Redux Meaning Explained
Why it is Necessary to Use Redux?
There will be a time when react failed while transferring state between the components. As it is not easy to transfer data between the components, somewhat it is a little bit messy. It is hard to track all the data like from where it is coming from. For example, if someone is working on large and complicated apps then it will be going complicated to work.
Another problem which people mostly face was that unnecessary data was transferred to the components. Redux is recommended by all the people when the state is getting difficult to manage an application.
- Complete Separation of Data and Presentation: It looks little more than a presentation layer. In this, there is no concept of ‘state’ and known for ephemeral storage. If you lose anything on a new render then it will automatically go in React state when combined with Redux which in return gives you the best results that you would have ever imagined. At last, you will get complete separation of the state i.e. Redux’s concern and presentation i.e. React’s concern. You will reach to the top level React components to the subset of the data present in the Redux Store.
- Avoid Re-rendering: The main advantage is that you don’t have to concern about your own self whether it is the first time or something has been rendered before. As react rendering is considered as an immutable, both are handled in the same way whether it is a first render and the 100th render of the same component. Isn’t amazing? The main focus of the Redux is that it re-renders relevant components on the page. It is not a new concept for the users of frameworks such as Backbone or Angular as it is common for them as they might experience with re-rendering on data changes on the front – end. This is the reason why Redux is preferred by the people because it applies changes to the Virtual DOM and being successful in creating the smallest change set difference as possible which is generally applicable to DOM which is one of the lengthiest parts of the render process but in return, it will greatly improve performance. In short, you will never forget to render process in your entire life which has been true before in front-end.
- Server-Side Rendering: Single Page Application, SEO (Search Engine Optimisation) and page load times are some of the main problems. There would not have been a great solution for these problems. Many tried to allow some presentation reuse between server and client by using shared template files. With the help of React, a component library helps in rendering both in the browser with the help of DOM and to the HTML string which will be delivered by the server. This method is easiest with Node server because it is in the same language and mostly supports in most of the backend frameworks by running a Node server for React rendering exclusively on the side.
- DOM binding’s not a concern: All you faced the pain of binding DOM elements to functionality in the last five years in case you have written any front-end component whether it is with or without a framework. Redux helps you to handle the situation in the same way by splitting ac cross multiple code areas with single responsibilities.
As you have to face little pain in creating a single page application but Redux helps you in keeping away from many headaches in a long term. It provides the best way to write front-end code.
Hope this article helped you in understanding the Redux concept. The benefits are also discussed but finally, it is all up to you on how you are using Redux by keeping all the data in the store or use it with the local state only.
