README

secure-handlebars-helpers

This handy client-side script registers the implementations of the contextual XSS escaping filters as handlebars' helpers, and is solely designed to be used with templates processed with the secure-handlebars package (e.g., <title>{{{yd title}}}</title> is one of the typical patterns of a processed template).

Quick Start

Client-side (browser)

Download the latest version at dist/secure-handlebars-helpers.min.js, and embed it after the handlebars script file.

ipt type="text/javascript" src="dist/handlebars.js"></script>
ipt type="text/javascript" src="dist/secure-handlebars-helpers.min.js"></script>

ipt type="text/javascript">
templateSpec = Handlebars.compile("<title>{{{yd title}}}</title>");
tml is assigned <title>&lt;script>alert('xss')&lt;/script></title>
data = {title: "<script>alert('xss')</script>"};
html = templateSpec(data);
ript>

Note: Read more about the underlying principle of contextual output filtering at xss-filters.
