# Function: serverRouterHono()

```ts
function serverRouterHono<R, E>(router, options): MiddlewareHandler<E>;
```

Defined in: [hono.ts:67](https://github.com/simshanith/lit-ui-router/blob/740888c2b2ba358c4dfa52a122e927df6a604b12/packages/ui-router-server/src/hono.ts#L67)

Wraps a [ServerRouter](../../index/interfaces/ServerRouter.md) as Hono middleware. The returned handler resolves
the request to a verdict and either answers it (`return`ing the verdict
Response) or passes it on (`await next()`), exactly the fetch adapter's
`Response | null` contract expressed in Hono's continuation. Write the
router's type before the app's env (`serverRouterHono<typeof router, AppEnv>`)
so its delegate keys stay checked.
