Here, we are going to explore everything about React and its features and find out its React security, scalability, maintenance and performance.
What is React?
History of React
In 2011, Facebook faced a big challenge of handling a massive user base. It found that Document Object Model (DOM) is slow and they want to make it fast.
To face this challenge, Jordan Walke, one of Facebook’s software engineers created React. The team of facebook developers implemented a virtual DOM to make it fast and this is how React was invented. Later, it became easier for developers to build user interfaces with React.
Some Key Features of React
2. Virtual DOM (Document Object Model)
React offers Virtual DOM to increase your app’s performance. It takes the load on virtual memory and lets your app run smoothly.
3. One-way Data Binding
React is offering data in single-direction from top to bottom. It gives you complete control over the app and improves its performance.
React can make the app development process simple with its pre-built components. You can reuse these components while developing the app and keep the complexities minimum.
Here are some major reasons why React is most popular:
1. Small Learning Curve
Many developers found that the learning curve of React is so easy. You can start building apps right after clearing certain basic fundamentals. Furthermore, they have various resources and well-documented APIs available to increase the learning pace.
2. Pre-build Components Support
React offers various pre-built components that ease the overall app development process. Here, you need to simply pick the components and implement them while building your app.
3. Improve Performance
Thanks to React Virtual DOM, which can take load and shift to virtual memory to improve your app performance. Using React can help you to keep your app performance higher and provide seamless user experience.
4. Easy to Build Responsive Web Apps
React is offering components-based architecture that allows you to build responsive web apps with fewer complexities. Its libraries can help you to build mobile responsive user interfaces.
React is so versatile that you can use it to build a different range of apps including web, mobile and desktop apps. Many developers find React best-fit for making the development process easier and well-maintained.
React has VDOM and various APIs that keep detecting attacks such as XSS and preventing it. With React, you can regularly assess your web app interface and mitigate the risks.
React Scalability and Maintenance
React offers various pre-built React components in their libraries that you can reuse to build your web apps faster. Adding these components is so easy for developers that they can scale the app without affecting the performance. When most of the pre-built React components are used while building the app, React will ensure good performance.
Virtual DOM can help you to increase your app performance by reducing the load. It uses virtual memory to shift the load and ensure your app runs faster. It is a cross-platform where programming APIs deal with HTML, XML or XHTML. Having a virtual DOM makes the entire operation smoother and faster.
React Modularity and Reusability
React allows you to break your app’s interfaces into small React components. These components you can reuse anytime while building different apps. Such modularity and reusability for developers makes their app development process much easier.
Is the React Right Solution for your app?
Considering React is a great option. It has all the necessary features a developer requires to build a web app interface much faster. You can use their pre-built React components anytime while building your app interface. React is a widely used library, and its demand is also growing over time.
1. It uses JSX
2. Lack of Updated documentation
There are new tools and updates coming up every day in React. Because of these rapid changes, documentation gets outdated and affects the performance of applications.
3. Not Support SEO
React doesn’t support SEO, so you must have some expertise to optimize your app for search engines.
4. Fast Development Speed
React’s open-source community shares regular updates that affect the cycle of learning React.
Top 4 React Performance Optimization Techniques
1. Lazy Loading Images in React
If your React app consists of certain images, then it can slow down the app’s performance, as DOM faces the load of these images. That’s why, you should use lazy loading images to optimize your images and reduce the load to immediately load the photos without taking heavy rendering time. You can choose React-lazy load and React lazy load image component.
2. Server-side Rendering
Server-side Rendering is used to improve the SEO of your web app. But it also increases the load which slows down the performance. So first, you need to make sure whether you need SEO or not; if not then remove it. Else, you can consider NextJs as the lightweight and best server-side rendering. It helps you to keep the app performance optimized.
3. Avoid Anonymous Functions
Another effective way you should consider to optimize React performance is avoiding the anonymous functionalities. They keep rendering without any need to increase the load time. So you should create new memory each time to allocate the components that are Re-rendered.
4. Reduce Re-renders
Reducing re-renders is one of the best performance optimization techniques for the React software. It will help you minimize the unnecessary DOM updates caused because of the change in state or prop. However, re-rendering is a little costly method, especially when there are various child component updates.
There are various methods to minimize the re-renders, such as React.memo, shouldComponentUpdate, and PureComponent. You can use any of these essential techniques and methods based upon your needs and requirements to improve your application’s performance and responsiveness.
Examples of React-based Apps
Here are some popular examples of giant companies that used React for building their apps:
- Khan Academy
- WhatsApp Web
Frequently Asked Questions (FAQs)
Q.1 Is React Good for Scalability?
React is undoubtedly good for scalability because of its code splitting and efficient server-side rendering.
Q.2 What are some major React security concerns?
Some major React security concerns are cross-site scripting (XSS), cross-site request forgery (CSRF), broken authentication, unauthorized access, and handling user-generated content.
Q.3 What is Lazy Loading in React?
Lazy Loading is a react component that increases the web app loading speed and helps to load high-quality photos.
Q.4 Can React be used for server-side rendering (SSR)?
React uses for server-side rendering, especially with frameworks such as Next.js.
Q.5 How much time will it take to learn React?
You may take one to six months to become proficient in React and clear all the fundamentals.
React is a modern web development library which makes web development faster. But it’s important to – understand scalability, maintenance, React security, and performance to build an app. Now it’s your turn to hire dedicated reactjs developers and develop an app for your business.
