vuex 如何配置多个 modules

一、结构

 

 二、index.js

import Vue from "vue";
import Vuex from "vuex";

Vue.use(Vuex);

// https://webpack.js.org/guides/dependency-management/#requirecontext
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
});

export default store;

三、modules 下新建模块js 文件 例如：app.js

export default {
  state: {
    appInfo:null
    //...
  },
  mutations: {
    setAppInfo(state, value) {
      state.appInfo= value;
    }
  },
  actions: {
    setAppInfoAction({ commit }, value) {
      commit("setAppInfo", value);
    },
  },
  getters:{}
};

四、main.js 中引入

import store from "./store";
new Vue({
  router,
  store,
  render: h => h(App)
}).$mount("#app");
