The easiest option would be storing the error in Redux and showing the alert in componentDidUpdate when you detect that it has changed: componentDidUpdate (prevProps) { if (!prevProps.error && this.props.error) { // show the alert } } Another option is invoking directly the alert directly from redux-thunk (I'm assuming you're using it for handling the fetching). An even cleaner solution though (in my opinion) is achieved using something like redux-saga for triggering the side effect (the alert) when an error action is dispatched. P.S.: Let me know if you need any example of the suggestions above :)](https://hashnode.com/forums/thread/react-native-how-to-use-alert-api-in-redux-way/comment/57fea6d7e877cf5623d0438e) Comment · Thread · Oct 12, 2016 · 2 · [React Native : How to use alert API in Redux way?](https://hashnode.com/forums/thread/react-native-how-to-use-alert-api-in-redux-way) [Yep, Oceanic Next + One Dark](https://hashnode.com/forums/thread/what-is-your-current-atom-theme/comment/57faaf282212efbdcbc3f42a#reply-57fb3e05813841efc19c37ad) Reply · Thread · Oct 10, 2016 · 1 · [What is your current Atom theme?](https://hashnode.com/forums/thread/what-is-your-current-atom-theme) [Thank you for you post.
