Building RESTful API with Hexagonal Architecture in Go
Instead of directly accessing environment variables with os.Getenv(), integrating a configuration handler like viper might make it maintainable.

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.

Which packages do you recommend for building cli tools?
Cobra and Viper.

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

Tools besides Go for a newbie
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

Ultimate config for Go applications
Is this sufficiently better than https://github.com/spf13/viper to warrant a switch?

https://github.com/joho/godotenv - load env file (or sometimes https://github.com/spf13/viper or load https://github.com/yosuke-furukawa/json5 directly)

Is this clear why its useful?
There is already a more complete, safer and neatly written godotenv alternative. It may be taken as an educational inspiration for next attempts.

What are some alternatives?
When comparing viper and godotenv you can also consider the following projects:
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.
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.
config - JSON or YAML configuration wrapper with convenient access methods.
go-toml - Go library for the TOML file format
env - A simple and zero-dependencies library to parse environment variables into structs
Gin - Gin is a HTTP web framework written in Go (Golang). It features a Martini-like API with much better performance -- up to 40 times faster. If you need smashing performance, get yourself some Gin.
validator - :100:Go Struct and Field validation, including Cross Field, Cross Struct, Map, Slice and Array diving
