lingui extract doesn't set NODE_ENV required by babel-preset-react-app

When I run ‘lingui extract’ I receve this message error:

Error: Using babel-preset-react-apprequires that you specifyNODE_ENVorBABEL_ENV environment variables. Valid values are "development", "test", and "production". Instead, received: undefined.

‘lingui extract’ work only with this setup: ‘NODE_ENV=production lingui extract’

Is it a bug? What’s the problem?

Create React App uses development env for everything except for build. Ideally we should handle this without a warning, because CRA handles it under the hood without user’s interference.

I’m trying to come up with scenario, when extracting messages in development env would be harmful (or in production)… It seems that for our usecase (extracting messages from source), there’s no difference. Setting env to production might be after all safer option.

Ideas welcome!

I want to close this with upcoming 3.0 release, which will have better support for CRA.

Update: The env will be set to development after all.

I’m working on new version of plugins/macros and in production mode they will remove all unnecessary attributes, like description and defaults. These attributes are used only offline (either in message catalogs as a hint for translators or during compile), but they aren’t needed in production.
