Golang : How to deal with configuration data?

Tags : golang configuration parameters

A friend ask what are the ways to deal with configuration data in Golang. Couple of ways that I can think up are :

  1. The simplest. Read configuration data from key-value pair file. See example on Golang Key-Pair value file.

  2. Read data from YAML file with goyaml.

  3. TOML - see https://github.com/BurntSushi/toml

  4. Read from environment variables.

  5. Hard code into the program source code. Which is not advisable..but if you're writing a small program or microservice..then it is ok. It will make life easier for future maintenance.


  1. Thanks to Mark for pointing out the Viper package. https://github.com/spf13/viper. From the Viper's documentation - "When building a modern application, you don’t want to worry about configuration file formats; you want to focus on building awesome software. Viper is here to help with that."
