WalkthroughThe notification components now have TypeScript implementations with Flow compatibility. They define typed constants and public exports, support localized dismissal and icon variants, render notifications through an accessible portal, and update tests and Storybook stories. ChangesNotification component migration
Estimated code review effort: 3 (Moderate) | ~25 minutes Mergeability Score: 🔵 Low · up to The migration preserves runtime behavior but weakens an accessibility regression test and may expose an inaccurate public TypeScript props contract for consumers. The PR is mergeable with explicit owner awareness or follow-up on these bounded issues. Possibly related PRs

Restore the aria-live assertion.
wrapper.props() is always truthy for this rendered Portal. This assertion no longer verifies the required polite live region.
Assert wrapper.prop('aria-live') equals 'polite'.
Proposed fix
- expect(wrapper.props()).toBeTruthy();
+ expect(wrapper.prop('aria-live')).toBe('polite');📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

react-intl 6.6.8 injectIntl TypeScript declaration InjectedIntlProps public component props
💡 Result:
In react-intl version 6.6.8, the type InjectedIntlProps is not available [1][2][3]. It was removed and replaced in earlier major versions (starting from v3) [1][2]. If you are attempting to use injectIntl with TypeScript, you should use WrappedComponentProps instead of InjectedIntlProps [1][2]. To correctly type a component wrapped with injectIntl: 1. Define your component's own props interface (e.g., MyComponentProps) [2]. 2. Extend your props interface with WrappedComponentProps (which provides the intl prop) [1][2]. 3. Apply this interface to your component [2]. Example usage: typescript import { injectIntl, WrappedComponentProps } from 'react-intl'; interface MyComponentProps { someCustomProp: string; } const MyComponent = ({ someCustomProp, intl }: MyComponentProps & WrappedComponentProps) => { return <div>{intl.formatMessage({ id: 'someId' })} - {someCustomProp}</div>; }; export default injectIntl(MyComponent); For modern React applications using react-intl, it is recommended to use the useIntl hook instead of the injectIntl higher-order component, as it provides a more straightforward way to access intl context without requiring complex type wrappers [4].

Export public props without intl.
NotificationProps is re-exported, but injectIntl(Notification) supplies intl. Separate the internal props type from the exported public props type.
