Working with Redux: Pros and Cons

Blog Authors | Board Infinity

Today, over 2159 companies actively use Redux, including Amazon, Instagram, and Robinhood. Redux is an open-source state management library widely used for JavaScript applications. In layman’s terms, it is a sort of a pattern that helps manage and update the application state using simple events named ‘actions’.

Developed by Andrew Clark and Dan Abramov in 2015, Redux is compatible with various frontend frameworks, including React, Vue, and Angular. This data-flow architecture has gained popularity in the past six years. However, just like two sides of a coin, Redux's pros and cons are debatable and without ample knowledge of the same, you may not be able to utilise it to the best capacity. Let us discuss it in detail below.

What is Redux?

As discussed above, Redux is a popularly known open-source JavaScript library that facilitates state management in applications. It is compatible with React, Vue, and Angular. However, it is most commonly used with React.

Redux is said to be an upgraded or better version of Flux. It is because it has eliminated the unnecessary complexities in Flux architecture. If you are pursuing top front-end development projects, being well-versed with Redux will serve as an added benefit. Therefore, developers can make the most of this library by taking Redux advantages and Redux disadvantages into account. Let us learn more about it!

State Management with Redux: A Look at the Pros

There are multiple advantages of Redux that have made it a popularly used state management tool in today’s market. Although the most prominent benefit is improved state management, there is much more to it. Let us learn about Redux's advantages.

1. Increases the Predictability of a State

In the Redux library, a state is invariably predictable. Since reducers are pure functions, they always produce the same result when the same action or state is passed to them. Also, in Redux, every state is immutable. So, developers can perform burdensome tasks easily by implementing infinite redo and undo.

2. It is Highly Maintainable

Understanding the structure of any Redux application is quite easy for developers who have in-depth knowledge since code organisation is strict in this library. Therefore, for large applications that go through frequent updates, Redux is highly useful.

3. It Prevents Re-renders

When a state changes in Redux, it returns a new state which often uses a shallow copy. So, the probability of re-renders is reduced substantially. If you are preparing to become a front-end developer, then you must learn how to make the most of Redux to reduce re-renders.

4. Redux Optimizes Performance

One of the prime benefits of Redux is that it optimizes the performance of large applications. It is highly effective in persisting the state of a given component even after it gets unmounted. Many other performance optimizations are internally implemented with Redux which also enhances component re-renders.

5. Makes Debugging Easier

Debugging an application is easy and pretty simple with Redux. Developers who have used it claim that the DevTools available with it allow many time-travel actions effectively. It is also easier to understand and identify network errors, coding errors, and other types of bugs that might affect the system during production.

6. Useful in Server-Side Rendering

The usefulness and effectiveness of Redux in server-side rendering are also well-proven. Handling the initial render of an application is quite easy with Redux. It is one of the advantages of Redux that makes it more preferable to developers than other state management libraries.

7. Provides Ease of Testing

Redux applications are easy to test since developers can use functions to change the state of well-defined pure functions.

All these Redux advantages make it one of the most widely used tools in recent times. If you have started learning the best Java programs for beginners, then you should move ahead with your learning curve and master Redux as well. It will help you get through the learning process and make the most of your knowledge.

State Management with Redux: A Look at the Cons

On the other side of the coin, you have a few Redux disadvantages that developers have identified over the years. Here are the most frequently identified drawbacks of Redux.

1. Lack of Encapsulation

There is no possibility of encapsulating any data in the Redux library. So, the chances of security issues grow as an application becomes heavier with new components. Since there is no data encapsulation, any component can access it.

2. Restricted Design

Most developers have complained about the rigidity of Redux. It is very restricted with minimal alternatives. So, you can use it for a trivial application or anything of that nature as state management will become more complex than it is without Redux.

3. Excessive Memory Use

In Redux, every state is immutable. In order to update a state, a reducer has to return a new state every time. This process creates compilation in the long run leading to excessive memory usage.

4. Increased Complexity

Even though the benefits are plenty, Redux has an additional complexity in layering when it comes to using manipulation logic actions or reducers.

5. Time-Consuming

For small or medium-level local state management, Redux can be highly time-consuming as it requires more inputs of the boilerplate code to begin writing.

Importance of Mastering Redux to Developers

Redux has become a mainstream state management tool in the market, especially for companies that run consumer-facing applications. Its compatibility with different frameworks also increases its reach to different platforms. Here is why it is an important skill that developers should acquire.

  • Redux is compatible with most of the commonly used frameworks, like React, Vue, and Angular.
  • It is an in-demand skill since the e-commerce market is growing rapidly and generating job opportunities for developers skilled with this tool.

Therefore, developers must master Redux if they want to become full-stack development experts. The full-stack development course by Board Infinity helps you learn the nitty-gritty of numerous frontend and backend frameworks, including React, which requires the use of Redux the most. Learning Redux with other best software development programming tools may help you the most in your career.

The Final Say

The use of Redux as a state management tool is a kind of trade-off. It introduces indirection, complexity, and constraints to a code that requires in-depth knowledge of this tool and the frameworks it is compatible with. Developers who have mastered Redux can tell when to use it and when not to. This way, it becomes easier to overcome Redux's disadvantages to a great extent! Also, for developers who are yet to implement this tool, it is essential to keep all these factors in mind before utilising it.
