sprockets-jst-str is a Sprockets plugin which simply returns the entire template as an escaped JavaScript string. For example, a file named hello.jst.str:
<h1 class="foobar">
Hello <%= get('name') %>
</h1>
would turn into:
'<h1 class="foobar">\n Hello <%= get(\'name\') %>\n</h1>';
In addition to single quotes, all backslashes, tabs and line breaks are also replaced with their respective symbols.
