💬 Tl;dr

Code:

import { Vicis } from "vicis";
const configuration = {
  cast: {
    // convert `_id` to integer
    _id: Vicis.INTEGER,
    // convert `registered` to boolean
    registered: Vicis.FLAG,
  },
  nullish: {
    // if not set `confirmed` set to `false`
    confirmed: false,
  },
  exclude: [
    // exclude fields with names like `password`
    /(?:password)/gi, /^(?:_)(?:_)?/,
  ],
  omit: [
    // remove fields that may be personal
    "createdAt", "updatedAt", "deletedAt",
  ],
  rename: {
    // rename `_id` to `id`
    _id: "id",
    // rename `email` to `login`
    email: "login",
  },
  replace: {
    // always replace field value with `null`
    url: null,
  },
  order: [
    // `id` and `login` goes first, then everyone else
    "id", "login",
  ],
};
const model = {
  _id: "54759309034942804",
  email: "johnwick@gmail.com",
  userPassword: "36e80092ff7f1ed72903cda9409b9d2c",
  registered: "1",
  url: "example.com",
  createdAt: "2020-01-01 01:23:45",
  __v: 1
};
const serializer = new Vicis(configuration);
serializer.data(model);
console.log(serializer.getData());

Output:

{
  "id": 54759309034942800,
  "login": "johnwick@gmail.com",
  "confirmed": false,
  "registered": true,
  "url": null
}
