    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

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 - ‚ú®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
