vue 项目中的 vuex 简单封装

 index.js ：

import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex)
import state from './state'
import actions from './actions'
import mutations from './mutations'
import modA from './modules/modA.js'
export default new Vuex.Store({
  state,
  actions,
  mutations,
  modules: {
    modA
  }
})

 state.js :

const state = {
  count:1
};
export default state;

mutations.js :

const mutations = {
  increment(state,param){
    state.count += n
  }
}
export default mutations;

actions.js :

const actions = {
  incrementAct({commit},argNum){  //argNum为参数
    commit('increment',augNum)
  }
}
export default actions;

modA.js :

// A 模块的内容
const state = {
  //A模块的数据
};
const mutations = {
  //A模块的 mutations
};
const actions = {
  //A模块的actions
};
export default {
  state,
  actions,
  mutations
};
