JSON serialize and deserialize using go generics

jsonconvert.go

package jsonconvert

import "encoding/json"

func Deserialize[T any](str string) (T, error) {
	var d T
	err := json.Unmarshal([]byte(str), &d)
	if err != nil {
		return d, err
	}
	return d, nil
}

func Serialize(obj any) (string, error) {
	d, err := json.Marshal(obj)
	if err != nil {
		return "", err
	}
	return string(d), nil
}

func main() {

	data := `{"id": 1001, "name": "Laptop"}`

	product, err := jsonconvert.Deserialize[Product](data)
	if err != nil {
		log.Println(err)
	}
	log.Println(product)

	str, err := jsonconvert.Serialize(product)
	if err != nil {
		log.Println(err)
	}
	log.Println(str)
}

Output

{1001 Laptop}
{"id":1001,"name":"Laptop"}
