PM builds a web card game with Claude Code and shares pitfalls

What to do

Check service worker live reads and App Check settings if Claude Code builds a PWA with Firebase.

Why

The PM reports that App Check blocked bot traffic and that service workers caused live read problems.

What the research found

A product manager describes building the Yapt conversation card game as a PWA with Claude Code, using React, Vite, Firebase Firestore, Retool as a low-code CMS, and PostHog, and notes practical pitfalls with service worker live reads and App Check blocking bot traffic and Claude's tooling.

Claims and how well the evidence supports them

Yapt uses React and Vite with Firebase Firestore for card prompts 99%
Retool is used as a low-code CMS linked to Firebase 99%
App Check was enabled to stop bot traffic and it also blocked some Claude tooling 95%
The app is deployed as a PWA at yaptcards.com 99%
