Notes on learning Elixir and Phoenix

Notes on learning Elixir and Phoenix

Just some assorted notes I've made while digging into Phoenix, Elixir and friends. I'm coming from a strong Rails background, so many of these will refer to features from that framework.

Views / Templates

Biggest difference from Rails?

Unlike Rails, where rendering is almost always performed by a template file, the responsibility of rendering a response in Phoenix lies with a view module (that typically corresponds to the current controller module.) This view module will typically offer a whole bunch of render functions (matching different parameters, first and foremost the template name.) Templates (found in web/templates/) will directly compile into such functions.
