buptbill220 / json2struct

translate json data to golang sturct and other language models

json2struct generates strongly-typed models and serializers from JSON, making it a breeze to work with JSON type-safely in any other languages.

Supported Inputs

JSON	JSON FILE

TypeScript	GraphQL queries

Target Models

Golang	Protobuf

Features

• written by golang
• comparing with , it can distinguish golang map model.

json data for example:
{
        "23": 343434,
        "3232": 23
}
the result translated by `json-to-go`
type AutoGenerated struct {
        Num23   int `json:"23"`
        Num3232 int `json:"3232"`
}

we expect result in follow
type AutoGenerated map[int]int

• comparing with , it identifys int/int64/float model more precise. Apart from this, json2struct generates single type name for embedding struct model if there are 2 or more json input.

json data
{
  "aid": 6858121093648023822,
  "bid": 6858073458614731015,
  "show_more": true,
  "coupon": {
    "6858121093648023822": {
      "max_coupon": {
        "credit": 8
      },
      "total_stock": 2
    }
  }
}
`quicktype` result
type Welcome struct {
        AID      *float64        `json:"aid,omitempty"`
        BID      *float64        `json:"bid,omitempty"`
        ShowMore *bool     `json:"show_more,omitempty"`
        MaxCouponDefault   map[string] Coupon `json:"coupon,omitempty"`
}
type Coupon struct {
        MaxCoupon  *MaxCoupon `json:"max_coupon,omitempty"`
        TotalStock *int64     `json:"total_stock,omitempty"`
}
type MaxCoupon struct {
        Credit *int64 `json:"credit,omitempty"`
}

we expect
type Welcome struct {
        ShareComboID        *int64                    `json:"share_combo_id,omitempty"`
        AddressComboID      *int64                    `json:"address_combo_id,omitempty"`
        ShowMoreTalentAreas *bool                       `json:"show_more_talent_areas,omitempty"`
        ShowMoreBrandAreas  *bool                       `json:"show_more_brand_areas,omitempty"`
        MaxCouponDefault    map[int64]MaxCouponDefault `json:"max_coupon_default,omitempty"`
}
for more, if we translate the following json to the same go file, the model `Coupon、MaxCoupon` will be double definition.
{
    "coupon": {
    "6858121093648023822": {
      "max_coupon": {
        "credit": 818
      },
      "total_stock": 2000
    }
}

• make it protobuf defination

Installation

go get github.com/buptbill220/json2struct/json2struct

Using json2struct

• for sdk lib

import "github.com/buptbill220/json2struct"

ret, err := Json2Struct("auto_name", `[1,2,3,44444444444]`, GoStructType)
fmt.Printf("ret:\n %s, %v\n", ret, err)

• for installed cmd json2struct gen --json [1,2,3] [--file a.json] [--type go]
