MessagePack

MessagePack encoding for Go

Efficient

msgpack is a drop-in replacement for encoding/json package that can be up to 5 times faster.

Customizable

Use custom encoders and decoders to customize serialization for user-defined and stdlib types.

Extensible

Extend MessagePack by providing type-aware encoding for your types using ext format family.

import "github.com/vmihailenco/msgpack/v5"

type Item struct {
    Foo string
}

func main() {
    b, err := msgpack.Marshal(&Item{Foo: "bar"})
    if err != nil {
        panic(err)
    }

    var item Item
    err = msgpack.Unmarshal(b, &item)
    if err != nil {
        panic(err)
    }
    fmt.Println(item.Foo)
    // Output: bar
}
