Setting default values if not present in environment

[JoeAlamo]

Are you able to set default values for the environment variables if they are not present in your environment already, like in Bash?

Or do you recommend we handle this within our code?

I'm not sure I understand.

If setting in .env file that will become your default value.

But otherwise, if they are not set there or already on your machine, then yes, you will need your code to conditionally generate a default value.

The suggestion is to allow the syntax WEB_PROXY_PORT=${PORT:-3000}, to set WEB_PROXY_PORT to PORT if it's already defined, otherwise to 3000. Does that make sense?
