React Native has revolutionised mobile app development by offering a cross-platform solution without compromising the user experience. However, building a successful app is not just about launching a beautiful and functional product. It also requires ensuring that the app’s performance is top-notch. In this comprehensive guide, we’ll explore why React Native app optimisation is crucial and how app development company in Birmingham applied best practices to implement them for peak performance.  

Understanding React Native Optimisation  

Optimising React Native apps is not just a methodology; it’s a necessity. The performance of an app can significantly impact user retention rates and the success of a product. Apps with sluggish interfaces or slow load times are often uninstalled or abandoned, resulting in lost revenue and a damaged brand image. Therefore, it’s important to understand the fundamental principles of optimisation and how they apply to React Native.  

Best Practices for Optimising React Native Apps  

To ensure your React Native app stands out for its performance, consider the following best practices:  

Code Optimisation 

Minification and Bundling  

Minification reduces the size of your JavaScript bundle by removing unnecessary whitespace, comments, and other non-essential characters. This practice is essential for improving app load times, especially on slower networks.  

Implementing Virtualized Lists  

Virtualized lists only render the items that are currently visible on the screen, which significantly improves the memory and overall performance of the app, especially when dealing with large datasets.  

Image and Asset Optimisation 

Using Proper Image Formats  

Selecting the right image format can reduce file sizes. For instance, using PNGs for images with transparency and JPEGs for photographs can help maintain quality while minimising the space they occupy.  

Caching Strategies  

Utilising a robust caching strategy can improve performance by loading assets from the cache where possible, reducing the number of requests to the server, and ensuring a smoother user experience, especially in offline scenarios.  

Network Optimisation 

Minimizing Network Requests  

The fewer requests your app makes, the faster it will perform. Bundle resources, use image sprites, and consider prefetching commonly used data to minimise network calls.  

Implementing Data Caching  

Persist data locally in the app’s storage to eliminate the need for frequent network requests. Tools like AsyncStorage or SQLite can help cache critical data.  

Testing and Profiling  

Performance Testing Tools  

Leverage tools like Lighthouse, PageSpeed Insights, or GTmetrix to test your app’s performance under various conditions and get suggestions for improvements.  

Identifying and Resolving Bottlenecks  

Once profiling has highlighted the areas of concern, work on resolving the detected bottlenecks by optimising code, managing network requests better, and ensuring efficient use of app resources.

With a focus on React Native, a cross-platform framework renowned for its performance and efficiency, Inforox adopted a systematic approach to development, adhering to the following best practices:  

Here’s how Inforox implemented optimisation techniques tailored to the client’s app:  

Code Optimisation  

By meticulously reducing unnecessary characters, comments, and whitespace, Inforox significantly decreased the app’s JavaScript bundle size. This streamlined the loading process, which is particularly beneficial for users on slower networks. We integrated virtualized lists, allowing the app to render only the visible items on the screen. This optimisation drastically improved memory management, especially when handling extensive datasets.  

Image and Asset Optimization  

We selected appropriate image formats, opting for PNGs for images with transparency and JPEGs for photographs. This strategy- maintains image quality while minimising file sizes.  

Network Optimization  

We reduced the app’s reliance on network requests by bundling resources, employing image sprites, and prefetching commonly used data, thereby improving overall performance.  

Testing and Profiling  

We utilised tools such as Lighthouse and PageSpeed Insights to comprehensively test the app’s performance under various conditions, ensuring it met high standards. As a leading app development company in Birmingham, we diligently addressed identified bottlenecks by optimising code, refining network request management, and ensuring efficient resource allocation, resulting in a finely tuned React Native app for their automotive client in Birmingham.  


The collaboration between Inforox and the automotive client culminated in the successful development and deployment of a feature-rich mobile application. The app seamlessly integrates with the client’s existing systems, providing users with a comprehensive suite of functionalities, including:  

Vehicle tracking and management  

Maintenance scheduling and reminders
