next.js/examples/with-dotenv/next.config.js
HaNdTriX d3f1fa630e Rewrite with-dotenv example (#4924)
## Issue

I decided to rewrite the [with-dotenv](https://github.com/zeit/next.js/tree/canary/examples/with-dotenv) using [dotenv-webpack](https://github.com/mrsteele/dotenv-webpack) example because:

- changes doesn't get applied  (#4748, brysgo/babel-plugin-inline-dotenv#13)
- the production mode doesn't work at all
- this approach has already been used in the [examples/relay-modern](9320d9f006/examples/with-relay-modern/next.config.js)
- it is [documented](https://webpack.js.org/plugins/environment-plugin/#dotenvplugin) by webpack

## Alternatives

* remove/deprecate example
* fix babel-plugin-inline-dotenv
