QueryView

Project skeleton: Python backend (FastAPI + SQLModel) + Vite + React + TypeScript SPA frontend with Tailwind CSS, plus Playwright end-to-end tests.

Layout

.
├── backend/         # Python FastAPI + SQLModel app exposing /api/* (queryview package)
├── frontend/        # Vite + React + TS + Tailwind v4 SPA (npm workspace)

Prerequisites

• uv — runs the Python backend and the Playwright (pytest) e2e suite (it manages the Python toolchain and dependencies for you).
• Node.js 20+ (with npm) — runs the root tasks and the Vite frontend.

npm runs the frontend and the root task scripts; uv handles the backend's and e2e suite's Python virtualenv and dependencies.

Install

Install the backend's Python dependencies (uv reads the root pyproject.toml; the package lives in backend/queryview):

uv sync

Install the JavaScript dependencies for the frontend workspace:

npm install

Install the e2e tooling (the test dependency group) and fetch the Playwright browser:

uv sync --group test
uv run --group test playwright install chromium

Run dev servers

Run backend and frontend together:

npm run dev

Or individually:

npm run backend    # uvicorn --reload on http://localhost:8000
npm run frontend   # http://localhost:5173

The Vite dev server proxies /api/* to the FastAPI backend, so the SPA can call the API on the same origin.

Build & preview production

npm run build      # produces frontend/dist/
npm run start      # SERVE_STATIC=1, FastAPI serves dist/ + /api on :8000
npm run preview    # build && start in one shot

In production there is no Vite — the FastAPI backend serves the bundled SPA from frontend/dist/ and falls back to index.html for any unknown non-/api path so client-side routing works. Override the dist location with STATIC_ROOT=/path/to/dist.

End-to-end tests

The e2e suite is pytest-playwright, installed via the test dependency group and run through uv.

Start the dev servers (npm run dev) in one terminal, then in another:

uv run --group test pytest

Override the target URL with BASE_URL=http://localhost:4173 uv run --group test pytest (e.g. to test a built preview). To run the full suite against a real ClickHouse the way CI does, use scripts/setup.sh.

Release to PyPI

The Publish to PyPI workflow (.github/workflows/publish.yaml, manual dispatch with a vX.Y.Z tag input) builds the SPA into the wheel (queryview/static/), then gates the release on the installed wheel: an HTTP smoke test, the packaged backend test suite (pytest --pyargs queryview), and the Playwright e2e suite driving the packaged server (skippable via the skip-e2e input for emergencies). It then publishes aaibina via PyPI trusted publishing, pushes the tag, and creates the GitHub release. The package version comes from the tag (no version bump in pyproject.toml).

An installed wheel serves the bundled UI by default:

pip install aaibina
aaibina            # API + SPA on http://localhost:8000

API

See docs/api.md for the full endpoint reference.

The single-page prompt UI is described in docs/queryview.md; connecting (new <type> / connect <name>), SQLite persistence, and session auto-connect are specified in docs/connect.md.

Connections are stored in SQLite (backend/queryview.db, override with DB_PATH); the backend writes that file and a local password-encryption key (backend/queryview.db.key, override with DB_KEY_PATH).
