What is the most common approach to configure a backend app?

1. viper

   1 79 28,800 8.1 Go

   Go configuration with fangs

   

   I guess most people are using https://github.com/spf13/viper but I don't know if I should read everything from

2. InfluxDB

3. kelseyhightower/envconfig

   2 15 5,253 2.3 Go

   Golang library for managing configuration data from environment variables

   

   - Having one way of configuring the app is excellent. You can either prefer environment variables, a file, or flags. You can do what Viper does by reading the file and unmarshalling it. The built-in flag package is enough for your flag-based config needs. If you want to prefer environment variables, I prefer https://github.com/kelseyhightower/envconfig

4. ko

   3 32 8,055 8.8 Go

   Build and deploy Go applications

   

   - There're many resources available about containerizing an application, but I suggest you buildpacks or ko, which doesn't require writing a Dockerfile

5. ff

   4 7 1,401 3.3 Go

   Flags-first package for configuration

   

   We have been using https://github.com/peterbourgon/ff for long time now. It combines the standard flags with the environment variables nicely.
