Gitbook Plugin noopener

This extension adds `rel="noopener noreferrer" to any links which are external links or defined with target '_blank'. This improves the security of the site:

• noopener: Instructs the browser to open the link without granting the new browsing context access to the document that opened it — by not setting the Window.opener property on the opened window (it returns null).
• noreferrer: Prevents the browser, when navigating to another page, to send this page address, or any other value, as referrer via the Referer: HTTP header.

Installation

Add the plugin to your book.json:

{
    "plugins" : [ "noopener" ]
}
