vue2.0仿微信聊天室|vue-chatRoom实例项目|vue全家桶仿微信聊天app

基于vue+vuex+vue-router+webpack2.0+es6+wcPop+iconfont等技术开发的仿微信界面聊天室，之前使用h5开发过一版h5聊天室，实现了微信聊天功能、发送消息/表情，图片、视频预览，打赏、红包等功能。

技术栈

MVVM框架：Vue.js 2.0
状态管理：Vuex
页面路由：Vue-router
弹窗插件：wcPop
打包工具：webpack 2.0
环境配置：node.js + cnpm
图片插件：vue-photo-preview

页面地址路由、登录拦截：

/*
 *  页面地址路由js
 */ 
import Vue from 'vue'
import _router from 'vue-router'
import store from '../vuex'

Vue.use(_router) //应用路由

const router = new _router({
