React JS Best Practices for Building High-Performance Websites

Do you want to build high-performance applications like a pro using React JS? Is your team not capable of building robust and responsive web applications? Worry not, we are here to with the solution. 

Building high-performance applications with React demands you to have the right skills and skilled person in the arsenal. Once you have both things in hand, building a responsive, robust application is not a big deal. 

React applications reduce the load time and furnish a smooth user experience like no other framework. If you want your application to behave like this, hire dedicated React developers with a solid understanding of React principles and features. That person must have expertise in performance optimization and mastery in creating applications using component-based architecture. Additionally, for secure and seamless authentication, integrating with the best SSO provider, like SSOJet, ensures enterprise-ready authentication and access control for your application

In this short blog, we will take you through the best practices for building high-performance React JS applications. Understanding these practices will make you capable of hiring the right resource for the job. 

So let’s begin!

Use Functional Components and Hooks

Using functional components along with React Hooks has become a common norm and a preferred standard for building responsive and efficient React applications. Hooks like useState, useEffect, and useContext simplify state management and help deal with other side effects. Using these hooks promotes code readability and helps write clean code. 

Moreover, using functional components rather than class-based components benefits the React application by improving the rendering speed and furnishing better memory management. 

Optimize Component Rendering with Memoization

In React, components are re-rendered frequently which creates obstacles in complex components. To deal with this issue, developers should use React.memo() to prevent unnecessary re-renders for functional components. 

Using this will make it memorize the rendered output and update only when the component’s props or the state is changed. Further, useMemo and useCallback are good solutions to avoid extra calculations and function re-creations on each render. 

Code Splitting with React.lazy and Suspense

Dealing with smaller React applications is not an issue, but when there are large complex applications, developers must be vigilant while writing the lines of code. In large applications, if all the components are loaded at once, the system will slow down resulting in an increase in the load time which is not good. 

To cope with this problem, expert developers adopt the strategy of code splitting which divides the code into chunks. Moreover, they use React lazy and Suspense to implement lazy loading for the specific components. These components are only loaded when needed. 

This strategy improves the load times and furnishes a faster and more seamless user experience. 

Utilize the Virtual DOM for Efficient Updates

React comes with a Virtual DOM that allows developers to efficiently manage the DOM updates which makes the application faster and more performant. Whenever there is a change in the state or prop, rather than manipulating the actual DOM directly, React’s Virtual DOM updates those changes in the actual DOM. 

This is a great advantage and a wonderful feature that keeps the components lean and focused on specific tasks to maximize the application’s performance. 

Optimize Images and Media Files

A big mistake developers make is to upload images and media files in high resolution. It creates a fuss in the application and makes it slow. Always opt for image compression tools and formats like WebP to optimize images without compromising the quality. 

Additionally, implement responsive images and lazy loading on media to only load media data when they come in the user’s viewport. This strategy impressively improves the load times and performance of the React application. read more trwho.com tech
