This guide will cover some of the ins and outs of Redux while also giving some insight into how it is effectively used in a development framework. While this guide isn’t going to serve as a how-to on where to implement it, it should hopefully give you a few notions of why this tool is useful for your web development work.
How Does Redux Work?
So, now that you have a working definition of the technology, it helps to understand how things actually work. As you’ll find through the rest of this guide, this will be more of a general bird’s eye view of the technology rather than an in-depth exploration of how it works.
How it is used beyond this simple implementation is what makes the methodology rather compelling to use in your applications.
An entire application state can be stored in the global container system used by Redux. While this might not seem terribly exciting on the surface, it has far-ranging implications for how you manage an application. A simple action can be stored and recalled at any point in time, giving a predictable and reliable way of implementing state changes. This isn’t a complicated endeavor either, as you’ll see in the next section.
The core principle about what makes Redux so immediately usable is its usage of something reducers. Now reducing commands and actions is nothing new in programming. However, when you go to initiate an action like a login button being pressed, you have to write far less code to achieve the same effect.
Now, you could potentially have stored the exact variables and actions needed in a container for this very occasion. You’re still doing the same thing with the containers in Redux. You have far less input needed to achieve the same effect. Reducers retrieve the current state of the application and return a new state. It uses minimal code to affect a change across states.
How Redux Is Used
There are a few different methods of use for Redux, which you’ll find in its documentation. This will be a very high-level overview of its implementation.
First and foremost, Redux is a store of data. Containers are useful for storing variables and other data points. After all, you might need to recall the various mechanisms of an application. Using it solely as a container is a fairly mundane use of the technology, but a useful one nonetheless.
Applications are complicated affairs, with numerous moving parts to yield the best result. Storing common variables in a container is a great way to call upon that data as needed across an application.
Arguably the most useful feature of Redux is in how it approaches state management in an application. You’re more than likely going to need to make constant changes to an application as you’re running tests or simply using it. Having a reliable and predictable way to apply universal state changes across all components is extremely useful.
You’re going to be changing states on a fairly regular basis in any application. After all, applications are rarely static. Redux gives a simple and effective means of managing and enacting state changes on an application as a whole.
Why Should You Use Redux?
Better Management of Applications
Think about your last application, and think hard about how the various components in use. Did you need to store multiple common variables across each component of the application itself? If you find yourself answering yes, then Redux could very easily benefit you.
It isn’t going to be the ideal solution for every project you work on. However, familiarizing yourself with the toolkit is going to boost productivity. That doesn’t even mention the fact that you have easily manipulated containers that allow you to affect state changes with minimal input. In fact, once you get things configured and learn the process with the toolkit, it should be an absolute breeze to use.
Uniform Changes Across Applications
It cannot be understated how massive it is to create uniform and predictable state changes across an application. Redux takes what can be a relatively complicated, yet necessary process, and takes a lot of the legwork out. The end result is a powerful and flexible way to boost your productivity while developing.
It also serves some great benefits when looking at things like developing bespoke storefronts, sign-up forms, or anything else where there is a fair amount of tedium to get the required results. Simply put, it only serves to benefit developers who have steady workloads.
Is Redux Important for Modern Web Development?
So, is Redux important for modern web development? Yes, to put the answer succinctly. It might not be as revolutionary as the likes of Node or React in terms of popular frameworks. However, there is something to be said about technology that helps take the load off the programmer and simplifies certain processes.
