Environment Variables Duplication

[rwieruch]

I think there is no way around defining env variables twice with Next.js in next.config.js and .env file. In the future, it should be possible to define these only in an .env file though.

If you use the package dotenv-webpack instead of dotenv, you don't need to have them in next.config.js.

Oh, really? Didn't know about this. Maybe someone can create a PR for it.
