Firebase configuration

This app expects Firebase configuration to be provided in firebase-config.js and loaded before script.js.

1. Copy firebase-config.js and replace the placeholder values with the config from your Firebase project:

   window.FIREBASE_CONFIG = {
     apiKey: "YOUR_API_KEY",
     authDomain: "YOUR_PROJECT_ID.firebaseapp.com",
     projectId: "YOUR_PROJECT_ID",
     appId: "YOUR_APP_ID"
   };

2. For environment-specific values, keep different firebase-config.js files per environment (local, staging, prod) and swap them during deployment, or have your hosting pipeline inject the correct values.

Firebase setup steps

1. Create a Firebase project in the Firebase console.

2. Enable Authentication: go to Build → Authentication → Sign-in method and enable Email/Password.

3. Create Firestore: go to Build → Firestore Database and create a database in your preferred region.

4. (Optional) Create Realtime Database: go to Build → Realtime Database if you plan to use it.

5. Deploy security rules:

   • Firestore rules are in firestore.rules.
   • Realtime Database rules are in database.rules.json.

   Using the Firebase CLI:

   firebase deploy --only firestore:rules
   firebase deploy --only database

Data structure expectations

All user data is written beneath a users/{uid} path, matching the security rules. The app currently writes:

• users/{uid} (user metadata such as encryption salt)
• users/{uid}/fastingState/state (encrypted app state)

Ensure your rules continue to allow only the authenticated user (request.auth.uid) to read/write their own data.
