Store

Global Store, unified management of all variables

• get(key)
• set(key, value)
• on(key, callback, force), when force is true, callback will be called immediately when initializing
• off(key, callback)

example

// Framework
import { store } from '@ice/stark-data';

const userInfo = { name: 'Tom', age: 18 };
store.set('user', userInfo); // set UserInfo
store.set('language', 'CH');

// Sub-application A
import { store } from '@ice/stark-data';

const userInfo = store.get('user'); // get UserInfo

function showLang(lang) {
  console.log(`current language is ${lang}`);
}

store.on('language', showLang, true); // add callback for 'language', callback will be called whenever 'language' is changed

store.off('language', showLang); // remove callback for 'language'

Event

Global Event, unified management of all events

• on(key, callback) callback will be called with (...rest)
• off(key, callback)
• emit(key, ...rest)

example

// Framework
import { event } from '@ice/stark-data';

function fresh(needFresh) {
  if (!needFresh) return;

  fetch('/api/fresh/message').then(res => {
    // ...
  });
}

event.on('freshMessage', fresh);

// Sub-application A
