This allows in some case when you use other modules that use this source-map-support lib to get only a single version at the root of node_modules. For example, this can prevent issues when requiring using webpack Banner plugin (compiled code is not always requiring dependencies as you would expect).
babel-register
The require hook will bind itself to node's require and automatically compile files on the fly.
Install
$ npm install babel-register
Usage
require("babel-register");
All subsequent files required by node with the extensions .es6, .es, .jsx and .js will be transformed by Babel.
See documentation for details.
