RubyEs6ModuleTranspiler

ES6 Module Transpiler Ruby Gem, a handy little gem to help convert your ES6 code into CommonJS, AMD or YUI formats using Square's ES6 Module Transpiler.

Installation

Add this line to your application's Gemfile:

gem 'ruby_es6_module_transpiler'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ruby_es6_module_transpiler

Usage

Note that Node.js is required for the transpiling.

Add the necessary require to the file in which the gem is needed

require 'ruby_es6_module_transpiler'

Call transpile with ES6 code. By default, it will transpile to AMD. For example, calling

js_code = <<-JS
import { get, set } from 'ember';
JS

RubyES6ModuleTranspiler.transpile(js_code)

will return

define(
["ember"],
function(__dependency1__) {
  "use strict";
  var get = __dependency1__.get;
  var set = __dependency1__.set;
});

You can also add in extra options like so:

js_code = <<-JS
import { get, set } from 'ember';
JS

RubyES6ModuleTranspiler.transpile(js_code, { type: "Globals", global: "renamed"})

which returns

(function(__dependency1__) {
  "use strict";
  var get = __dependency1__.get;
  var set = __dependency1__.set;
})(renamed.ember);

Check out Square's ES6 Module Transpiler for more info on the various options available.
