When it comes to streamlined and flawless web application performance, many front end developers prefer ReactJS. As it offers amazing features and user interface designs. In this scenario, using React JS Development Company services, you can build faster and reliable apps. Developers can simply manage the code issues. It has virtual DOM to render components, it’s still possible to come across performance issues in medium to large web applications using various ReactJS Tools.
In this blog, we will let you know how to optimize web application performance along with sharing latest tools and best practices. In addition, you will also learn how a few JavaScript best practices also help to make your web app deliver fluent user experience.
How Does ReactJS Work?
Before moving ahead, we need to learn how the framework works. Well, ReactJS is a JavaScript-based library providing Virtual DOM to developers. Using ReactJS, it is easy to create an effective hierarchy of UI functions. Thus it will help to deliver an amazing user experience.
React follows a tree-like structure for UI components. Therefore, each component has functions rendered to users. React keeps track of each user’s request and interaction with the system. Thus if you make any changes, then it compares them with the old UI and re-renders the UI with changes that are required despite the whole UI.
React offers faster development with the support of virtual DOM. Thus, many companies and big organizations are opting ReactJS development services over others.
Top Reactjs Tools to Optimize Your ReactJS App Performance
1. Using React.PureComponents
With JavaScript, variables can be modified. These variables are the basis for programming functions. When the React component renders the same output on every state of variables, it’s considerably pure. Thus, ReactJS comes with component class and is known as React.PureComponents.
With ShouldComponentUpdate, it allows control of the function automatically. If the states and props are similar from the last rendering then they are considered as pure components. This means such components will know whether the states are the same or not. If they are the same, it will not re-render for updates.
2. Immutable Data Structures
Immutable data is not a design pattern. It’s an opinionated way of building code. This way, it is easy to structure the application data flow. In short, data immutability is a method that revolves around a strict unidirectional data flow.
Immutable data can be implemented to the design of front-end apps. You can get several benefits including:
- Zero side-effects
- Easy to create, test, and use
- Avoids temporal coupling
- Easy to manage changes
When it comes to React Native App Development Company, they maintain the internal state of components, and changes to the state can cause the component to re-render.
React builds an internal representation of the rendered Virtual DOM. When there are some changes in components, React compares the old and new UI. And when they are not equal, React will update the DOM.
3. Using React.Suspense
When a user sends a request for an image or video, occurs a time lag. But with React.Suspense, you can represent feedback to users that there will be a time lag. Thus the screen freezes during the lag, it allows users know what’s coming and can ensure user engagement.
Here, you can use the code for React.Suspense.
// MyComponent.js
const MyComponent = React.lazy(()=>import(‘./component.js’))
function App() {
return (
<div>
<Suspense fallback={<div>loading ..</div>}>
<MyComponent />
</Suspense>
</div>)
}
Wrapping Up:
So, if you are developing a ReactJS app, without the support of a professional ReactJS development company is a big mistake. To craft and deliver a feature-rich customer experience, you need to hire reactJs developer for smooth development.
So, if you wish to track all the updates, variables, and components, then choose the suitable and perfect optimization ReactJS Tools for app development. These tools certainly help an app perform faster and boost business.
