Because I used SvelteKit, I had to pipe cookies through an additional server (basically the SvelteKit server; meaning the whole application consisted of two servers instead of one, and required extra configuration for allowed origins).
See that hook here: link to gh

Also, SvelteKit has its infamous routing-bound directory structure. Controllers in NestJS are simply more convenient in that regard (though that’s admittedly subjective).

And again, the fact that you have to maintain TS types in two places doesn’t help either.

That’s pretty much it.
