babel-preset-es2015-loose

Babel preset that uses modify-babel-preset to modify babel-preset-es2015 and enable loose mode for classes and modules

Install

Install both this preset, and the core 'babel-preset-es2015' that it modifies:

$ npm install --save-dev babel-preset-es2015-loose-classes-and-modules babel-preset-es2015

Why do you need to install both? The idea is that babel-preset-es2015-loose-classes-and-modules will always be up to date because it will always use the version of babel-preset-2015 that you have installed. If you don't want to update to the latest Babel release - you don't have to. Just pin babel-preset-2015 to the version you need.
