I think it is a neccessar thing with glitch. But as I stated in my previous post, I wasnt sure. In general you don’t want to load package.json files with starting the node server.
But I looked a bit at your service. I like it. But I am not so sure about how well it works in respect to the user story, if you give it a ftp protocol as url. Then it seems to give back a shortened url. Which I think he shouldn’t. As well when he redirected me I ended on a dead page. So I would like to see it also checks for the right protocol, (http, https). But I don’t know if it is necessarily, I’m not so sure.
