vuex的modules引入

import Vue from ‘vue‘;
import Vuex from ‘vuex‘;
import getters from ‘./getters‘;
Vue.use(Vuex);

const modulesFiles = require.context(‘./modules‘, false, /\.js$/);
const modules = modulesFiles.keys().reduce((modules, modulePath) => {
  // set ‘./app.js‘ => ‘app‘  $1是正则里边的捕获，(.*)内的内容；
  const moduleName = modulePath.replace(/^\.\/(.*)\.\w+$/, ‘$1‘);
  const value = modulesFiles(modulePath);
  modules[moduleName] = value.default;
  return modules;
}, {});

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