3/22/2023 0 Comments Redux thunk![]() Before moving further, I'd like to dig into what is type aliases first. The TypeScript's type aliases is used here. The definition of ThunkAction can be overwhelming and filled with generics(defined with ). ![]() Let's dive in head-on then by looking at the type definition of ThunkAction. I will be explaining how type aliases are being used in a more complex type definition. However, if you're interested in learning TypeScript's type aliases, I think you would enjoy this blog post as well. Hope you've check out the materials recommended above before you continue reading □ □ I also highly recommend reading what is a thunk. Most Redux apps have the thunk middleware enabled, but the default Dispatch and bindActionCreator types only know about the standard behavior of a basic. Then, come back to this blog post to learn about the TypeScript definition of ThunkAction. Redux Toolkit's RTK Query data fetching API is a purpose built data fetching and caching solution for Redux apps, and can eliminate the need to write any thunks or reducers to manage data fetching. If you're not sure what redux-thunk is, I'd recommend reading through the why do I need this section in the redux-thunk library. Let’s see how Redux works without middlewares.This blog post will be focusing on explaining the TypeScript definition of ThunkAction which is used in the redux-thunk library. (For logging, crash reporting, async tasks, etc.) Provides a 3rd-party extension point between dispatching an action and the moment it reaches the reducer. Again, here is the question: What is the Redux middleware? Here is the answer: Then you should know how to work with them. Redux Middlewaresīut sometimes you work on a project that they’re using a Redux middleware. Actually, I prefer using react-query since it gives you a lot of features like caching, retrying, etc. ![]() Maybe I can give Redux the response of the query. For me handling an async task with react-query is sometimes the best option. But why do we need Redux middlewares for async tasks? You may suggest react-query only, which is still a valid response. I think it’s mostly because of that word thunk. You may now ask, okay let’s use the Redux. But seriously: Redux Thunk is a really confusing thing when you first hear about it. But Redux gives you a more structural and advanced way of doing state management. Finally, Redux Thunk and friends is just one possible approach to asynchronous requests in Redux apps. redux-thunk Public Thunk middleware for Redux TypeScript 17.5k 1.1k redux-devtools Public DevTools for Redux with hot reloading, action replay, and customizable UI TypeScript 13.3k 1.1k redux-toolkit Public The official, opinionated, batteries-included toolset for efficient Redux development TypeScript 9. We can simply use context API in order to share the data. You may say that okay why do we need Redux? Alternative ways Imagine in one part of an application (let’s call it a component) you have a counter and in another part, you want to show the result of that counter as well. But before going through it, we should first understand why do we need them?Īs you know, Redux is a library for global state management. Today we’re going to discuss Redux middlewares for async tasks.
