My JSON structure is like this

this pkg can help you convert JSON to a class instance. https://www.npmjs.com/package/class-converter

import { property, toClass } from 'class-convert';

class UserModel {
  @property('i')
  id: number;

  @property()
  name: string;
}

const userRaw = {
  i: 1234,
  name: 'name',
};

// use toClass to convert plain object to class
const userModel = toClass(userRaw, UserModel);
// you will get a class, just like below one
{
  id: 1234,
  name: 'name',
}
