VeritasAI Dashboard + FastAPI Backend

This project now includes:

• A Vite + React frontend in the repository root
• A FastAPI backend in backend/

Frontend Setup

1. Install dependencies:

```bash
npm i
```

2. Start the frontend:

```bash
npm run dev
```

The frontend reads VITE_API_BASE_URL and defaults to http://127.0.0.1:8000.

Deploy Frontend To Firebase Hosting

This repository is preconfigured for Firebase Hosting with:

• firebase.json (serves dist/ and rewrites SPA routes to index.html)
• .firebaserc (default Firebase project: veritasai-6e4ac)
• npm script: deploy:hosting

1. Set production API URL (required):

```bash
cp .env.production.example .env.production
```

Edit `.env.production` and set:

```bash
VITE_API_BASE_URL=https://your-backend-domain.com
```

2. Login to Firebase CLI:

```bash
npx firebase-tools login
```

3. Deploy hosting:

```bash
npm run deploy:hosting
```

4. If you want a different Firebase project, switch it before deploy:

```bash
npx firebase-tools use --add
```

Firebase Setup

Firebase app + Cloud Firestore are initialized in src/app/lib/firebase.ts.

Optional Vite environment variables:

• VITE_FIREBASE_API_KEY
• VITE_FIREBASE_AUTH_DOMAIN
• VITE_FIREBASE_PROJECT_ID
• VITE_FIREBASE_STORAGE_BUCKET
• VITE_FIREBASE_MESSAGING_SENDER_ID
• VITE_FIREBASE_APP_ID
• VITE_FIREBASE_MEASUREMENT_ID

If omitted, the app uses your provided Firebase config values.

To use Google sign-in/sign-up, enable Google as a sign-in provider in Firebase Console:

• Firebase Console -> Authentication -> Sign-in method -> Google -> Enable

Backend Setup (FastAPI)

1. Create and activate a Python virtual environment.
2. Install backend dependencies:

```bash
pip install -r backend/requirements.txt
```

3. Run the API:

```bash
uvicorn backend.main:app --reload --host 127.0.0.1 --port 8000
```

Backend Firestore Persistence

FastAPI persists users and analysis history to Firestore when Firebase Admin credentials are available.

Configure one of the following before starting backend:

• FIREBASE_SERVICE_ACCOUNT_PATH (path to Firebase service account JSON), or
• GOOGLE_APPLICATION_CREDENTIALS (Application Default Credentials).

Firestore collections used by backend:

• users
• analysis_history

If credentials are missing or invalid, backend falls back to in-memory storage.

Connected Input Flows

The following user inputs are connected to FastAPI endpoints:

• Login form (/api/auth/login)
• Signup form (/api/auth/signup)
• Text analysis input (/api/analyze/text)
• URL checker input (/api/analyze/url)
• Image upload (/api/analyze/image)
• Video upload (/api/analyze/video)
• History view (/api/history)
