What are remark-external-links's main functionalities?

Adding attributes to external links

This feature allows users to automatically add specific attributes such as target='_blank' and rel='nofollow noopener noreferrer' to external links in Markdown content. This enhances security by preventing tabnapping and improves SEO through 'nofollow'. The code sample demonstrates how to set up the plugin with Remark to process a simple Markdown string.

const remark = require('remark');
const html = require('remark-html');
const externalLinks = require('remark-external-links');

remark()
  .use(externalLinks, {target: '_blank', rel: ['nofollow', 'noopener', 'noreferrer']})
  .use(html)
  .process('Check out [Google](https://google.com)!', function (err, file) {
    console.log(String(file));
  });
