babel-preset-es2015-node4-loose

> Babel preset that uses [modify-babel-preset] to modify [babel-preset-es2015-node4]
and enable [loose mode] where available.


Install

Install both this preset, and the core 'babel-preset-es2015-node4' that it modifies:

``sh
$ npm install --save-dev babel-preset-es2015-node4-loose babel-preset-es2015-node4
`

Why do you need to install both? The idea is that babel-preset-es2015-node4-loose
will always be up to date because it will always use the version of
babel-preset-2015-node4 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.

Usage

$3

.babelrc

`json
{
"presets": ["es2015-node4-loose"]
}
`

$3

`sh
$ babel script.js --presets es2015-loose-loose
`

$3

`javascript
require("babel-core").transform("code", {
presets: ["es2015-loose-loose"]
})
`

Does not include regenerator!

[babel-preset-es2015-node4] doesn't include regenerator as mentioned here.

If you need it you will have to npm install and include regenerator yourself:

`json
{
"presets": ["es2015-node4-loose"],
"plugins": ["transform-regenerator"]
}
``

Note: Regenerator doesn't have a loose mode.

About

This project has been highly inspired by [babel-preset-es2015-loose]. It will probably become obsolete when Babel team will support passing options to presets.
