# client.demo

> The landing page's live latency demo.

The landing page's live latency demo.

Reach it as `client.demo` on a [`QumoClient`](https://docs.qumo-deploy.com/sdk/reference/client#qumoclient).

### createSession

```ts theme={null}
createSession(options?: { signal?: AbortSignal }): Promise<DemoSession>
```

Starts a demo session: a broadcast path of its own and a short-lived
credential to publish and subscribe to it. It needs no account, and
sends nothing of the caller's.

It throws an `APIError` with status 404 when the deployment has no demo
configured, 429 when there have been too many sessions (from this
address or in all), and 5xx when one could not be started.

Types: [`DemoSession`](https://docs.qumo-deploy.com/sdk/reference/types#demosession)
