MessagePack Response

Learn how to send MessagePack responses in Iris.

Basic MessagePack Response

package main

import "github.com/kataras/iris/v12"

type User struct {
    ID    int    `msgpack:"id"`
    Name  string `msgpack:"name"`
    Email string `msgpack:"email"`
}

func main() {
    app := iris.New()

    app.Get("/msgpack", func(ctx iris.Context) {
        user := User{
            ID:    1,
            Name:  "John Doe",
            Email: "john@example.com",
        }

        ctx.MessagePack(user)
    })

    app.Listen(":8080")
}

Custom MessagePack Encoding

app.Get("/custom", func(ctx iris.Context) {
    data := map[string]interface{}{
        "name": "John",
        "age":  25,
        "address": map[string]string{
            "street": "123 Main St",
            "city":   "New York",
        },
    }

    ctx.MessagePack(data)
})

MessagePack Collection

type Users struct {
    Users []User `msgpack:"users"`
}

app.Get("/users", func(ctx iris.Context) {
    users := Users{
        Users: []User{
            {ID: 1, Name: "John"},
            {ID: 2, Name: "Jane"},
        },
    }

    ctx.MessagePack(users)
})

Best Practices

1. Structure:

   • Validate output

2. Performance:

   • Enable compression
   • Cache responses
   • Optimize size
   • Monitor encoding
   • Handle timeouts

3. Security:

   • Validate input
   • Set headers
   • Handle errors
   • Monitor usage
   • Control access

4. Maintenance:

   • Document format
   • Update structure
   • Monitor changes
   • Regular testing
