The AssetOptions define how assets (images and other files) are named and stored, and how preview images are generated.

**Note**: If you are using the `AssetServerPlugin`, it is not necessary to configure these options.

```ts title="Signature"
interface AssetOptions {
    assetNamingStrategy?: AssetNamingStrategy;
    assetStorageStrategy?: AssetStorageStrategy;
    assetPreviewStrategy?: AssetPreviewStrategy;
    permittedFileTypes?: string[];
    uploadMaxFileSize?: number;
}
```

i.e. either a file extension (".pdf") or a mime type ("image/\*", "audio/mpeg" etc.).
