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!
