ToMap

func ToMap[T any](structInstance T, structTags ...string) map[string]any

ToMap takes a struct and converts it to into an instance of map[string]any.

package main

import (
    "fmt"
    "reflect"

    "github.com/Goldziher/go-utils/structutils"
)

type Person struct {
    FirstName string
    LastName  string
    Age       int `myTag:"myValue"`
}

func main() {
    personInstance := Person{
        FirstName: "Moishe",
        LastName:  "Zuchmir",
        Age:       100,
    }

    personMap := structutils.ToMap(personInstance)

    fmt.Print(personMap)
    // { "FirstName": "Moishe", "LastName": "Zuchmir", "Age": 100 }
}

You can also pass in struct tags as an optional argument:

package main

import (
    "fmt"
    "reflect"

    "github.com/Goldziher/go-utils/structutils"
)

type Person struct {
    FirstName string
    LastName  string
    Age       int `myTag:"myValue"`
}

func main() {
    personInstance := Person{
        FirstName: "Moishe",
        LastName:  "Zuchmir",
        Age:       100,
    }

    personMap := structutils.ToMap(personInstance, "myTag")

    fmt.Print(personMap)
    // { "FirstName": "Moishe", "LastName": "Zuchmir", "myTag": 100 }
}

To omit a value, use the standard "-" struct tag value:

package main

import (
    "fmt"
    "reflect"

    "github.com/Goldziher/go-utils/structutils"
)

type Person struct {
    FirstName string
    LastName  string
    Age       int `myTag:"-"`
}

func main() {
    personInstance := Person{
        FirstName: "Moishe",
        LastName:  "Zuchmir",
        Age:       100,
    }

    personMap := structutils.ToMap(personInstance, "myTag")

    fmt.Print(personMap)
    // { "FirstName": "Moishe", "LastName": "Zuchmir" }
}
