Lately  one among the most important debates within the frontend world has been about this subject called “Redux”. Not long after its release, Redux became one among the most well liked topics of dialogue for people. Many favored it and started using it while others pointed out issues on it.

So today I’m gonna tell you about REDUX and is it really that big a deal for front-end developers?

What is REDUX?

Before telling much about redux first we should know what redux actually is? So,It is an open-source library of JS (JavaScript) mainly used for managing the state of your application . It is most ordinarily used with libraries like React or Angular for building user interfaces. Similar to Facebook’s Flux architecture, Redux may be a predictable state sometime but it’s container designed to assist you to write JavaScript apps that behave consistently across client, server, and native environments and are easy to check .While it’s mostly used as a state management tool with React, you’ll use it with the other JavaScript framework or library. So you don’t need to worry about it making your application’s asset size bigger.With Redux, the state of your application is kept in a store, and every component can access any of the parent state that it needs from that above stored state.

When to use REDUX?

Redux allows you to manage your app’s state during a single place and keep changes in your app more predictable and traceable.It makes it easier to explain changes happening in your application . But all of those benefits accompany tradeoffs and constraints. One might feel it adds up boilerplate code, making simple things a touch overwhelming; but that depends upon the architecture decisions.

One simple answer to the present question is you’ll realize for yourself once you need Redux. If you’re still confused on whether you would like it, you don’t. This usually happens when your app grows to the size where managing app state becomes a hassle; and you begin searching for creating it easy and straightforward .

REDUX  is most useful when it used in test cases like-

  •  You may have a large amount of application state which is needed in many places in the application itself.
  •  The app state is updated frequently
  •  The logic to update that particular state may be complex sometimes
  •  The app has a different size code base (medium or large-sized codebase) depending upon requirement, and might be worked on by many people.
  • You need to see how that state is being changed over time to time. 

What is state management ?

Till  now you have heard the word state management so what does it actually mean, and what does it mean in redux terminologies?

State management is actually how to facilitate communication and sharing of knowledge across components. It creates a tangible arrangement to represent the state of your app that you simply can read from and write to. That way, you’ll see otherwise invisible states while you’re working with them.

Most libraries, such as React, Angular, etc. are built with components to internally manage their state with no need for an external library or tool. It does well for applications with few components, but because the application grows bigger, managing states shared across components becomes a chore.

 Why to use REDUX?

In an app where data is shared among components, it’d be confusing to truly know where a state should live. Ideally, the info during a component should sleep in only one component, so sharing data among sibling components becomes difficult.

Why to use REDUX?

The main reason why we should use redux is that the component does not need to provide any state or method for its children components to share data among themselves. Everything is handled by Redux. This greatly simplifies the app and makes it easier to take care of .

Some of the other reason like-

  • Redux makes the state predictable.
  • Redux is maintainable.
  • Redux makes debugging easy
  • Redux can also be used for side server rendering.
  • Easy on testing.
  • Performance benefits.


So  in conclusion I would like to add that, though we have discussed the major features of Redux and why Redux is beneficial to your app. While Redux has its benefits, that does not mean you need to set about adding Redux altogether to your apps. Your application might still work well without Redux. One of the  advantages of using  Redux is it gives you a feature like direction to decouple on your app. However, you ought to only implement Redux if you identify your project needs a state management tool.
