⚡️“Tweet this page” bookmarklet

Friday, August 23rd, 2019 at 9:42 pm

Update: Moved the code to GitHub, make sure to drag it from there to your toolbars
Update: Fixed now for Chrome – there were some issues with whitespace :(

I like tweeting about pages I read in the following format:

"Headline"
https://example.com

Most “share this” buttons add a lot of cruft and if there is none, it is annoying having to copy the text first and then the URL into Twitter.

With this bookmarklet, you can highlight some text, click the bookmarklet and get a tweet window in a new tab. This is the source in a more readable manner – this will not work as a bookmarklet, see the link below instead!

(function(){
    n=getSelection().anchorNode;
    if(!n) {
        t = document.title;
    } else {
        t = n.nodeType === 3 ? n.data : n.innerText;
    }
    t = '“' + t.trim() + '”\n\n';
    window.open(
        `https://twitter.com/intent/tweet?text=
        ${encodeURIComponent(t)}
        ${document.location.href}`
    )
})();

Explanation:

  • We wrap the whole thing in an IIFE to avoid the browser redirecting to “javascript://”
  • We get the anchorNode of the current Selection object
  • If there is no highlighted text, we grab the document title
  • We check the type. If it’s a text node, we read the data, if it is HTML, we get the innerText
  • We remove any whitespace, add the quotes and some line breaks
  • We open a window (which these days results in a new tab) and call the Twitter intend with the text followed by two line breaks and the URL of the document.

That’s it. Drag the bookmarklet to the toolbar from the GitHub Demo page or check the code.

Voilà, happy tweeting.
