}));Template integration
Most of the times you will have something like a header.ejs and footer.ejs which will be included in a somePage.ejs as a re-usable template. But sometimes you want to insert CSS- or JavaScript-Files into your header and/or footer from your somePage. Sending locals along res.render() is not the best solution.
This will be implemented like this:
header.ejs
<!DOCTYPE html>
<html lang="en">
<head>
<title><%= title() %></title>
<meta charset="UTF-8">
<%- head(); -%>
<%- scripts('header'); %>
<%- styles(); -%>
</head>
<body>footer.ejs
<%- scripts('footer'); %>
</body>
</html>somePage.ejs
<%
setTitle('Some Page');
addHead('<meta name="description" content="This is some page">');
addHead('<meta name="author" content="Timo Mämecke">');
addStyle('style.css');
addStyle('print.css', { media: 'print' });
addScript('header', 'script1.js', { async: 'async' });
addScript('footer', 'script2.js');
%>
<% include header %>
<h1>Lorem ipsum</h1>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p>
<% include footer %>The rendered HTML will look like this:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Some Page</title>
<meta charset="UTF-8">
<meta name="description" content="This is some page">
<meta name="author" content="Timo Mämecke">
<script src="/static/js/script1.js" async="async"></script>
<link href="/static/css/style.css">
<link href="/static/css/print.css" media="print">
</head>
<body>
<h1>Lorem ipsum</h1>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p>
<script src="/static/js/script2.js"></script>
</body>
</html>Options
cssPathwill be prepended to the filename of the CSS hrefjsPathwill be prepended to the filename of the script srcurlArgsare extra query string arguments appended to relative path URLs
The above configuration is ignored if absolute url is provided. eg:
addScript('footer', 'https://cdnjs.cloudflare.com/ajax/libs/require.min.js')OR
addScript('footer', '//cdnjs.cloudflare.com/ajax/libs/require.min.js')OR
addScript('footer', 'http//cdnjs.cloudflare.com/ajax/libs/equire.min.js')Then the original url is used and for example in the second case when scripts('footer')
is called, no matter what configuration is used, it will result to:
<script src="//cdnjs.cloudflare.com/ajax/libs/require.min.js"></script>Methods
