Use ES6 in Rails everywhere

ES6 (EcmaScript 2015) adapter for Rails. It transpiles all ES6 code to ES5 (JavaScript) using ruby-babel-transpiler.

• assets (supported extensions: .es6, .es6.js)
• views as remote es6 script. (supported extensions: .es6)
• views as inline html

es6-rails-example

Assets:

• add ES6 code as .es6 or .es6.js files in /app/assets/javascripts/
• or use rails generator: rails g es6:assets my_file

ES6 views:

• add ES6 code as .es6 files in /app/views/ (you can include erb code too)

HTML views:

• add ES6 code in any HTML(ERB) file in /app/views/ using: <%= es6_transform do %> .. es6 code .. <% end %>

E.g.:

<script>
  <%= es6_transform do %>
    let square = x => x * x;
    console.log(square(5));
  <% end %>
</script>
