Whether we are scrolling through our phones, navigating a website, controlling the car displays, or even using the controllers of our thermostats, it is the user interfaces that make up our experience on the screens. Digital displays on the black screens are all around us and constitute the majority of our online experience. In order to make the users stay and engage with the interface, it is imperative that businesses focus their attention on developing an amazing user interface or UI. A great way to make your user interface more intuitive and easy-to-navigate are by integrating it with React and Redux. What are React and Redux and what are their benefits in UI of your application or product development? Keep reading to know more.
What is React?
What is Redux?
Redux keeps the state of the application in store and each component can access any state that it needs from this store.
How can React be used and what are its benefits?
React is a way to build user interfaces. It is only concerned with the front-end. React makes user interfaces very easy to build by cutting each page into pieces. We call these pieces components.
- Putting Components Together: We can put React components inside other components. This is how a page can be built.
Why should React be used?
The following are some of the reasons why React should be used:
- Reusable Components: React provides a component-based structure. Tiny components like button, checkbox, dropdown etc., can be used to create wrapper components composed of those smaller components. And then higher-level wrapper components can be written. And, it goes on like that until you have this one root component and that component is your app.
- Clean Abstraction: One of the powerful sides of React is that it provides a good abstraction which means that it does not expose any complex internals to the user. A basic understanding of a component’s life cycles, states, and props are needed to master React.
- Redux: It is a kind of reinterpretation of flux architecture. It provides a single store which is not required in flux. There is only one single object where you keep all the application data. This makes it easier to observe and manipulate.
Why should Redux be used?
Understanding how Redux works:
There is a central store that holds the entire state of the application. Each component can access the stored state without having to send down props from one component to another.
There are three building parts: actions, store, and reducers.
- Actions in Redux: Actions are events. They are the only way you can send data from your application to your Redux store. The data can be from user interactions, API calls or even form submission. Actions are sent using the store.dispatch() method. As pure functions, they do not change the data in the object passed to it or perform any side effect in the application.
- Store in Redux: The store holds the application state. There is only one store in any Redux application. You can access the state stored, update the state, and register or unregister listeners via helper methods. When using Redux with React, states will no longer need to be lifted up, hence it makes it easier for you to trace which action causes any change.
Other benefits of using Redux:
- Redux makes the state predictable: In Redux, the state is always predictable. If the same state and action are passed to a reducer, the same result is always produced as reducers are pure functions. The state is also immutable and is never changed. This makes it possible to implement arduous tasks like infinite undo and redo.
- Maintainability: Redux is strict about how code should be organized so it makes it easier for someone with knowledge of Redux to understand the structure of any Redux application. This generally makes it easier to maintain.
- Debuggable for days: Redux makes it easy to debug an application. By logging actions and state, it is easy to understand coding errors, network errors and other forms of bugs that might come up during production.
- Ease of testing: It is easy to test Redux apps as functions used to change the state of pure functions.
- Redux can also be used for server-side rendering: With Redux, you can handle the initial render of the app by sending the state of an app to the server along with its response to the server request. The required components are then rendered in HTML and sent to the clients.
