'How to create nested DTO class in NestJS corresponding to Schema

I am new to NestJs and trying to create nested schema in Mongoose as I want this data structure in my database:

{
  name:"John",
   age:28,
  address:{
     city:"Delhi",
     state:"Delhi
  }
}

For this I have created below mongoose schema:

user.schema.ts

import mongoose from "mongoose";

export const UserSchema = new mongoose.Schema({

 name:{type:String},
 age:{type:Number},
 address:{
     city:{type:String},
     state:{type:String}
  }
});

How Can I write Dto class for this schema.Someone let me know As I want to add data inside database.

You can simply create two DTO classes in the following way.

export class AdressDto {
    readonly city: string;
    readonly state: string;
}
export class UserDto {
    readonly name: string;
    readonly age: number;
    readonly address: AdressDto
}

In the official Nestjs documentation you can find how to use DTO in your controllers, and you can also find how to use validators if you want to use them.
