import { observable } from 'mobx';
import crossTab from 'mobx-crosstab';

const store = observable.deep({ count: 0 });
crossTab('count', store);

import { observable } from 'mobx';
import crossTab from 'mobx-crosstab';

class TodoStore {
  todos = crossTab('todos', []);
}

import { observable } from 'mobx';
import crossTab from 'mobx-crosstab';

class TodoStore {
  @crossTab('todos')
  @observable
  todos = [];

import { observable } from 'mobx';
import crossTab from 'mobx-crosstab';

class TodoStore {
  @crossTab
