简化vuex的状态管理方案的方法

// model.js
import Vue from 'vue';
import Vuex from 'vuex';
import MuseModel from 'muse-model';

export const store = Vuex.Store({
 strict: true
});

export default new MuseModel(store);

// count.js
export default {
  namespace: 'demo',
  state: {
    count: 1
  },
  add () {
    return {
      count: this.state.count + 1
    }
  },
  sub () {
    return {
      count: this.state.count - 1
    }
  }
}

<template>
<div>
  <button@click="add">+</button>
  {{count}}
  <button@click="sub">-</button>
</div>
</template>
<script>
import model from './model';
import CountModel from './count';
const CountUI = {
  name: 'count-ui'
};

export default model.connect(CountUI, CountModel);
</script>

export default {
  //....
  addTimeOut () { // 异步处理
    return new Promise((resolve, reject) => {
     setTimeout(() => {
      resolve({
       count: this.state.count + 1
      });
     }, 1000);
    });
  }
}
