The idea behind the example

This example shows the most basic idea of babel replacement from multiple environment. We have 1 env variable: TEST which will be replaced in development env and in production env with different babel plugin. In local development, babel reads .env file and replace process.env.* in your nextjs files. In production env (such as heroku), babel reads the ENV and replace process.env.* in your nextjs files. Thus no more needed to commit your secrets anymore.

Of course, please put .env* in your .gitignore when using this example locally.
