title: Refresh less css which has other imported less files without page load
body: <p>I want to use watch mode in my development environment. It works fine with single less file. But I have so many less files which are imported to app.less. My app.less looks </p>
  
  <pre><code>@import "variables";
  @import "mixins";
  </code></pre>
  
  <p>It seems I can not use watch mode in this setting. Is there any other ways?</p>
