uniapp-welive一款基于uni-app+vue3+pinia+vk-uview
等技术搭建跨端仿抖音直播商城项目。
uniapp-welive支持编译到多端H5+小程序+App端,且效果基本保持一致性。
uniapp-welive小视频/直播页面采用Nvue编码开发方式。
短视频采用全屏沉浸式上下滑动效果,底部mini播放进度条。
项目结构目录如下,遵循vue3 setup
语法规范编码开发项目。

直播模块包含了顶部信息栏、加入直播间/送礼物提示、讲解商品、滚动聊天信息、底部toolbar菜单栏。
可能大家比较关心聊天消息自适应布局如何实现?

整体UI效果还是保持一致的,虽说在Nvue中有些出入,但是影响不大。
Oky,综上就是uni-app+vue3+pinia开发跨端直播商城的一些实例分享,希望大家喜欢哈!
