SQL Agent Web UI

A lightweight FastAPI + vanilla JS frontend for interacting with the SugarScale SQL agent.

Backend

Located at db_agent/ui/backend/main.py. It exposes:

• POST /api/query – wraps the existing agent pipeline (LLM + optional SQL execution + logging).
• GET /health – health probe.
• Serves the static frontend and index page.

Run locally

# Activate your virtual environment first
uvicorn db_agent.ui.backend.main:app --reload --host 0.0.0.0 --port 8000

The UI will be available at http://localhost:8000/. Adjust the host/port as needed.

Frontend

Files under db_agent/ui/frontend/:

• index.html – main page with the question form and results display.
• static/app.js – handles form submission, fetches /api/query, renders results.
• static/styles.css – modern styling.

Configuration Notes

• The backend reuses environment variables (DB_SERVER, DB_DATABASE, etc.) for SQL execution, so ensure they are set before starting the FastAPI server.
• The backend expects the LLM endpoint configured in db_agent/client.LlmConfig.base_url (defaults to http://192.168.0.30:8080). Update if your TGI server runs elsewhere.
• Interaction logs still append to db_agent/logs/query_log.jsonl by default.

Next Ideas

• Add user authentication or API keys.
• Save favorite queries or table presets.
• Stream results for large datasets.
