# Backend integration

The bundled Demashi JSON remains the default so the reusable template can start without backend credentials. Deployments can switch all 29 pages to the independent backend without changing page components by injecting configuration before the Angular bundles load:

```html
<script>
  window.__SAAS_VOC_CONFIG__ = {
    domesticDatasetMode: 'api',
    domesticVocPath: '/api/domestic-voc',
    domesticWorkspaceId: 'demashi'
  };
</script>
```

API mode requests only:

```text
GET /api/domestic-voc/snapshot?workspaceId=demashi&platform=jd
```

Local `ng serve` forwards `/api/domestic-voc` to `http://127.0.0.1:4400`. Fmode and database credentials remain server-side.

The API response must keep the `DomesticDataset` contract in `src/app/core/models/domestic.models.ts`. Missing reviews remain an empty array and must not be replaced by inferred VOC output.
