最近一直在学习angular，毕竟ng在前端开发中有很庞大的用户量，值得尝试一下，几天学习下来，发现并没有想象的难，如是就利用angular全家桶技术开发了个angular-chatroom仿微信聊天室项目。
使用技术：
- MVVM框架：angular8.0 / @angular/cli
- 状态管理：@ngrx/store / rxjs
- 地址路由：@angular/router
- 弹窗组件：wcPop
- 打包工具：webpack 2.0
- 环境配置：node.js + cnpm
- 图片预览：previewImage
- 轮播滑动：swiper
package.json依赖安装
