## The idea behind the example

This example show how to set custom environment variables for your application based on NODE_ENV using [transform-define](https://github.com/FormidableLabs/babel-plugin-transform-define).

## Caveats

Because a babel plugin is used the output is cached in `node_modules/.cache` by `babel-loader`. When modifying the configuration you will have to manually clear this cache to make changes visible.
