" approach doesn't work well coming from OOP or React to Elixir

Live View components and passing left over arguments to the HTML makes it cleaner and easier
