Defaults to `"app"`, falling back to the default export. - `indexHtml`: Path to the HTML document template, resolved relative to the Vite root. Defaults to `"index.html"`. ### `AskrServerPlugin` ```ts AskrServerPlugin: any ``` Portable public identity for the server integration plugin. - `name`: readonly name: "askr:server"; ### `composeAskrDocumentResponse` ```ts composeAskrDocumentResponse: (response: Response, transformedDocument: string, options?: AskrDocumentOptions) => Promise ``` Compose an Askr fragment response into the full `transformedDocument` HTML, streaming the fragment's body between the document prefix and suffix. Non-fragment responses are returned unchanged. ### `composeAskrHead` ```ts composeAskrHead: (document: string, head: string, lang?: string, dir?: string) => string ``` Replace the {@link ASKR_HEAD_MARKER} in `document` with normalized `head` markup, and patch the `` tag's `lang`/`dir` attributes when given. ### `createDocumentApp` ```ts createDocumentApp: (app: ServerApp, transformedDocument: string, options?: AskrDocumentOptions) => ServerApp ``` Wrap `app` so every response is composed into `transformedDocument` via {@link composeAskrDocumentResponse}. ### `insertAskrFragment` ```ts insertAskrFragment: (document: string, fragment: string) => string ``` Replace the single {@link ASKR_APP_MARKER} in `document` with `fragment`. ### `isAskrFragment` ```ts isAskrFragment: (response: Response) => boolean ``` Whether `response` carries the `askr-fragment=1` content-type marker. ## Documentation navigation [Previous](https://askrjs.com/docs/reference/api/vite/root/index.md) | [Next](https://askrjs.com/docs/reference/api/vite/image/index.md)
