fixed-csp-parse

csp-parse

NodeJS module for parsing Content-Security-policy policies.

The module takes raw CSP policy strings, and parses them into Policy objects. From there the objects can be manipulated (adding/removing different values from the directives).

Afterwards policy.toString() can be called to get the updated policy.

Installation

npm install csp-parse

Or to use as plain javascript, remove the last line.

Usage

var Policy = require('csp-parse');

var example = "script-src 'self' www.google-analytics.com ajax.googleapis.com; style-src 'self';"
var policy = new Policy(example)

policy.get('script-src') // "'self' www.google-analytics.com ajax.googleapis.com"
policy.add('script-src', 'code.jquery.com');
policy.get('script-src') // "'self' www.google-analytics.com ajax.googleapis.com code.jquery.com"

policy.toString() // "script-src 'self' www.google-analytics.com ajax.googleapis.com code.jquery.com; style-src 'self';"

policy.set('connect-src', 'socket.webserver.com socket2.webserver.com');

policy.toPrettyString()
//script-src
//  'self' www.google-analytics.com ajax.googleapis.com code.jquery.com;
//style-src
//  'self';
//connect-src
//  socket.webserver.com socket2.webserver.com

For more examples see the test cases.
