Investigation of replacing the online-Firebase dependency during local development with the Firebase Local Emulator Suite (Auth, RTDB, Storage), including required env vars, proposed emulator config, conditional useEmulator() wiring points for client SDK and firebase-admin, and known blockers (service account file read at SSR startup, external HK content API). https://claude.ai/code/session_0143398zobwdf7EVfSh84iS6
Lets the app run fully offline against the Firebase Emulator Suite (Auth, RTDB, Storage) with permissive local-only rules and no real credentials, while prd/acc/dev keep using real Firebase untouched. - firebase.emulator.json + emulator/ rules (open .read/.write, local only) - .env.emulator with demo- dummy config; env.js resolves it when USE_FIREBASE_EMULATOR=true or when no .env.<NODE_ENV>.local exists - conditional useEmulator() wiring in src/firebase.js (client + SSR) - conditional firebase-admin init in src-ssr/api/index.js; the service account file is now read only in non-emulator mode, fixing a dev-server startup crash when the key file is absent - emulators / ssr:emulator npm scripts + firebase-tools devDependency Verified end-to-end: emulators boot, SSR homepage renders (200), auth routes redirect, and an Auth-emulator token is accepted by the admin SDK which then reads RTDB - all with no real credentials.
Browser sign-in failed with auth/network-request-failed because the useEmulator() calls used "localhost": on dual-stack machines localhost resolves to IPv6 ::1 first, but the emulators bind IPv4 only, so the browser could not reach the Auth emulator. Pin client useEmulator() hosts and the admin FIREBASE_*_EMULATOR_HOST vars to 127.0.0.1. Verified via firebase emulators:exec: email/password signUp + signIn both return 200 with an idToken, and RTDB read/write succeed on 127.0.0.1.
