Generates an elm app inside a Phoenix (1.3) app with the necessary scaffolding

adds:

• elm files (Main, Types, State, View)
• an embed script
• elm-package.json
• A phoenix controller, view and template
• an elm-test setup

to run the generator:

> mix phx.gen.elm

then follow post install instructions:

1. add the following to the plugins section of your brunch-config.js

   elmBrunch: {
     elmFolder: '.',
     mainModules: ['elm/Main.elm'],
     outputFile: 'elm.js',
     outputFolder: '../assets/js',
     makeParameters: ['--debug'] // optional debugger for development
   }

2. add elm to the watched array in your brunch-config.js You may also want to add /elm\.js/ to the babel ignore pattern to speed up compilation

   babel: {
     ignore: [/vendor/, /elm.js/]
   }

3. in your app.js file add the following

   import ElmApp from './elm.js'
   import elmEmbed from './elm-embed.js'
   
   elmEmbed.init(ElmApp)

4. and finally in your router.ex file add

   get "/path-to-elm-app", ElmController, :index
