Angular compilation problem

[Nicola Taddei]

In angular compilation NODE_ENV is undefined with this configuration.
I have my own webpack to extend basic configuration

Angular script:

"build:prod": "cross-env NODE_ENV=prod && ng build --prod"

webpack.config.js:

...process.env.NODE_ENV === 'prod'
              ? [purgecss]
              : []

My bad,
I should have removed "&&"
