Hello and welcome to another interesting and full of knowledge blog about React. We all know React is a powerful and popular JS tool that builds dynamic and highly interactive web applications. But what some of us don’t know is how to optimize the performance of a React application.
Worry not as this blog is equipped with 10 proven tips that will optimize the performance of your React web application and ensure a smooth user experience along with faster loading times.
The only thing to mention before we get to our main topic, if you are facing persistent issues with your React application’s performance, hire dedicated React developers to professionally handle the issues.
Let’s get to today’s topic!
- Implement Lazy Loading
Lazy loading itself tells its meaning that it allows to loading of the components slowly. When you implement lazy loading in the React code, it only allows the application to load the components that are necessary at that moment. This strategy improves the performance of the application.
- Use Production Build for Deployment
You can optimize the performance of your application by using the production build for deployment. Using production for deployment removes the unnecessary code from the application and optimizes it with better speed, and by making it faster and smaller.
- Prevent Unessential Renders
Avoiding unnecessary renders is another tip that optimizes the performance of web applications. You can prevent such renders by adopting methods like memoization, or by ensuring props and state are handled efficiently.
- Optimize Images
It is the common practice to upload images with high resolution on the website neglecting speed and performance. Upload images after compressing with proper sizes. Moreover, implement lazy loading for media as it will elevate the site performance.
- Optimize Large Lists and Tables
There are applications with large data sets, like extensive lists and tables. Rendering everything at once can be a greater setback for the performance. Virtualization is a technique that only renders the visible portion of the list or table. This helps increase the performance of the application.
- No Inline Functions
There must be no inline functions as it leads to unnecessary re-renders of the child components. Instead, declare the functions outside the render method as React won’t re-render such components.
- Keep Component State Local When Necessary
Don’t overuse the global state. Overusing the global state is also a reason for the low performance of the application. Keep utilizing the local state as it prevents re-renders and improves the overall performance.
- Reduce the Component Depth
Build components that are not excessively deep rooted. Deeply nested components create performance challenges by increasing the rendering time. So, try to keep the components less deep to keep up the speed of the application.
- Optimize the Network Requests
Another factor that leads to hindering the performance is not able to handle the network requests efficiently. Optimization of network requests is extremely important as it reduces the load times and elevates the overall performance of the application.
Opt for batching and caching to optimize the network requests. Both techniques will enhance the performance while managing multiple network requests.
- Implement State Management Strategies
State management plays a vital role in making the application’s performance up to the mark. Using Context API or Redux will reduce the unnecessary re-renders. Moreover, use the setState method to update the batch state; it will also improve performance.
Conclusion
Building a React application is an easy task but keeping its performance according to the standards is the key thing. Following the above 10 proven tips to elevate the performance of React applications will help you in this regard. Implement these techniques and make your application stand out. Moreover, an application with better performance guarantees better customer engagement and conversion rates. So, implement your strategies carefully, and don’t forget to elevate the application’s performance.
