Ruby Babel is a bridge to the JS Babel transpiler.
require 'babel/transpiler'
Babel::Transpiler.transform File.read("foo.es6")
$ gem install babel-transpiler
This library depends on the babel-source
gem which is updated any time a new version of Babel is released.
The ExecJS library is used to automatically choose the best JavaScript engine for your platform. Check out its README for a complete list of supported engines.
