Good day for all readers!
I have api service which needs key for some decrypt issues. Key calculates all time when I make request. That is wrong from an architectural point of view.
The option with environments (.env, viper…) drops because, in the future, I want to bring out this module to a separate library.
Hint me, how it is possible without using environments to calculate the key when starting the application and use it until stopping the application?
A global var starts with a capital, so it is reachable from within other packages.
But… it’s actually bad behaviour, because those other packages can change it.
Having a non capital one, still means that functions in the same package can change it.
Perhaps you can use a constant?
or make a singleton variable, see :
