After introducing the file , Put the exposed namespace into the global , Named empty exposed classes , For use 

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <script src="./dist/components.js"></script>
    <script src="./dist/page.js"></script>
</head>
<body>
    <script> new Home.Page() </script>
</body>
