state

Static_stateFromProps

render

• render(): ReactNode

  Returns ReactNode

UNSAFE_componentWillReceiveProps

• UNSAFE_componentWillReceiveProps(nextProps: Props): void

  Called when the component may be receiving new props. React may call this even if props have not changed, so be sure to compare new and existing props if you only want to handle changes.

  Calling Component.setState generally does not trigger this method.

  This method will not stop working in React 17.

  Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.

  Parameters

  • nextProps: Props

  Returns void

  Deprecated

  16.3, use static getDerivedStateFromProps instead
