前言

前人栽树后人乘凉，骨架屏到现在已经非常多的解决方案，用之即可 ···

方式

• 安装插件vue-skeleton-webpack-plugin
• vue.config.js配置

const path = require('path')
const SkeletonWebpackPlugin = require('vue-skeleton-webpack-plugin');
module.exports = {
  css: {
    // css拆分ExtractTextPlugin插件，默认true - 骨架屏需要为true
    extract: true,
  },
  configureWebpack: (config)=>{
    // vue骨架屏插件配置
    config.plugins.push(new SkeletonWebpackPlugin({
      webpackConfig: {
        entry: {
          app: path.join(__dirname, './src/config/skeleton.js'),
        },
      },
      minimize: true,
      quiet: true,
    }))
  },
}

• 新增一个骨架屏注入js文件，这里命名为skeleton.js，放置在config文件夹下

import Vue from 'vue';
import Skeleton from '../static/skeleton/skeleton-2';

export default new Vue({
  components: {
    Skeleton,
  },
  render: h => h(Skeleton),
});

  animation: skeleton-stretch 0.5s -0.3s linear infinite alternate;
}

@keyframes skeleton-stretch {
  from {
    transform: scalex(1);
  }
  to {
    transform: scalex(0.3);
  }
}
</style>

• 为了加载效果更佳，避免浏览器加载css阻塞，在main.js新增如下配置

const app = new Vue({
  store,
  router,
  render: h => h(App)
})

// 骨架屏: 全局记录挂在方法
window.mountApp = () => {
  app.$mount("#app");
};

// 骨架屏：如果js晚于css加载完成，那直接执行渲染
if (process.env.NODE_ENV == "development" || window.STYLE_READY) {
  window.mountApp();
}

备注

到此骨架屏就完成了，这仅仅是固定样式的骨架屏，有时间再研究运行时渲染方案
