The video explains how to set up and use asynchronous action creators with network requests in a Redux application.

Summary

  • The tutorial begins by stating the prerequisites of having state actions and reducer set up from the last video.
  • Two npm packages, Axios for API calls and Redux Thunk as middleware, are installed and configured in the Redux store.
  • An asynchronous action creator function, 'fetchUsers', is created which uses Axios to make API requests and dispatches actions based on the API response.
  • The process of making an API request using Axios and dispatching actions for request success and failure is demonstrated.
  • The video concludes with a terminal demonstration of the asynchronous action creator's effect on the Redux store's state.
