有不足之处还望各位多多指点

【演示效果】：这是打包之后上传服务器的ng效果，首次加载速度会有点慢，请耐心等待 http://www.bester.wang

【升级版本】：整合ionic4，支持打包双系统app，接近原生app的体验，真正的即时通讯，真正的聊天app，对任何想整合im的项目都是零侵入性，随时随地整合聊天系统到你的原有项目，就是这么简单

【后端im技术简介】：springboot+cloud，让开发更简单，微服务让分布式和集群更简单，支持不停机更新，基于业界标杆netty进行im核心开发，性能爆表

【angualr前端模板简介】：采用angular+@angular/cli+@angular/router+@ngrx/store等技术开发的angular版仿微信界面聊天室，主要实现了下拉刷新、长按右键菜单、发送消息、表情(动图)，图片、视频预览，打赏、红包等功能。

技术架构：

• MVVM框架：angular8 + @angular/cli + @angular/router
• 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

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

学习不停歇、研发不终止，近段时间一直在捣鼓angular框架技术，发现并没有想象的那么难，不过也踩过一些坑，之前有使用vue开发过仿微信聊天，想着基于angular+angular-cli+angular-router+ngrx/store+rxjs+webpack+node+wcPop等技术开发的仿微信angular-chatroom聊天室实战项目，实现了下拉刷新、聊天消息右键菜单、发送消息、表情(动图)，图片、视频预览，红包打赏等功能

技术架构：

• 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
