markdown link opening in new tab

If you have access to JavaScript, you can run a simple script to handle this for you wherever your markdown is rendered:

const anchors = document.querySelectorAll('a');
anchors.forEach((a) => {
  a.setAttribute('target', '__blank');
  a.setAttribute('rel', 'noopener noreferrer');
});

The kramdown syntax:

[link name](url_link){:target="_blank"}

can be parsed into HTML using the kramdown online editor: https://kramdown.herokuapp.com/ Then you can paste the HTML syntax into your markdown document.
I used it because I already had quite a few kramdown references, and wanted to avoid retyping them in HTML.

As far as I could find, this is not possible on GitHub currently. See good answer on this from Plaul here. I hope they will fix it soon, as it seems searching for an answer that this is something a lot of people would like to see.

Doing some quick research - Markdown by default does not support this. Some solutions include using plugins like Kramdown, but I think the best solution is just to use an HTML tag in your markdown file. (as pointed out in the comment above ^)
