What I did:
- add dependencies using
adopt-dev-deps topcoder-react-utils
- use production webpack config
topcoder-react-utils/config/webpack/app-production
- getting error
Cannot find module 'postcss-scss'
Probably dependency postcss-scss can to be moved from https://github.com/topcoder-platform/community-app/blob/develop/package.json#L68 to topcoder-react-utils.
