dal-web

name	dal-web
description	Work on the DAL web UI and backend. Use when starting or stopping the FastAPI/React app, changing `dal-web/`, running backend/frontend/e2e tests, applying the industrial terminal UI style, or enforcing async backend rules.

DAL Web

Overview

Use this skill for dal-web/ tasks: service startup/shutdown, backend FastAPI changes, frontend React/Vite work, Playwright smoke tests, persistence configuration, and the project's financial terminal UI style.

Start And Stop

Load and follow web operations for platform dispatch, startup, health and proxy checks, logs, graceful/forced shutdown, port-owner cleanup, persistence, and troubleshooting.

Tests

(cd dal-web/backend && uv run pytest)
(cd dal-web/frontend && npm run build)
./dal-web/scripts/setup-playwright.sh
(cd dal-web/frontend && npm run test:e2e)

Run Playwright when frontend/backend contract or user-facing flows change.

Backend Rules

Load and follow the complete backend style reference before changing FastAPI request paths, DAL extension calls, persistence, or external HTTP behavior.

Frontend Style

Load and follow the complete design system before changing the React UI or CSS. The style is data-dense, technical, dark, financial, and restrained.
