vuex的使用和简易实现

import Vue from 'vue'
import Vuex from 'vuex'
import products from './modules/products'
import cart from './modules/cart'

Vue.use(Vuex)

export default new Vuex.Store({
 strict: process.env.NODE_ENV !== 'production',
 state: {
  count: 0,
  msg: 'Hello Vuex'
 },
 getters: {
  reverseMsg (state) {
   return state.msg.split('').reverse().join('')
  }
 },
 mutations: {
  increate (state, payload) {
   state.count += payload
  }
 },
 actions: {
  increateAsync (context, payload) {
   setTimeout(() => {
    context.mit('increate', payload)
   }, 2000)
  }
 },
 modules: {
  products,
  cart
 }
})

const state = {}
const getters = {}
const mutations = {}
const actions = {}

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

 name: 'ArticleMeta',
 props: {
  article: {
   type: Object,
   required: true
  },
  user: {
   type: Object
  }
 },
 data () {
  return {
   currentArticle: this.article, isDelete: false
  }
 },
