Why does accessing the session object make Express-Session work?

My sessions suddenly stopped being saved, and cookies stopped being set. All routes were working, and Postman was also not receiving cookies (so I ruled out cors). I discovered that accessing the session object immediately after the middleware fixed the issue. So this code was all that was needed: ```app.use((req, res, next) => {...

DevDependency vs Dependency, npm.

Not a big deal at all, just curious, but I come across this all the time: Packages that I feel should be dev dependencies but aren't. The latest is Mocha, but like I said it feels pretty frequent. Does it not really matter that much? I don't really know enough to comment, so maybe I'm just way off base 🙂...

Can strips pre-built checkout only be used surrounded by a form attribute?

I’m having trouble integrating stripe using firebase. My code seems correct but every time I click “checkout” nothing occurs even though I set it to redirect to stripe checkout. Is there a way to use it without having the form attribute around the button?...

SQL foreign key constraint fails

I try to insert a new row into a table with the foreign key. But he doesn't want to, I think because he doesn't find the primary key. Though the primary key exists since I just added it.
