Using local Go package path

A bunch of times you might find yourself working with private Go packages that need to be tested locally. Go let's us do that with replace in go.mod file

module mymodule

go 1.17

# make sure replace is just after require
require github.com/org/repo v1.1.2
replace github.com/org/repo => /Users/PC/Documents/repo

require (
        ...
        ...
)

After this, just run go get -u . and restart your IDE for changes to make effect
