在webpack中设置初始化loading
项目基于create-react-app脚手架，所以先创建项目，然后npm run eject在config文件目录下加入loading；
1、在plugins的html模版中添加变量
new HtmlWebpackPlugin(
Object.assign(
{},
{
inject: true,
template: paths.appHtml,
// 初始化加载loading
// loading: {
// html: `<h1 style="display: flex;width:100vw;height:100vh;justify-content: center;align-items: center;margin-top: -27vh;overflow: hidden;">LOADING...</h1>`
// }
},
isEnvProduction
? {
minify: {
removeComments: true,
collapseWhitespace: true,
removeRedundantAttributes: true,
useShortDoctype: true,
removeEmptyAttributes: true,
removeStyleLinkTypeAttributes: true,
keepClosingSlash: true,
minifyJS: true,
minifyCSS: true,
minifyURLs: true,
},
}
: undefined
)
),
2、在public的html模版中添加变量
<!-- 首屏加载的时的loading -->
<%= htmlWebpackPlugin.options.loading.html %>
