# trade-visualizer

Standalone local frontend (Vite + React) for the `trade` stack.

## Dev (proxy to VPS)

Default target is `https://trade.mpabi.pl`.

```bash
npm ci
npm run dev
```

Optional env:

- `API_PROXY_TARGET` (default: `https://trade.mpabi.pl`)
- `GRAPHQL_PROXY_TARGET` (default: same as `API_PROXY_TARGET`)
- `VITE_API_URL` (default: `/api`)
- `VITE_HASURA_URL` (default: `/graphql`)

The dev server proxies:

- `/api/*` to the upstream API
- `/graphql` + `/graphql-ws` to upstream Hasura (supports WS subscriptions)
- `/auth/*`, `/whoami`, `/logout` to upstream UI (session auth + cookie rewrite for localhost)

## 100% local

Point proxy to your local `trade-frontend` container:

```bash
API_PROXY_TARGET=http://localhost:8081 GRAPHQL_PROXY_TARGET=http://localhost:8081 npm run dev
```
