Access environment variable

[lorrod]

Hello!
Could you please help to solve the issue with getting environment variable?
I have tried to access via:

process.env.VARIABLE_NAME

but it seems that webpack is not configured to pass process variable, am I right? I am getting Can't find variable: process

Also I have tried to pass environment variable using web pack with no luck:

new webpack.DefinePlugin({
  'process.env.API_BASE_URL': JSON.stringify('https://api.example.com'),
})

Hello. Let me think about correct way to pass user variables. It's a nice feature.
