uniapp实现聊天｜uniapp聊天源码_uniapp聊天小程序源码

泡泡IM uniapp版聊天源码是一套完整的基于uniapp开发的聊天软件源码，可编译成微信小程序、安卓 IOS APP聊天软件、H5网页聊天室。uniapp聊天源码未加密，无外部依赖，可私有化部署，可二次开发。文档全面，接口丰富，方便二次开发或者对接现有项目。

聊天软件主要通能
1、支持发语音、文字、图片、表情、录制视频
2、支持私聊、群聊
3、群聊支持建群、退群、解散群组、禁言、踢人、拉人进群、群备注等功能、管理员
4、个人信息支持更改昵称、头像、个性签名等
5、支持查看历史消息、离线消息
6、支持好友查找、好友申请、同意好友申请、拒绝申请、删除好友，好友备注
7、支持消息撤回，脏字过滤
8、支持通讯录，按字母顺序排列
9、离线消息栏推送能力
10、管理后台

聊天源码技术栈：
