博客都已静态,想再提速,要么换国内云服,要么优化一个个 JS 加载。立竿见影办法是使用 CDN 来加载,或者前端延迟加载,甚者后端判断按需加载。

在需要加载的一串 JS 里,找来找去,Valine 这货最强大 💪

撸起袖子,月干!

代码来自:hugo-theme-meme/valine.html,好使! 👍

<script type="text/javascript">
loadComments();
function loadComments() {
  if (typeof Valine === 'undefined') {
    var getScript = (options) => {
      var script = document.createElement('script');
      script.defer = true;
      script.crossOrigin = 'anonymous';
      Object.keys(options).forEach((key) => {
          script[key] = options[key];
      });
      document.body.appendChild(script);
    };
    getScript({
      src: 'https://cdn.jsdelivr.net/npm/valine@1.3.10/dist/Valine.min.js',
      onload: () => {
        newValine();
      }
    });
  } else {
    newValine();
  }
}
function newValine() {
  new Valine({
    //原配置
  });
}
</script>
