VueX自动化注册

在 store/index.js 中写入

const modulesFiles = require.context('./modules', true, /\.js$/)
// you do not need `import app from './modules/app'`
// it will auto require all vuex module from modules file
const modules = modulesFiles.keys().reduce((modules, modulePath) => {
  // set './app.js' => 'app'
  const moduleName = modulePath.replace(/^\.\/(.*)\.\w+$/, '$1')
  const value = modulesFiles(modulePath)
  modules[moduleName] = value.default
  return modules
}, {})

const store = new Vuex.Store({
  modules,
  getters,
})

export default store

此时只要在 store/modules 目录下定义相应的内容就行了
如在 store/modules/app.js 定义VueX模块的内容

const state = {
  sidebar: {
    opened: Cookies.get('sidebarStatus') ? !!+Cookies.get('sidebarStatus') : false,
    withoutAnimation: false
  },
  device: 'desktop',
  language: getLanguage(),
  loading: {},
}

const mutations = {
  SET_ROUTER_BEFORE_TIME: (state, time) => {
    state.routerBeforeTime = time
  },
}

const actions = {
  setRouterBeforeTime({ commit }, time) {
    commit('SET_ROUTER_BEFORE_TIME', time)
  },
  setCurClueCode({ commit }, clueObj) {
    commit('SET_CUR_CLUE_CODE', clueObj)
  },
}

export default {
  namespaced: true,
  state,
  mutations,
  actions
}

一般调用

this.$store.dispatch('app/setCurClueCode', arguments)

一般取值

this.$store.state.app.device
