基于 uniapp 开发的仿抖音小程序组件（超高性能）

GIF 截图效果

• GIF 帧率不够，实际真机效果非常丝滑

注：组件使用 vue3+typescript 开发

• 全局仅渲染 3 个 swiper-item
• 实测，不管加载多少数据也能丝滑滚动
• 适用于 vue3，vue2 请自行修
• 自动预加载视频
• 首次渲染优化

快速开始，下载插件后请按照此方法运行调试

1. 安装 nodejs: https://nodejs.org/en/
2. 安装依赖: npm i
3. 运行项目: npm run dev:mp-weixin
4. 构建项目资源: npm run build:mp-weixin
5. 打开小程序开发工具导入dist/dev/mp-weixin 即可
6. 真机预览，请点小程序开发工具上的预览，扫码真机预览即可
