Go uses a small number of environment variables to configure builds, modules.
Modules are explicit/sealed off, there isn't much of a case for tools like nix unless you're using extensions or alternative compilers.
Documentation
environment variables https://pkg.go.dev/cmd/go#hdr-Environment_variables
Locations
~/.config/go/env'go env' set environment variables
Environment Variables
A small subset of useful environment variables.
GOPATH= GOBIN=~/go/bin # where go installed executables should go GOPROXY=private/privacy options
# packages that should not be indexed publicly # (reused by GONOPROXY, GONOSUMDB if they are not set) GOPRIVATE=*.corp.example.com,rsc.io/private GONOPROXY=*.corp.example.com,rsc.io/private GONOSUMDB=*.corp.example.com,rsc.io/private
Go Env
go envlets you set/persist go environment variables.
They will be loaded in new shells automatically.go env -w GOBIN=/foo/bar/bin # set default envvar val within environment go env -u GOBIN # unset environment variable set by 'go env'
