Set environment based on environment variable

[Mehul Kar]

I can't tell from the docs/guides, but I'm looking for a way to set an environment variable on my system and Geddy defaults to that environment (instead of having to pass it in as a CLI arg).

Is this possible? E.g. Rails uses `RAILS_ENV`.

I see `GEDDY_ENVIRONMENT` in https://github.com/geddy/geddy/wiki/Debugging, but not sure how I can get `node_modules/geddy/bin/cli.js` to default to that. Do I need to write my own wrapper script?

Sorry, the wiki info is totally outdated.

Geddy's startup will look for a command-line flag, then the standard NODE_ENV, before falling back to the base config:
