Function SystemMessage

Accessibility

  • The <SystemMessage>component is intended to be wrapped in a <BottomBarContainer> and placed inside the site <header> landmark to create the right reading order for screen readers
  • The component uses live region roles ("alert" or "status") so that the content is read automatically by screen readers as soon as it appears or is updated.
  • The live regions has an accessible label "Important messages" which can be overridden with the customTranslations prop.
  • SystemMessage(props, deprecatedLegacyContext?): ReactNode

  • Parameters

    Returns ReactNode

type Props = { name?: string }

const MyComponent: FC<Props> = (props) => {
  return <div>{props.name}</div>
}

MyComponent.defaultProps = {
  name: 'John Doe'
}

Deprecated

Use values for destructuring assignments instead.

OptionaldisplayName

displayName?: string

Used in debugging messages. You might want to set it explicitly if you want to display a different name for debugging purposes.

See

Legacy React Docs

Example


const MyComponent: FC = () => {
  return <div>Hello!</div>
}

MyComponent.displayName = 'MyAwesomeComponent'

OptionalpropTypes

propTypes?: WeakValidationMap<SystemMessageProps>

Used to declare the types of the props accepted by the component. These types will be checked during rendering and in development only.

We recommend using TypeScript instead of checking prop types at runtime.
