Passing environment-dependent variables in webpack

Question

You can directly use the EnvironmentPlugin available in webpack to have access to any environment variable during the transpilation.

You just have to declare the plugin in your webpack.config.js file:

var webpack = require('webpack');

module.exports = {
    /* ... */
    plugins = [
        new webpack.EnvironmentPlugin(['NODE_ENV'])
    ]
};

Note that you must declare explicitly the name of the environment variables you want to use.
