redirect-whitelister

npm install redirect-whitelister

Usage:

const RedirectWhitelister = require('redirect-whitelister');
const whitelister = new RedirectWhitelister(<domain-list>);

const validUrl = whitelister.verify('https://example.com/test/1234?s=test');

Options:

• domain-list - Either an array or single string domain. Domains may contain wildcards eg: test.*.example.com. You can also use simple regex (see tests cases).

Overriding Protocols:

By default only http and https are allowed. If you need to change this, say to support a custom protocol for a mobile app:

const RedirectWhitelister = require('redirect-whitelister');
const whitelister = new RedirectWhitelister(<domain-list>);

whitelister.allowedProtocols = ['gopher:', 'http:', 'https:'];

Validating a url

• verify(<url>) - Returns a boolean if the url contains a domain that matches any of the allowed domains.
