Environment Variables
REACT_GLOBAL_STATE_DEBUG
The REACT_GLOBAL_STATE_DEBUG variable can be set to any truthy value in Node
environment (or injected into the client-side bundle using the Webpack's
EnvironmentPlugin)
to enable debug logging by react-global-state library. In either case
the logging is enabled for non-production code only, which is tested by
process.env.NODE_ENV
value being distinct from "production".
