Inline values from a JSON file eg. a config file

Does not work if the argument to require() is an identifier or a template literal

config.json:

{
  "foo": "bar"
}

In

var foo = require('config').foo;

Out

var foo = "bar";

$ npm install babel-plugin-inline-json --save-dev

.babelrc

{
  "plugins": [["inline-json", {"matchPattern": "config"}]]
}

$ babel --plugins inline-json script.js

require("babel-core").transform("code", {
  "plugins": [["inline-json", {"matchPattern": "config"}]]
});

this is based on @mwilliams-change's babel-plugin-inline-json-config-values.
