7 Mistakes in React Native App Development with Solutions
When it comes to developing cross-platform mobile apps, React Native flashes in the minds of developers as the first and last choice. However, as with any technology, there are some challenges and benefits that come with React Native app development.
In this blog, we will explore common problems that developers face when they create a React Native app. Aside from that, you will become familiar with the 7 most common mistakes developers make in the creation of React Native apps, followed by their solutions.
Common Issues in Developing React Native Apps
Although there are many benefits that contribute to the rise of React Native app development, such as cross-platform compatibility, fast development cycle, cost-effectiveness, and the like, developing React Native apps may also have many challenges as well. These obstacles are listed below:
1. Problem in Integrating Native Modules:
When developers use advanced and platform-specific features, integrating native modules becomes challenging. Developers may need knowledge of native programming languages, such as Java and Swift.
2. Issue in Performance Optimization:
React Native may not work efficiently like native development for high-end apps that have complex animations or heavy computations. For such cases, developers need to fine-tune performances.
3. Limited Access to Native APIs:
React Native offers access to various device features. However, some native APIs may be unavailable. To cope with this problem in React Native app development, the developer needs to write custom native modules for access to particular functionalities.
4. Challenge in Version Compatibility:
React Native libraries and dependencies have frequent updates. Thus, compatibility between these updates and your current codebase can be problematic.
Most Common Mistakes in React Native App Development with Solutions
The following is a list of the most common mistakes that developers of virtually every React Native application development company commit:
1. Deviation from Protocols:
If the developer doesn’t stick to the most basic standards of React Native mobile app development, it will lead to terrible repercussions.
The whole development process will become slow if developers don’t follow the set protocols.
How to solve it?
This problem can be sorted out only if developers or designers always adhere to the best practices.
2. Negligence of Platform Differences:
With React Native, both React Native Android app development and iOS app development are possible for both platforms using a single codebase. However, not paying heed to platform-specific differences in UX/UI can result in inconsistencies and suboptimal user experiences.
How to solve it?
It’s a must-do for developers to focus on platform-specific design guidelines and tailor the UI/UX of apps according to them. If they use platform-specific code and test the app on both Android and iOS devices, they will get consistency and quality across platforms.
Taking into account platform differences and implementing platform-specific design elements, one can develop more cohesive and intuitive React Native apps.
3. Incorrect Estimation:

React Native allows code reusability and provides users with many reusable components. However, developers must know that page structure and app layout may be different across various platforms.
Therefore, it’s wise to examine the endpoints of the backend while creating web applications. As you will look after the app’s logic, make sure that everything is coded properly. It’s because you must have a crystal-clear idea of what you want to build for a correct cost estimation.
How to solve it?
When you prepare an estimate, consider the exact database architecture and plan for two separate layouts for your React Native app development.
4. Unoptimized Images:
Images can become a primary source of performance problems in React Native apps, as images are usually large files that need to be loaded from the disk.
How to solve it?
· You should use the correct image format, like using JPEG for photos and PNG for icons.
· Use caching, which will allow images to be loaded from memory rather than disk.
· Reduce the image size by using a tool, such as TinyPNG or ImageOptim.
5. Too Many Excessive ‘Console.log’ Statements:
Too much utilization of console.log statements in React Native applications can have negative implications on performance and maintainability. Each console.log statement adds processing overhead, which slows down execution and reduces the ability of apps to respond. In addition, too much logging clutters the codebase. After that, the codebase becomes harder to read and maintain.
How to solve it?
You should use console.log statements wisely for the necessary information, such as error messages or critical variables. Eliminate unwanted logs before deploying to production. Rather than depending on console logging, use debugging tools like React Native Debugger for better code traceability and more advanced features.
6. Negligence of External Module Code:
Not reviewing and understanding the code of external modules or libraries used in React Native app development can create problems. These issues are compatibility issues, limitations in customization, and security vulnerabilities. Unfamiliarity with the code of external modules may give birth to compatibility problems with the current codebase, security vulnerabilities, and limits in customization and extension possibilities.
How to solve it?
Properly read and understand the code of external modules, review documentation, and focus on implementation details. Verification of secure coding practices is a must-do. You should also ensure compatibility with the current codebase to prevent introducing bugs and errors.
When developers of an app development company get a clear idea of the code of external modules, they can make wise decisions, change modules if required, and optimize their usage to fulfill specific app needs.
7. Inability in Key Recognition:
It tends to happen that developers don’t recognize the key properly in React Native app development. In this case, if a list of items comes across any change, the React Native framework will re-render every time, which no React Native developer wants to happen.
How to solve it?
Allocate a special key to each list item, which will help you avoid any warning from the system in the future.
Key Takeaways
Common issues in creating React Native apps are problems in performance optimization, integrating new modules, limited access to fewer Native APIs, etc. The most common mistakes that happen in React Native app development are not optimizing images, deviation from protocols, inability to recognize the key, and so on.
