AI Chat Application

This project consists of a React frontend with TypeScript (using Vite) and a FastAPI backend.

Frontend

The frontend is built using Vite with React and TypeScript.

To run the frontend:

cd frontend
npm install
npm run dev

Backend

The backend is built using FastAPI.

To run the backend:

1. Install the required Python packages:

   cd backend
   python -m venv venv 
   source venv/bin/activate
   pip install -r requirements.txt

2. Set up the PostgreSQL database:

   • Install PostgreSQL if not already installed
   • Create a new database for the project
   • Update the .env file in the backend directory with your database credentials:

   DATABASE_URL=postgresql://your_username:your_password@localhost:5432/your_database_name
   

3. Add your OpenAI API key:

   • Update the .env file in the backend directory
   • Add your OpenAI API key:

   OPENAI_API_KEY=your_openai_api_key_here
   

4. Run the database setup script after updating the database name in the setup.sql file:

   psql -d your_database_name -f backend/setup.sql
   

5. Add a secret key to your .env file:

   • Generate a secure random string to use as your secret key. You can use a tool like OpenSSL:

     openssl rand -hex 32

   • Add the generated secret key to your .env file:

     SECRET_KEY=your_generated_secret_key_here
     

   Replace your_generated_secret_key_here with the actual key you generated.

6. Start the backend server:

    uvicorn app.main:app --reload
   

Running the Application

To run the application, start the backend and frontend servers:

cd backend
uvicorn main:app --reload

cd frontend
npm run dev

Open your browser and navigate to http://localhost:5173 to access the application.
