Example

if you use event emitter, I prepared MicroEmitter for this. Recommnd: MicroEmitter

import MicroStore from 'micro-store';
import { EventEmitter } from 'events';
 
let AppDispatcher = new EventEmitter(); // singleton
 
class TodoStore extends MicroStore {
  constructor() {
    super();
    this.defaults = {
      text: '',
      completed: false,
    };
    this.register(AppDispatcher, {
      'TODO_CREATE': (payload) => {
        this.create(payload.entity);
      },
      'TODO_UPDATE': (payload) => {
        this.update(payload.id, payload.updates);
      },
      'TODO_DESTROY': (payload) => {
        this.destroy(payload.id);
      },
    });
  }
}
export default new TodoStore();
 
class TodoItemComponent {
  constructor() {
    this.todos = TodoStore.get();
 
    // when TodoStore updated, call this.
    TodoStore.addChangeListener(this.render());
 
    // when TodoStore emit custom event(ex: PASS_VALIDATION), call this.
    TodoStore.addCustomEventListener('PASS_VALIDATION', this.fetch());
  }
  componentDidMount() {
    const isCreatModalShowing = TodoStore.getData('isCreatModalShowing');
    if (isCreatModalShowing) this.someaction();
  }
  /* ... */
  onClick() {
    TodoStore.setData('isCreatModalShowing', true);
 
    // if you don't use actions or dispatcher
    TodoStore.create({ text: 'Hello MicroStore' });
 
    // if you use action or dispatcher
    AppDispatcher.emit('TODO_CREATE', { text: 'Hello MicroStore' });
  }
}
TodoStore.get(); // get all data
TodoStore.get(id); // get an item
TodoStore.order('text').get();
TodoStore.order('text', true).get(); // reverse
TodoStore.where({ completed: true }).get();
TodoStore.limit(3).get();
TodoStore.where({ completed: true }).order('text').limit(5).get();
