babel-env

The babel-env npm package can be used to set up a consistent environment
for projects using Babel and running on node.js version 6 (at least).

 npm install --save-dev babel-env

This will install all useful Babel packages and create a default .babelrc
file in the project root. The .babelrc file will automatically be updated
when updates of babel-env are installed.

See also babel-env-test for
an example of how babel-env is used.

Prevent automatic .babelrc overwrite

If you do not want your .babelrc to be overwritten by babel-env, add
a comment containing babel-env-disable, such as:

 // babel-env-disable
{
  "presets": [
    "es2015"
  ],
  "plugins": [
    "transform-es3-property-literals",
    "transform-es3-member-expression-literals"
  ]
}
