Overview

JSON Marshalling Go → JSON

JSON marshalling means generating a JSON representation from a Go object. It is done with json.Marshal(). The result is a byte array. To convert the byte array to a string, see:

Go Integers | Conversion between bytes and strings

Map Marshalling

Struct Marshalling

By default, only fields that start with capital letters are marshaled. The fields that start with lower caps are invisible to the marshaling process.

type Item struct {
  Color string
  Size int
  Options []string
}

i := Item{Color: "blue", Size: 5, Options: []string{"brake", "acceleration", "lights"}}

ba, err := json.Marshal(i)

fmt.Println(string(ba))
