What is the most common approach to configure a backend app?
I guess most people are using https://github.com/spf13/viper but I don't know if I should read everything from

Could I get a code review?
Use Viper for config file or environmental variable configuration -- it's going to save you a whole lot of time.

Library for Python similar to Go's Viper / 12 Factor
I've mostly been using https://github.com/spf13/viper of late for my go projects. It supports the standard config formats, (json, yaml, toml etc) and lets you override any value with a ENV value.

Two ways to provide configuration: command-line, yaml file.
Not only that, the "unmarshall to struct" method doesn't work at all for environment variables. https://github.com/spf13/viper/issues/188
c9h

🐍 c9h (cottonmouth), a zero-config config. My first proper OSS project (which I'm treating as a learning exercise); feedback and/or contributions are greatly appreciated!
c9h (cottonmouth) is a configuration library heavily inspired by Steve Francis' Viper package for Go. It's available on NPM (c9h) and you can find it on GitHub.
If you still think there's some room for improvements to be made, please let me know (or better, open an issue)!
