Mark External Links

Add target and rel attributes to external links.

Automatically detects new links added to the document by installing a mutation observer. This makes it safe to use when adding content via AJAX, using frontend frameworks, etc.

Before

<a href="https://external.web">link</a>

After

<a href="https://external.web" target="_blank" rel="nofollow noopener noreferrer">link</a>

Installation

npm install mark-external-links

Usage

Import and call markExternalLinks().

import markExternalLinks from 'mark-external-links'
 
markExternalLinks()

Options

All options and their defaults:

markExternalLinks({
  target: '_blank',
  rel: 'nofollow noopener noreferrer',
  test: link => link.hostname !== window.location.hostname
})

In the browser

If you don't have the luxury of using a bundler, slap it in a script tag and call it a day.

<script src="https://unpkg.com/mark-external-links"></script>
<script>
  markExternalLinks.markExternalLinks()
</script>
