Here's how to make a PDF with Handlebar.js HTML templates:
<html>
<head>
<script src="<a href="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js%22></script" target="_blank" rel="nofollow noopener noreferrer">https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script</a>>
<script src='<a href="https://dl.dropboxusercontent.com/u/243251/handlebars-v4.0.5.js'></script" target="_blank" rel="nofollow noopener noreferrer">https://dl.dropboxusercontent.com/u/243251/handlebars-v4.0.5.js'></script</a>>
<script id="entry-template" type="text/x-handlebars-template">
<div class="entry">
<h1>{{title}}</h1>
<div class="body">
{{body}}
</div>
</div>
</script>
</head>
<body>
</body>
<script>
var source = $("#entry-template").html();
var template = Handlebars.compile(source);
var context = {title: "My New Post", body: "This is my first post!"}
var html = template(context);
document.body.innerHTML = html;
</script>
</html>
