  +### Transient mode
  +
  +Provide the `transient` flag and it won't cause new render passes, instead you will be notified through the `onAction` callback. This works the same for Hoc's, render-props and hooks.
  +
  +```jsx
  +const [handlers] = useGesture({ transient: true, onAction: e => console.log(e) })
  +```
