The application consists of a frontend (static HTML/JS) and a backend (FastAPI), with the following main components and flows:

1. GET /

   • Serves the main index.html file for the chat interface.
   • Response: FileResponse

2. POST /chat

   • Handles incoming chat messages.
   • Request Body: { "message": string }
   • Response: StreamingResponse (Server-Sent Events)
     • Streams AI-generated responses back to the client.

3. GET /api/health

   • Performs a health check on the API.
   • Response: { "status": string, "message": string }

1. Frontend loads:

   • Client requests the root URL (/).
   • Backend serves the index.html file.

2. User sends a chat message:

   • Frontend sends a POST request to /chat with the message.
   • Backend receives the message and forwards it to Ollama.
   • Ollama processes the message and generates a response.
   • Backend streams the response back to the frontend using Server-Sent Events.
   • Frontend displays the streamed response to the user.

3. Health check:

   • Client or monitoring service requests /api/health.
   • Backend responds with the current health status.
