How to use less with jQuery?

less has been used with vue before, but now it has to be used with jquery. How to use it?
1. Use less.cmd to generate css
2. Or

<!DOCTYPE html>
<html>
    <head>
        <title>nav</title>
        <meta charset="UTF-8">
        <meta http-equiv="X-UA-Compatible" content="IE=9">
        <link rel="stylesheet/less" href="less/lianxi.less">
        <script src="js/less.min.js"></script>
    </head>
    <body>
        <div class="father">
            fjlsjflsfj
        </div>
    </body>
</html>

so compile directly at load time
3. The project is mobile, is it particularly energy-consuming when compiling on the mobile side when loading?
do you know? please ask!
