How to pass global variables between package?

Question

go

Hello!
Actually, there is an application that will serve the rest of the front using gin.
The application has a configuration that is declared and read in the package main.
How can I correctly transfer this configuration to the package that will store the handlers directly?
Well, in general, thanks in advance for any comments on the code :-)

Anything with a capital letter is exported from the package.
Nothing more needs to be done.
