Failure Detection Handler

[amcdnl]

Problem

If a user is using a ad blocker, sometimes it will not start up fullstory. I would like the ability to catch if the error occurs and handle it.

Proposal

You could do something like make Fullstory.init return a Promise and error if it fails, so you could do:

(async () => {
   try {
      await Fullstory.init({ orgId: 'asdf' });
   } catch (e) {
        alert('Kindly turn that ad blocker off');
   }
}();

Hey Austin! Thanks for proposing this, sorry for the delayed reply. Let me circle back with some other folks on my team to review.

I ended up using this: https://www.npmjs.com/package/use-ad-block-detection - would be nice to have this built in though.

The way these ad blockers typically work is blocking the URL pattern to the recording script fs.js. It would be useful to have even a naive timeout on whether FS is ever loaded into the window. Another use case is content-security-policy that could also block fs.js. Thanks for bringing it up.

@van-fs - Yup - the ad block hook I demonstrated above just tries to request the script and when it fails it handles the exception. This of course causes duplicate calls ( though cached ) so it would be grat to handle this in the lib itself.
