js2go

Encode Go structs to js.Values and viceversa based on tags.

Usage

Assume we want to encode/decode a struct defined as follows:

type config struct {
	StringField  string   `js:"stringField"`
	IntegerField int      `js:"integerField"`
	StringsArray []string `js:"stringsArray"`
	NestedObject struct {
		InnerStringField  string   `js:"innerStringField"`
		InnerIntegerField int      `js:"innerIntegerField"`
		InnerStringsArray []string `js:"innerStringsArray"`
	} `js:"nestedObject"`
}

Decode a js.Value onto a Go struct

var c config
err := js2go.Decode(val, &c)
if err != nil {
    // handle error
}

Encode a Go struct as a js.Value:

jsValue, err := js2go.Encode(&config{
    StringField:  "hello world",
    IntegerField: 1234,
    StringsArray: []string{"hello", "world"},
})
if err != nil {
    // handle error
}
