在5+app的index.html页通过链接访问自己的vue项目,从而实现打包时,只有一个链接,在更新代码时,只需要更新一次代码,即可实现在浏览器,安卓,ios同时实现更新。
在链接访问vue项目时,因为vue项目时单页面的项目,所以在首页加载时会将所有需要的东西一次性加载出来,对于一些网络差或者设备差的设备,在打开时白屏会持续数秒,为了解决这个问题,可以从项目优化和使用过渡动画解决。
项目优化可以减少白屏时间,但是无法在设备性能差的情况下做到0延迟。所以需要同时着手。
目前使用过渡动画解决方案,即在vue项目的index.html页面加上过渡动画代码。性能优化正在进行中,过渡动画代码如下:
