Understanding the Purpose of Middleware in Redux

In this blog post, we dive deep into the role of middleware in Redux, explaining its significance in the data flow of your application. We explore how middleware enhances Redux’s capabilities, enabling you to intercept, modify, or delay actions before they reach the reducers. Whether you’re a beginner or an experienced Redux user, this post will give you the clarity you need to harness the full potential of middleware in your Redux-based applications.

Introduction

In modern web development, managing state effectively is crucial for building scalable and maintainable applications.
