How to Work with Redux-Thunk – Explained with Examples

Redux is a popular state management library for React and other JavaScript frameworks, which helps you to manage the state of your application in a predictable and consistent way. However, Redux alone does not support asynchronous actions, such as fetching data from an API, which are common in modern web applications. To handle asynchronous actions in Redux, you need to use a middleware, which is a function that intercepts and modifies the actions before they reach the reducers. One of the most widely used middleware for Redux is Redux-Thunk, which allows you to write action creators that return a function instead of an action object. In this blog post, I will explain how to work with Redux-Thunk, and how to create and dispatch asynchronous actions using Redux-Thunk.
