```go

package main

import (

    "github.com/gookit/di"

)

func main() {

    box := di.New("my-services")

    

    // add a simple value

    box.Set("service1", "val1")

    

    // register a callback func.

    box.Set("service2", func() (interface, error) {

    	return &MyApp{}, nil

    })

    

    // register a factory func.

    box.Set("service3", func() (interface, error) {

    	return &MyObject{}, nil

    }, true)

    

    // get 

    v1 := box.Get("service1") // "val1"

    

    // is a singleton value. Notice: v2 == v3

    v2 := box.Get("service2").(*MyApp)

    v3 := box.Get("service2").(*MyApp)

    

    // is factory func. Notice: v4 != v5

    v4 := box.Get("service3").(*MyObject)

    v5 := box.Get("service3").(*MyObject)

}

```
