With over 1.6k active contributors working to make React Native a success, the framework’s bright future has caught the attention of developers eager to excel in the cross-platform world.

The rising demand for React Native app development is not solely due to the growing industry but also the constant updates that make the framework more advanced. However, mastering React Native requires understanding the common pitfalls that can ruin user experience and hinder a developer’s growth.

In this blog, we’ve divided the content into four sections to help you understand and avoid React Native app development mistakes, ultimately improving your skills.

Why Do Developers Love React Native?

1. JavaScript-Friendly Environment

React Native leverages JavaScript, a language that most developers are already familiar with. This reduces the learning curve significantly and allows developers to transition smoothly into React Native development.

2. Native-Like Application Building

Unlike web views, React Native renders real native components, providing a platform-specific feel. This allows developers to create smooth and interactive applications with native-like performance.

3. Simple Installation Process

React Native can be easily installed through Node Package Manager (NPM), which is especially convenient for developers with JavaScript backgrounds. Even those unfamiliar with JS can avoid the hassle of downloading binary files from the source.

4. Boosted Productivity

React Native’s live reload feature and the flexibility to use any IDE or text editor enhance productivity. Developers can make real-time changes and see the results instantly.

5. Strong Community Support

Since its launch in 2015, React Native has gained immense popularity. A strong community of developers constantly works on enhancing the framework and resolving issues.

6. True Cross-Platform Capability

React Native isn’t limited to mobile apps. Developers can expand their skills to build apps for smart TVs, smartwatches, Windows devices, and even VR headsets.

Challenges Associated with React Native App Development

1. Dependency on Native Developers

For heavy computational tasks, JavaScript limitations force developers to offload work to the native side, requiring collaboration with native developers.

2. Abstraction Layer Issues

Adding more functionality to React Native apps often requires an abstraction layer, which can lead to:

• Difficulty in identifying bugs.
• High dependency on third-party libraries.
• Challenges in implementing custom designs.

3. Lack of Support for Parallel Threading

React Native operates on a single JavaScript thread, causing performance issues when executing multiple processes simultaneously.

4. Complex iOS Deployment

Testing iOS apps on platforms other than Apple’s TestFlight is cumbersome due to issues with provisioning profiles and certificates. In contrast, Android deployment is smooth and hassle-free.

Common React Native App Development Mistakes

1. Wrong Estimation

• iOS and Android layouts differ significantly, requiring accurate estimation.
• Forms and backend logic need careful validation.
• Database structure and entity connections must be well understood.

2. Poor Redux Store Planning

Redux is powerful for managing app data but is more suited for large-scale applications. Using Redux for small projects can lead to unnecessary complexity.

3. Ignoring External Module Code

External modules save time, but developers must read the code to understand potential issues and compatibility problems.

4. Mutating State Inside the Render Function

Directly mutating the state corrupts the component’s lifecycle, leading to abnormal app behavior and performance issues.

5. Leaving “console.log” Statements

While useful for debugging, leaving console.log statements in the production code can slow down the app, especially for asynchronous functions.

6. Not Using Pure Components for Performance

Using PureComponent instead of Stateless Component prevents unnecessary re-renders and boosts performance, especially in complex UI apps.

7. Failing to Optimize Images

Optimizing images by resizing them locally and using cloud storage like S3 for CDN links speeds up image loading and enhances performance.

8. Skipping Unit Testing

Skipping unit tests can lead to functionality issues that are only discovered post-launch. Writing thorough unit tests ensures a smooth app experience.

9. Not Following React Native Protocols

Adhering to best practices and protocols is essential for maintaining code quality and avoiding bugs.

10. Ignoring Project Structure

A well-organized project structure prevents confusion and makes the codebase easier to manage and scale.

How to Become a Mistake-Proof React Native Developer

A. Continuous Learning

Enroll in React Native courses to enhance your skills and stay updated with the latest advancements.

B. Work with a Company that Prioritizes Training

Join a mid-sized company that offers mentorship and hands-on experience with practical projects.

FAQs About React Native App Development

Q. How can I improve React Native performance?

• Avoid unnecessary re-renders.
• Use PureComponent instead of Stateless Components.
• Optimize JSON data handling.
• Reduce app size.

Q. Why use Redux with React Native?

Redux efficiently manages app data and debugging states, making it ideal for complex applications.

Q. Is React Native worth using?

Yes, React Native’s ability to build apps for multiple platforms with a single JavaScript codebase makes it highly valuable.
