react-scripts build忽略条件css导入 [英] react-scripts build ignores conditional css imports

问题描述

我试图为我的React项目有条件地要求使用CSS，并且它在本地运行.但是，当react js执行react-scripts build命令时，所有css文件都被捆绑到一个文件中，并且条件导入不再起作用.

I am trying to conditionally require css for my react project and it works locally. However, when the react-scripts build command is executed by react js all css files get bundled into one and the conditional import no longer works.

if(isSmartPhoneOrTablet()){
    require("./mobileStyle.css");
}else {
    require("./style.css");
}

"build":反应脚本构建"

推荐答案

您可以尝试

var cssfile;
if(isSmartPhoneOrTablet()){
    cssfile = "./mobileStyle.css";
}else {
    cssfile = "./style.css";
}
require(cssfile);
