Connect to Firebase

Firebase lets you sync across devices and collaborate in real-time using a shared room code — no accounts needed.

1

Create a Firebase project

Go to console.firebase.google.com → Add project → disable Analytics → Create.

2

Add a Web app & copy config

Project Overview → </> Web → register → copy the firebaseConfig object.

3

Enable Firestore

Build → Firestore Database → Create → test mode → any region → Enable.

4

Paste your config

Paste exactly as shown — the full const firebaseConfig = { … } block works fine.

Sync & Collaboration

Firebase is not connected. Set it up to use sync and rooms.

Current Room

Share this code to collaborate

Create a new room

Anyone with the code can view and edit events in real-time.
