🛠 Getting Started

Follow these steps to set up the application locally.

1. Backend Setup

# 1. Create a Python virtual environment
python3 -m venv venv

# 2. Activate the virtual environment
# macOS/Linux:
source venv/bin/activate
# Windows PowerShell:
.\venv\Scripts\Activate

# 3. Install Python dependencies
pip install fastapi uvicorn pydantic PyMuPDF cryptography PyPDF2

2. Database Setup (Prisma)

# Push your Prisma schema to the database
npx prisma db push

# Generate the Prisma client
npx prisma generate

Tip: Ensure your .env contains the correct DATABASE_URL before running these commands.

3. Frontend Setup

# 1. Install Node dependencies
npm install

# 2. Copy or create a .env file
cp .env.example .env

# 3. Run the Next.js development server
npm run dev

4. Run Services

• Start FastAPI:

  uvicorn main:app --reload

• Open Frontend:
  Navigate to http://localhost:3000 in your browser.
