Redux middleware

Redux middlewares are functions that sit between the dispatching of an action and the point it reaches the reducer. They provide a way to intercept, modify, or enhance the behavior of Redux actions.

Middlewares in Redux enable developers to add custom logic and functionality to the Redux data flow, such as handling asynchronous actions, logging, analytics, or implementing side effects. When an action is dispatched, it passes through each middleware in the chain, giving them an opportunity to process the action or modify the data before reaching the reducer.

Middlewares can intercept actions, dispatch additional actions, or even halt the action dispatch altogether.

This extensibility allows for a flexible and scalable approach to managing application behavior and integrating external libraries or services into the Redux workflow.

Popular Redux middleware includes Redux Thunk for handling asynchronous actions and Redux Saga for managing complex side effects.
