```javascript
import { createClient } from '@wix/sdk';
import { items } from '@wix/data';
// Import the auth strategy for the relevant access type
// Import the relevant host module if needed

const myWixClient = createClient ({
  modules: { items },
  // Include the auth strategy and host as relevant
});


async function truncate(dataCollectionId) {
  const response = await myWixClient.items.truncate(dataCollectionId);
};
```
