Here's a tiny, but fully functional (ha) incremental game framework. Some notes:

• Built with CoffeeScript. I like CoffeeScript very much.
• Inspired by Elm, minus the types, obviously.
• Uses Inferno.js as its rendering layer. It's extremely fast.
• main.coffee dispatches to a state object, because games typically employ finite state machines. With a single state, this is unneccessary, of course.

This is a RESTful Rails controller, implementing all 7 RESTful actions. In my Rails apps, 9 out of 10 controllers will end up looking like this.

class PostsController < ApplicationController
  load_and_authorize_resource

  def create
    @post.save and redirect_to(@post) or render(:new)
  end

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.
