7 Tips How To Optimize React Native Performance

React Native Performance

Do you use React Native software for developing applications? Are you searching for ways to Optimize React Native Performance?                           

Below this blog, we have briefly discussed primary techniques to optimize React Native performance.

Before we head on, ensure that you have installed the React Native software and that it’s properly working. 

Explain How It Optimizes React Native Performance?

Let us take a little glance at what React Native is and how it operates so that you can acknowledge the optimization techniques flexibly.

React native is a UI software system developed by meta platform in 2015, an application building software for android, ios, and many more platforms. It uses javascript and native code for creating apps.

Knowledge of javascript would be enough for using React-native. IOS and android codes are not required to be learned if you use React Native.

Some renowned apps based on React Native software and offering great platforms to businesses, creators, and others are Facebook, Instagram, Pinterest, skype, etc.

Javascript and native code used in React Native can’t communicate with each other directly, and they use shadow trees to do so. The shadow tree is a standard connector in the middle of native and javascript codes and delivers serialized JSON attributes from the native to the javascript line.

React native, the best software across the platform for application creation also comes with issues and technical glitches that can be corrected with some techniques.

Now, let us dive deep into the top performance optimization tips and hacks for React Native.

Calibrate The Size Of the Picture

People like to insert pictures in their applications to make them look attractive. Because of this, they sometimes load the apps with a bulk of images of high resolutions and start facing problems, for instance, slow image loading, lagging due to over usage of storage, and much more. 

The solution to this issue is a timely inspection of images, graphics, and content so that they are not bulked up, and if this happens, trash bin those high-quality files and cache memory.

The above-given tips will help you boost your React Native application speed and enhance the experience.

A person should employ React Native software to make the perfect picture size adjustments while creating cross-platform apps.

Developing IOS And Android Application To Its Perfect Size

While developing an application for Android or IOS by React Native, the coder should ensure that the app size should be optimum, i.e., not too bulky. Otherwise, it will affect the app’s processing speed and make it slow in carrying out the task.

The best way to cut down the app size is to include only those features and components that are must-haves for the app and optimize them to help maintain a perfect application size.

Another way of doing this is to fix a Proguard to reduce app size.

Implementing React Native Driver For An Enhanced Viewers Encounter

The app creator builds applications using React Native, applying animations and effects to enhance the users’ experience and take away. 

But if these animations and effects are not downloaded effectively, they can lead to poor app creation and performance.

To solve this problem of poor performance. An effective Run After Interactions method of Interaction Manager should be adopted to provide your users with the best and most enhanced app performance.

This method will ensure that the animations and the Reactdriver are working smoothly and provide the best user interference to the users with performance optimization.

Refrain From Needless Renders

It is confirmed that React Native uses various processes running in the background, causing performance and processing speed to slow down.

To pinpoint those non-essential processes, we suggest you use Xcode, an incredible way to remove unnecessary renders and contribute to optimizing the performance.

Xcode will also help you detect unwarranted storage leaks and offer you the report to manage those leaks and supply high-speed performance. Also, it will help you provide low storage usage.

Make Use Of Important Sign-On List Items

Every app uses some list items so to save Reactfrom rendering. Allocating a critical key or sign to each list item will stop Reactfrom re-rendering whenever someone adds or removes an item from the list.

Unique keys to these list items will make React Native, separate them from each other, and provide high-speed optimized performance to the users.

It is one of the techniques to optimize React Native performance effectively.

Implementing Necessary Features Only

Using necessary features and removing all unnecessary features will add to the fast load time of the app. Unnecessary features, animations, and items will consume more app storage hence adding to long loading and processing time.

Features found to be essential and required to carry out the work through the app should be given more preference over those that will only add to the memory and are of no use.  

Applying essential features means more accessible storage, leading to speedy processing and optimizing React Native performance.

Using Numerous Chunk Files

When creating an application, you always try to add maximum features to provide your users with a great experience. 

But by doing this, the file size gets so huge that a time comes when you need to trim down some features.

Here, what if I say you can have all the features? Yes, it is possible by separating your file.

You can use CommonsChunkPlugin to do this. 

Dividing your file will contribute to fewer browser caches and reduce the app load time. 


In a nutshell, React Native is a software that uses javascript for developing applications for android and IOS. It is very popular worldwide. But every good thing has some drawbacks, and React Native also comes under this.

React Native sometimes faces challenges in processing speed, overutilization of the storage, etc.

So, to overcome these problems, we have discussed the above seven best techniques to optimize React Native performance.
