App Bridge Modal vs EASDK Modal

app-bridge-vs-easdk-modal.js

import {Modal} from '@shopify/app-bridge/actions';

const modalOptions = {
  title: 'My Modal',
  message: 'Hello world!',
};

const closeModalCallback = function() {
  console.log('Modal was closed!');
}

// EASDK - create modal, attach callback, open modal, all in one call:
// ShopifyApp.Modal.alert(modalOptions, closeModalCallback);

// App Bridge - broken down into smaller steps:
const myModal = Modal.create(app, modalOptions); // create modal
myModal.subscribe(Modal.Action.CLOSE, closeModalCallback); // attach callback
myModal.dispatch(Modal.Action.OPEN); // open modal
myModal.set({title: 'My New Modal'}); // update title
