This is such a coincidence. I had the same idea a few days ago and also vibe coded a library using Claude. https://nindalf.com/books. The original version of this was meant to encourage me to read more, and I'm pleased to say it succeeded. I hit my goal for the year after a couple of lean years. I also like looking at my highlights and notes and this UI makes it easier to read them.
My experience with Claude was mostly very good. Certainly the UI is far better than what I'd come up with myself. The backend is close to what I'd write myself. When I'm unhappy I'm able to explain the shortcomings and it's able to mostly fix itself. This sort of small-scale, self-contained project was made possible thanks to Claude.
Other times it just couldn't. The validation for the start and end dates it decided was z.string().or(z.date()).optional().transform((val) => (val ? new Date(val) : undefined)). It looked way too complex. I asked if it could be simplified, Claude said no. I suggested z.date().optional(). Claude patiently explained this was impossible. I tried it anyway, it worked. Claude said "you're absolutely right!". But this behaviour was the exception rather than the rule.
