{..., loader: 'jsx-loader?harmony&es6module'}You must install react-tools as a
peer dependency, ideally pegged to the same version of React that you use at runtime.
To enable ES6 features, use ?harmony and/or ?es6module in your loader config.
Flow-style type annotations can be stripped using ?stripTypes.
In general, any flag that react-tools's transform options parameter will
accept may be provided as a query parameter to this loader.
This fork has been updated to apply source maps from previous loaders to the source map output by
react-tools.
