node-esapi

node-esapi is a minimal port of the ESAPI4JS (Enterprise Security API for JavaScript) encoder.

Installation

$ npm install node-esapi

Usage

var ESAPI = require('node-esapi');
ESAPI.encoder().encodeForHTML('<p>This is a test</p>');

Encoder Functions

The encoder() returns an object with the following main functions:

• encodeForHTML
• encodeForCSS
• encodeForJS = encodeForJavaScript = encodeForJavascript
• encodeForURL
• encodeForHTMLAttribute
• encodeForBase64

Middleware

The ESAPI has a function for creating express middleware to serve client side scripts of ESAPI.

app.use(ESAPI.middleware());

// Now in your HTML you can do
<script src="/esapi/esapi.js"></script>
<script src="/esapi/resources/i18n/ESAPI_Standard_en_US.properties.js"></script>
<script src="/esapi/resources/Base.esapi.properties.js"></script>
<script>
	org.owasp.esapi.ESAPI.initialize();
	//Here you have access to the $ESAPI object and can do
	$ESAPI.encoder().encodeForHTML('<p>This is a test</p>');
</script>
