Easiest Guide To Understand Redux

In recent times, the JavaScript library Redux has gained immense popularity when it comes to building user interfaces.

In this piece of information, we will be reading more about Redux to gain a clear and complete understanding.

Just like React, Redux follows a strict and one-way data flow. This is one of the best advantages since all data in an application then follows the same lifecycle pattern that makes the application logic easier to understand and more predictable. Moreover, this facilitates normalization of data so that you don’t have to end up with multiple and independent copies of the same data that are unknown to each other. The path for data updation in the store follows the exact flow every time when store updates are necessary, irrespective of the source of the update (either from data getting fetched from a REST API or the user inputting data into a form).

In addition to these unique advantages, Redux is also beneficial to save valuable time during the process of development as you can retain state of the application or “hot-reload”. Hot reloading is the unique ability to reload code parts automatically when a file is saved, without you being required to refresh the full page.

Reloading of Redux-connected components stimulates immediately reading of the existing data from the Redux store and thereafter rendering the data with the updated code. This gives you the unmatched ability to “live-edit” the user interface to speed up the development process.

In Redux, the use of “pure” reducer functions makes the logic easier to test. Moreover, this use enables beneficial features such as “time-travel debugging”. If that is not all, predictable state updates make it smoother and easier to understand the working of the flow of data in an application. Centralizing the state also makes it an easy affair for implementation of things such as persisting data between page refreshes or logging changes to the data.
