  Request handler that wraps the whole response body in `meta` for requests with
  `options.isMetaRequest` set.

#  MetaDocHandler

```ts
const MetaDocHandler: Handler;
```

Defined in: [-private/handlers/meta-doc.ts:51](https://github.com/warp-drive-data/warp-drive/blob/48dc0d277b98008082669dadc6a52e5c5682ef8e/warp-drive-packages/utilities/src/-private/handlers/meta-doc.ts#L51)

MetaDocHandler processes requests that are marked as meta requests.

It treats the response body as "entirely meta" transforming

```ts
{
  some: "key",
  another: "thing"
}
```

into

```ts
{
	 meta: {
    some: "key",
    another: "thing"
  }
}
```

To activate this handler, a request should specify

```ts
options.isMetaRequest = true
```

For instance

```ts
store.request({
  url: '/example',
  options: {
    isMetaRequest: true
  }
});
```

Errors are not processed by this handler, so if the request fails and the error response
is not in {json:api} format additional processing may be needed.
