think-react-store/middlewares/cache.js

基于react hooks 和 context 实现的类似与 redux 的数据流工具

import pick from 'ramda/src/pick'
// import mergeDeepRight from 'ramda/src/mergeDeepRight'

/**
 * 中间件参数
 * @param {Object} store store
 * @param {Object} prevState 更新前的state值
 * @param {Object} nextState 更新后的state值
 * @param {Object} action 派发的action
 */
export default function cache(store, prevState, nextState, action, actionAsync, asyncKey, cache){
  const CACHE = 'react-store:cache';

  if(cache && cache.length){
    localStorage.setItem(CACHE, JSON.stringify(pick(cache, nextState)))
  }
}
