*2: How to create a template file

Creating a template file is easy. At a minimum, all you need to do is load /markdown-preview-websocket.js and pass a callback function with the necessary processing to connectMarkdownPreview.

Sample code is presented below.

<!doctype html>
<html>
  <head>
    <title>Minimum Template Sample</title>
  </head>
  <body>
    <pre id="raw-markdown"></pre>
    <script type="module">
      import { connectMarkdownPreview } from "/markdown-preview-websocket.js";
      connectMarkdownPreview(({ markdown }) => {
        document.getElementById('raw-markdown').innerHTML =
          markdown.replace(/</g, '&lt;').replace(/>/g, '&gt;');
      });
    </script>
  </body>
</html>
