What problem are you trying to solve?

I need to configure logging for my app and I need to differentiate whether a message originated from a prod environment or from one of the preview environments.

Describe the solution you'd like

Something akin to checking an ENV var that updates as the status of the Deno isolate/instance changes

Describe alternatives you've considered

Tracing the URL of requests that generate messages as a proxy for this info

Documentation, Adoption, Migration Strategy
