11 Best React Native App Development Tips and Tricks
Some of the top React Native App Development Company in the USA follow these tips and tricks to build appealing apps.
Embrace the Power of Hermes Engine
To unleash the full potential of Hermes and React Native, take these essential steps: -Activate Hermes in your React Native project. This switch can speed up startup times and enhance runtime performance.
Optimize your code: Even with Hermes, efficient coding practices are crucial. Streamline computations and minimize DOM accesses for optimal performance.
Keep React Native up to current: By using the most recent version, you can maximise its benefits and assure compatibility with Hermes.
App Testing: After integrating Hermes and optimizing the code, it is imperative to do comprehensive testing and using profiling tools to detect and resolve performance issues.
While rendering avoid anonymous functions
In React Native, avoiding anonymous functions when rendering components is imperative. This practice is crucial for optimizing your app’s performance. A new function object is created each time a component renders if an anonymous function is defined inside the render method of the component.
This results in unnecessary re-renders, negatively impacting your app’s performance. To solve this issue, it is advised that you write your functions outside of the render method and provide them as props to your components. By doing this, the function object will only be generated once, avoiding wasteful re-renders and guaranteeing peak app performance.
Prevent using in-line functions
When using React Native’s inline functions as props for child components, the child component may needlessly re-render. This occurs because each time the parent component renders again, a new instance of the inline function is produced, causing the child component to render again even while its state or props remain unchanged.
Optimizing Images
High-quality photos may cause your program to become much larger and perform much worse. Including images often constitutes a substantial portion of an application’s load time. Image optimization through resizing, compression, and using the right formats can greatly improve performance.
In addition, integrating the FastImage library for image caching can improve the user experience by enabling smoother scrolling and rendering of images. . Optimizing these assets is crucial to ensure an effortless user experience.
Use Steady NPM packages
It’s important to choose smaller, more stable NPM packages for your React Native application. This reduces the size of your application and ensures efficiency due to its stable codebase. Please consider the following NPM website data while selecting the ideal package for your needs: Examine similar NPM packages available elsewhere.
Check the weekly downloads of the NPM package: A package with more weekly downloads is preferable.
Assess the size of the npm package: A more compact package will occupy less space in the project, ultimately reducing its overall size.
Look at the quantity of releases: More releases suggest that developers are actively maintaining their work.
Review the last update: This will help determine whether the package is still being maintained. Integrate these considerations into your package selection process. Hire a React Native developer to identify suitable, stable, and efficient NPM packages for your React Native project.
Avoid memory leaking
A memory leak occurs when a software program fails to release allocated memory (RAM) that is no longer required. Memory leaks can gradually cause a program to consume more memory, which could result in slowdowns or crashes as a result of running out of memory if they are not fixed over time.
Utilize Android Studio and iOS Xcode profiling tools to identify memory leaks within your applications. These techniques are intended to identify regions where memory usage is rising, although identifying the precise reasons can be difficult.
Detecting memory leaks in an application can be complex, so it is advisable to proactively keep the points mentioned above in mind to prevent memory leak issues. Detecting memory leaks in an app can be difficult, so it’s best to remember the above points to prevent memory leak issues.
Embrace a modular approach
Adopting a modular approach is crucial for success in React Native app development. You streamline development and elevate code maintenance by breaking your application into reusable modules. Benefits of the Modular Approach: – Enhanced code reusability – Clearer code structure comprehension – Streamlined debugging and maintenance
Accelerate Your React Native App with Higher Order Components
Higher-order components (HOCs) represent a potent feature in React Native, making a substantial contribution to optimizing app performance. These functions accept a component as input and return a new component with enriched capabilities.
By leveraging HOCs, developers can achieve code reuse, detach business logic from presentation logic, improve performance by minimizing unnecessary re-renders, handle authentication logic, and efficiently fetch data from APIs.
Reduce Application Size
To optimize your React Native app, consider using ProGuard to create different app sizes for various device architectures and compressing images. Adhere to the following best practices to minimize app and image sizes:
- The process involves transitioning components from the native environment to the React Native environment.

- Prioritize stability when using open-source libraries
- Opt for smaller PNG images and convert them to WebP format
- Utilize React NativeJS Thread and Navigator transitions
- Reduce CodePush bundle size by 66% using the .webp format
Reusability is crucial
When each component is dedicated to a single function, its usability is enhanced. This efficiency-enhancing approach saves developers time by repetitively eliminating the need to construct a new element for the same function.
Additionally, it facilitates project uniformity and encourages cooperation within the React Native community. It is vital to ensure project consistency and foster collaboration within the React Native community. Additionally, components must be concise and uncomplicated rather than bulky or intricate to facilitate seamless development.
Optimizing JSON to maximize React Native app performance
Mobile applications rely on fetching data from remote servers through APIs.
