Code link point. Decoupling is also one of its purposes.
When you use other source code, try to encapsulate it as much as possible.
In the future, you can easily replace them with others
The fewer interfaces, the better.
If it has too many interfaces, it may only be used by coupling, That is your choice.
Call directly because there are too many interfaces.
This goes against the meaning of the project itself.
But viper is so great, So powerful. We don't usually give it up.
Add more source code if it like log system and config etc in the future.
// return *viper.Viper
link.Config() - Default config file position is in your project directory Here i didn't create the config file. you should create it by yourself.
example:
prject : /home/xxx/web
config : /home/xxx/web/etc/go.iniHere I encapsulate my own log system.
Maybe there will be something better and more like in the future. I can easily replace it here
link.INFO(args ...interface{})
link.DEBUG(args ...interface{})
link.WARN(args ...interface{})
link.ERROR(args ...interface{})
link.FATAL(args ...interface{})
