Async actions in bare Redux with Thunk or custom middleware

This article explores managing asynchronous actions in Redux by discussing two main approaches: using Thunk middleware and creating custom middleware. It highlights the challenge of maintaining Redux’s synchronous state management while integrating asynchronous tasks, and suggests splitting asynchronous actions into three synchronous phases: start, success, and failure. The Thunk middleware allows for defining actions as functions to handle business logic and side effects, while custom middleware can isolate HTTP request logic for cleaner action creators. The article contrasts the simplicity of Thunk with the scalability and maintainability of custom middleware, also mentioning Redux Toolkit’s createAsyncThunk API for streamlined asynchronous action handling.
