On the buttons below the title, there should be an "archive" one for URL posts. It could use archive.is. The first time it's pressed an archive will be created, then automatically after that it'll go to the archived website. That's all done on their side as well.
You (Polsaker, I know you're reading this!) would just have to get the URL and then parse it into
javascript:void(open('https://archive.today/?run=1&url='+encodeURIComponent(POST URL HERE)))
Yes? No?
What polsaker said, but here's some more info..
Having that built in to phuks would require our server to ping their server, wait for a reply, then make the post if it can, or detect that it broke and make more options.. We don't want phuks servers to send and wait for replies from another service.
BUT, we might be able to add a thing that adds the archive link after the post is created, kinda like how post flairs work.
I use an archive bookmarlet with similar code in it. I def want this too.
