Technical requirements

In this chapter, you'll see some code examples using Go. I recommend that you install Go and try to build and run the code examples yourself.

Installing Go with Homebrew on macOS

On macOS, I recommend using Homebrew:

$ brew install go

Next, make sure the go command is available:

$ ls -la `which go`
lrwxr-xr-x  1 gigi.sayfan  admin  26 Nov 17 09:03 /usr/local/bin/go -> ../Cellar/go/1.11.2/bin/go

To see all the options, just type go. Also, make sure that you define GOPATH in your .bashrc file and add $GOPATH/bin to your path.

Go comes with the Go CLI that provides many capabilities, but you may want to install additional tools. Check out https://awesome-go.com/.
