Hello there!
Thanks for Schnack, using it for my own Ghost blog. If it didn't exist I would have built it the same way, super happy you did it!
Just a quick issue report to let you know that, in my case I didn't configure web-push, and when I'm logged in as an admin there's a 404 to push.js which is still requested. Not happening for anonymous sessions AFAIK.
As well, another quick bug, I'm using the sendmail notifier, and the direct link to the comment in the email notifications is dangling, eg: Permalink: https://journal.valeriansaliou.name/announcing-sonic-a-super-light-alternative-to-elasticsearch/#comment-undefined (it's not passing the comment ID, but rather undefined).
Thanks for all!
