Performance issues in React Web Development are nothing new and developers have been dealing with them. So, whenever a new language is introduced, they run into many performance concerns and one such language is React. It has a fast DOM – fast to a point where it renders the hierarchy with many components that are useless. Therefore, causing User Interface issues that lead to the developers not being willing to use the language. However, there are many ways that the performance of React can be optimized. Let’s look at them!

6 Ways You Can Optimize Your React Web Development Performance

React is a user interface library that is written in JavaScript. It comes with several options to reduce the number of DOM operations that consume time but are required for refreshing the User Interface. For many web apps, using React results in a fast experience without the requirement of optimization. However, in some, it is the opposite – and that is where strategies for improving the performance of React are put to action. Keep on reading to find out 5 optimization techniques.

1.      Use React.Lazy & React.Suspense For Lazy Loading Components

When it comes to improving the performance of React, applying the lazy loading technique helps. The basic idea behind this technique is to load the components only when it is needed. Luckily, the framework React comes loaded with React.Lazy API so that the developers get a dynamic import as a regular component.

So, instead of loading the components like : import LazyComponent from ‘./LazyComponent’; the developers can reduce the risk by using the lazy way and render the component: const LazyComponent = React.lazy(() => import(‘./LazyComponent’));.

Technically, this React. Lazy takes functions that call a dynamic import and return promises which resolve a module with default export. Moreover, it contains a react component. Apart from that, the lazy component is rendered within a suspense component, which allows adding fallback content as the loading state while developers wait for the lazy component to load.

2.      Use The Production Build

While testing the performance of React Web Development, make sure to test using the minified production build if you are having reacter performance of benchmarking issues. React as a framework does come with several useful warnings that are there by default, and they are also very useful for development.

However, these warnings and alerts make React slower and bigger. So, make sure that while deploying the project, you use the production version. And, in case you are not sure if the build process is correctly set, use the React Developer Tools in Chrome for checking.

3.      Use React.memo For Component Memoization

Another great way to optimize the performance of React web App Development is using React.memo because it helps the functional cache components. In simple words, it is a technique that speeds up the programs of computers by caching the expensive function call result. It also returns the result that is cached when identical inputs are encountered repeatedly.

Thinking how does this actually work? Whenever any function is rendered using this tactic, it saves the results in the memory and the next time a function with a similar argument is called, the saves result-saving bandwidth is provided.

Let us make it more clear to understand. Arguments and functional components in React are props. Hence, when a function is rendered by using React.memo technique, results are preserved in memories and returned when a function with a similar parameter is raised. Therefore, conserving bandwidth.

4.      Flat List Optimization Using React-Window

One of the easiest techniques to tune up the performance of React after having invested in Web Development Services. It is used for rendering never-ending lists of data or a table with massive data. In fact, it can significantly slow down the performance of apps. In such a situation, virtualization can help – thanks to the libraries like React Windows. They help in solving the problem by only rendering the items visible in the list currently, allowing the rendering of any size of the list.

5.      Avoid Using Multiple Chunk Files

Web or mobile apps on React always start with some elements and you can add new dependencies and features to the system quickly. But, this results in a huge production file. To avoid such a situation and optimize the performance of your React Create App, consider using CommonsChunkPlugin for webpack. It will segregate the third-party or vendor library code from the application code – making two files as a result. These two files are cached less by the browser and resources are retrieved in parallel, which reduces the load time.

6.      Dependency Optimization

Analyzing how much code is being used from the dependencies when optimizing the React application’s bundle size is good. For example, you might be using Moment.js offering multi-language localized files. But if you do not need support for several languages, remove the unnecessary locales from the final bundle using the moment-locales-webpack-plugin. Taking the case of loadash, where you are using only 20 of the 100+ available methods, having all the other approaches is not ideal. Do it by removing the functions that are not needed with the loadash-webpack plugin. From there, download the dependencies list that is to be optimized.
