深色和浅色模式：如何切换清单和图标？

Question

清单和图标取决于浅色/深色模式，当用户更改操作系统中的模式时，有什么方法可以更改它们吗？

我已经触发了事件侦听器

  window.matchMedia('(prefers-color-scheme: dark)').addEventListener( "change", (e) => {
    if (e.matches) console.log('your in dark mode);
  });

但清单是从反应公共文件夹加载的..

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />
    <meta name="theme-color" content="#000000" />
    <meta
      name="description"
      content="Web site created using create-react-app"
    />
    <link rel="apple-touch-icon" href="logo192.png" />
    <link rel="manifest" href="%PUBLIC_URL%/manifest.json" />
    <title>My Site</title>
  </head>
  <body>
    <noscript>Please enable JavaScript to run this app.</noscript>
    <div id="root"></div>
  </body>
</html>

不确定如何处理也在公共文件夹根目录中的图标。此外，主题颜色的元标记也需要更改。

使用@kishore的建议，我已经设法让favicon正常工作，我确信有人更好地可以收紧我的代码，但它有效，在html中我添加了一个id...

<link rel="shortcut icon" id='favicon' href="%PUBLIC_URL%/favicon.ico" />
<link rel="manifest" id='manifest' href="%PUBLIC_URL%/manifest.json" />

然后在头部我添加了......

    <script>
      const usesDarkMode = window.matchMedia('(prefers-color-scheme: dark)').matches || false;
      const favicon = document.getElementById('favicon');
      const manifest = document.getElementById('manifest');

      function switchIcon(usesDarkMode) {
        if (usesDarkMode) { 
          favicon.href = '%PUBLIC_URL%/favicon-dark.ico';
          manifest.href='%PUBLIC_URL%/manifest-dark.json' 
        } else {
        favicon.href = '%PUBLIC_URL%/favicon-light.ico';
        manifest.href='%PUBLIC_URL%/manifest-light.json' 
        }
      }

      window.matchMedia('(prefers-color-scheme: dark)').addEventListener( "change", (e) => switchIcon(e.matches));
      switchIcon(usesDarkMode);
    </script>
