Redux-ORM nested data normalization

redux-orm-normalization.js

import {fk, many, Model} from 'redux-orm';

class Book extends Model {
    static get fields() {
        authors: many('Author', 'books'),
        publisher: fk('Publisher', 'books'),
    }
    
    static parse(data) {
      /*
      I call SomeModel.parse(jsonData), and that Model class should know what relational fields it has and 
      call AnotherModel.parse() appropriately on down the chain. Each parse method should eventually call the 
      static Model.create() method with the JSON data for that instance. That queues up all the Redux-ORM 
      creation behavior , and afterwards  you call session.reduce() to produce the updated entities "tables"
