# Dataflow UI

React + Vite + Tailwind CSS frontend for Dataflow.

## Development

```bash
npm install
npm run dev      # dev server on :5173, proxies /api to :3020
```

## Build

```bash
npm run build    # outputs to ../public/
```

The Express server serves `../public/` as static files — no separate web server needed in production.

## Key packages

- `react` / `react-router-dom` — SPA routing
- `@perspective-dev/client`, `viewer`, `viewer-datagrid`, `viewer-d3fc` — pivot table (npm, inline WASM builds)
- `tailwindcss` — utility CSS
- `sql-formatter` — SQL display formatting
