Redux will be briefly introduced, it’s core concepts explained, and then the focus will shift to applying those concepts from scratch on a simple use case. The aim of this article is to familiarise readers with Redux by building a Redux clone from the ground up, using the same API and general philosophy the library is built upon. It introduces actions, reducers, and stores, and uses those concepts to construct a fairly simple and effective state management architecture. ĭelegating the duty of state management to an external dependency imposes a new set of rules on the development process. ![]() When it comes to developing web applications, particularly on the client-side, Redux is currently the most popular state management solution. State management is an important part of application development, particularly in large-scale applications where client and server data needs to be orchestrated into a coherent and maintainable entity. The code presented in this blog post is available on GitHub. ![]()
