There is the place where the state tree is created and where it is provided the dispatch and subscribe methods. Our focus in this article will be the Redux core. This module connects the Redux core to react applications, creating HOC and Hooks that the react developers use to develop the UIs in the end. It consists of the core that handles the basic features, such as dispatch actions, update the store and notify the state updates.Īnother part is the bindings, the most popular one that is supported by the Redux core team is the React one, called react-redux. One important thing to understand here is the architecture of Redux. This updates the state using the reducer function and this new state returns to the application, updating the UI. You dispatch an action, that is a plain object, to the store. It is one of the first things that we learn when we start to study Redux. The data flow of Redux is the base of the library. It is not a tutorial and it requires a basic knowledge about Redux, the idea here is to understand the internals and not teach how to use. In this work, I did some notes, and this article is a more complete version of that.ĭisclaimer: This article tries to be a deep dive into Redux. Some time ago I decided to read the Redux codebase, to better understand the implementation of the library that I used in some jobs. Most of the developers use that, but did not know how it works behind the scenes. Redux is one of the most used state management libraries available today for web applications.
