Create a new index.template.html file alongside index.html and copy its contents. Then, replace the body content with the special <!--vue-ssr-outlet--> comment:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Fashion Store</title>
</head>
<body>
<!--vue-ssr-outlet-->
</body>
</html>
This special comment will be replaced by the rendered markup on the server.
