    Use Viper for config file or environmental variable configuration -- it's going to save you a whole lot of time.

    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

    IDE: use whatever make you productive. I personally use vscode. VCS: git, as golang communities use github heavily as base for many libraries. AFAIK Linter: use staticcheck for linting as it looks like mostly used linting tool in go, supported by many also. In Vscode it will be recommended once you install go plugin. Libraries/Framework: actually the standard libraries already included many things you need, decent enough for your day-to-day development cycles(e.g. `net/http`). But here are things for extra: - Struct fields validator: validator - Http server lib: chi router , httprouter , fasthttp (for non standard http implementations, but fast) - Web Framework: echo , gin , fiber , beego , etc - Http client lib: most already covered by stdlib(net/http), so you rarely need extra lib for this, but if you really need some are: resty - CLI: cobra - Config: godotenv , viper - DB Drivers: sqlx , postgre , sqlite , mysql - nosql: redis , mongodb , elasticsearch - ORM: gorm , entgo , sqlc(codegen) - JS Transpiler: gopherjs - GUI: fyne - grpc: grpc - logging: zerolog - test: testify , gomock , dockertest - and many others you can find here

    Is this sufficiently better than https://github.com/spf13/viper to warrant a switch?
  • [QUESTION] - How would I Read from multiple config files and environment variables?

    I'm using https://github.com/spf13/viper for configuration manager.

    Ya, I think this issue explains one of the problems: https://github.com/spf13/viper/issues/761

  • How To Work With Multiple Go Files?
    2 projects | /r/golang | 2 Feb 2023
    There are some Go packages that can make config easy such as Viper or what I'll do in some of my quick/simple projects is to have a Config struct that I load from a JSON file. You can .gitignore the JSON file, and have your program on first startup write a default JSON file with some sensible default settings (like randomized secret keys for your cookies or JWT tokens and await only your database and email credentials to be filled in).

What are some alternatives?

When comparing golangci-lint and viper you can also consider the following projects:

godotenv - A Go port of Ruby's dotenv library (Loads environment variables from .env files)

envconfig - Small library to read your configuration from environment variables

koanf - Simple, extremely lightweight, extensible, configuration management library for Go. Support for JSON, TOML, YAML, env, command line, file, S3 etc. Alternative to viper.

ireturn - Accept Interfaces, Return Concrete Types

kelseyhightower/envconfig - Golang library for managing configuration data from environment variables

mapstructure - Go library for decoding generic map values into native Go structures and vice versa.

cleanenv - ✨Clean and minimalistic environment configuration reader for Golang

ini - Package ini provides INI file read and write functionality in Go

goConfig - goconfig uses a struct as input and populates the fields of this struct with parameters from command line, environment variables and configuration file.

gosec - Golang security checker

golangci-lint-action - Official GitHub action for golangci-lint from its authors

config - JSON or YAML configuration wrapper with convenient access methods.
