Firebase Studio

This is a NextJS starter in Firebase Studio.

To get started, take a look at src/app/page.tsx.

Environment variables

• JOKEHUB_JARVIS_USER_ID — Firebase UID that jokes added via POST /api/jokes/add are attributed to. Required; the endpoint returns a 500 if unset.

Deploying Firestore rules + indexes

The local firestore.rules and firestore.indexes.json are the source of truth. Two ways to push them:

• npm run migrations — migration 003-deploy-firestore-rules-and-indexes deploys both, using the same firebase-admin-credentials.json as every other migration. Runs once; for a later rules change, add a new 004-...ts migration.
• npm run firestore:push — ad-hoc deploy (or npm run firestore:push -- --check for a read-only diff of local vs deployed). Credentials come from FIREBASE_PROJECT_ID / FIREBASE_CLIENT_EMAIL / FIREBASE_PRIVATE_KEY (env or .env, same shape as src/lib/admin.ts) or fall back to firebase-admin-credentials.json.

Both are idempotent: in-sync rules are left untouched (and any push is verified by re-fetching the deployed ruleset), existing indexes are skipped. Index builds are async — dependent queries start working once each index leaves the BUILDING state in the Firebase console.
