xss 's direct dependencies. Data on all dependencies, including transitive ones, is available via CSV download.The xss package is a popular JavaScript library utilized for the prevention of Cross-Site-Scripting(XSS) attacks. Its main function is to sanitize untrusted HTML input based on a whitelist of acceptable HTML tags and attributes. This helps in maintaining the security of your web applications by preventing malicious scripts from being injected and executed on the client-side.
To use the xss package in your JavaScript project, first, you need to install it from npm using the following code:
npm install xss
You can then require and utilize the xss function like the example given below:
var xss = require("xss");
var html = xss('<script>alert("xss");</script>');
console.log(html);
In the example, the xss function is sanitizing the input HTML string to ensure no harmful scripts are embedded within it.
If you're using the xss package in a browser environment, the setup is slightly different. Reference the xss.js file in a script tag, then use the filterXSS function similarly to the xss function from the Node.js example.
<script src="https://rawgit.com/leizongmin/js-xss/master/dist/xss.js"></script>
<script>
var html = filterXSS('<script>alert("xss");</script>');
alert(html);
</script>
Remember not to use this URL in a production environment.
The documentation for the xss package can be found in its GitHub repository readme. More detailed information about features, custom filter rules, default whitelist, and examples of usage can be found here. The API reference, including detailed explanations of the onTag, onTagAttr, onIgnoreTag, onIgnoreTagAttr, and the custom escaping function, is described in detail in the readme.
