Common Use Cases of Middlewares
- Logging: Middleware is frequently leveraged to record actions and their subsequent state alterations. Developers can establish middleware functions to document details such as action type, payload, and modified state, facilitating debugging and comprehending app dynamics.
- Asynchronous Operations: Despite Redux’s inherently synchronous nature, middleware empowers the management of asynchronous activities, including API requests. Middleware frameworks like Redux Thunk or Redux Saga simplify the distribution of asynchronous actions, enabling developers to retrieve data from servers or trigger side effects before distributing future actions.
- Authentication and Authorization: Middleware can monitor actions associated with authentication and authorization processes. For instance, middleware can verify user authentication prior to specific actions.
- Caching: Middleware allows for the implementation of caching, where frequently accessed data is stored for faster retrieval. The middleware intercepts data retrieval actions, checks if the data is already cached, and avoids making network requests for cached data. This technique enhances performance by reducing the need for repetitive data retrieval.
What are middlewares in React Redux ?
In the world of creating websites and apps, React and Redux are powerful tools used to build apps that can grow and be easily updated. React helps build user interfaces, while Redux helps keep track of the app’s data in a way that makes it easy to understand. Redux uses something called “middlewares” to control how actions, that change the data, are handled.
In this article, we’ll learn what middleware is and how it makes it easier to manage data in React Redux applications.
