vuex的五个属性是什么

import Vue from 'vue'
import Vuex from 'vuex'
import user from './modules/user'
import global from './modules/global'
import getters from './getters'
Vue.use(Vuex)
const store = new Vuex.Store({
  modules: {
    user
  },
  getters
})
export default store
　　在store文件下的getters.js中引入
const getters = {
  self: state => state.user.self,
  token: state => state.user.token,
  currentCommunity: (state, getters) => {
    let cid = getters.currentCommunityId
    return getters.communities.filter(item => {
      return item.communityId === cid
    })
  }
}
export default getters
　　在modules文件下的user.js写代码
const user = {
        state:{
            self: null,
            token: '',
        },
        mutations:{
            SET_SELF: (state, self) => {
                 state.self = self
             },
             SET_TOKEN: (state, token) => {
                 state.token = token
             }
        },
        actions:{
             login ({ commit }, res) {
                  commit('SET_SELF', res.self)
                  commit('SET_TOKEN', res.token
            }       
}
export default user

　　dispatch：异步操作，写法： this.$store.dispatch('mutations方法名',值)
　　commit：同步操作，写法：this.$store.commit('mutations方法名',值)
