7 Mistakes to Avoid When Developing React Native Apps

React Native has quickly become one of the most popular frameworks for developing mobile applications. However, with this increased popularity come mistakes that are often made by novice React Native developers. From not following best practices to neglecting testing, these top 7 React Native development mistakes to avoid will help you stay on track while developing your next mobile app.

Let’s begin!

Why do app developers choose React Native?

• React Native Uses JavaScript

JavaScript is one of the most promising languages​​ that help developers to build interactive applications for Android, Android TV, iOS, tvOS,macOS, Windows, Web, and UWP. In fact, React Native relies heavily on JavaScript, which saves a lot of time and makes development easier.

• Being Able To Build Native Apps

Despite working with JavaScript, developers do not render React Native components using Web views. Most web app developers prefer to go with React Native because it can render true native elements, allowing them to use platform-specific components more freely.

• Simple Installation Process

The most beautiful thing about React Native is that it can be installed without any hassle. All you need to use is Node Package Manager to install React Native Framework. Even if you don't know much about JS, React Native can do it for you as it can download binaries from the source code.

• Higher Productivity

Developing mobile apps faster lies in app developer productivity. Moreover, it has made developers’ life easier as it provides freedom to use any text editor or IDE.

• Strong Community Support

React Native has grown in popularity since its launch in 2015. Developers and businesses or startups from every corner of the world have chosen to go with React Native for its many benefits.

As a result, this high demand has led to the creation of a strong community, that works together to align the pros and cons of React Native on a daily basis.

• React Native Is Cross-Platform

By using React Native, mobile app developers with basic knowledge can increase their skills to smart TVs, Windows devices, smartwatches, and even VR headsets.

Aside from the advantages of React Native app development, there are certain inherent challenges mobile app developers may face while developing mobile apps. To avoid unnecessary risks, contact a mobile app development company having excellent knowledge in React Native app development with the most up-to-date features.

Top 8 React Native Development Mistakes to Avoid

1.  Wrong Estimate

Layouts for iOS and Android Versions- These two operating systems will contain some reusable components, but can also contain many different layouts. In fact, on iOS and Android, the structure of an app page can be differentiated completely.

Form- You should estimate the validation layout. When creating apps in React Native, you have to write more code than when creating Hybrid apps on Cordova.

Web Application Creation-You should try out all of the backend's different endpoints. Also, since the logic must be handled in the application, everything must be coded appropriately. As a result, you should have a thorough understanding of the database's structure, how the entities are connected.

2. Redux planning

As a developer, when you get a creative project, you should focus more on planning the layout of the application and less time on the data processing.

Redux helps store data correctly and helps manage and correct application states. When properly planned, Redux can be a powerful tool for managing application data.

Another problem that you need to keep in mind is that Redux is not the right choice for small projects. Therefore, you should use Redux for large scale applications and avoid using it when developing React Native for startups.

3. Do not read external Module's code

External Modules will make the process easier and faster, provide the necessary documents and save time effectively. However, these modules may be damaged or not working as expected. This is why developers should read the code and consider this step as one of the important methods when developing React Native apps.

4. Changing the state inside the Render. function

Normally, datastore (Datastore) and view (View) will be connected to each other. The datastore is where all the data in the component and views are displayed on a state basis. Then the datastore uses the new State and displays it on the screen.

To accomplish this process, React's setState() function retrieves a state and compares it with the previous state. Next, a new state will be added after merging with the previous state and sent to the data store.

This cycle is available during the “lifecycle” of a component when you develop your app in React Native. If the state changes directly, this "lifecycle" will be affected and corrupt all previous states. This leads to abnormal application behavior or even crashes. In addition, you may also lose the ability to track states on the component and lead to having to write custom code in place of React.

5. "console.log" statement

Console log statements are extremely handy, capable of providing debugging help during App development. But what happens when you leave Log statements in the application?

This can become a serious problem if you include Render and Logic methods inside, especially those that are asynchronous with them which can lead to bottlenecks in the JavaScript thread. This error will make the application work slower.

6. Unit testing

Often developers skip writing unit tests, mainly because they are time-consuming. But what they don't realize is that a little extra time at this stage can save them a lot of time and resources after launching the App.

7. Optimized Images

Often mobile app developers or designers overlook the importance of optimizing the images. However, image optimization is very important and special attention must be paid to it. Because it has the potential to affect the app's functionality.

Conclusion

Making mistakes as a developer is a common occurrence. However, with the best practice, you may easily avoid some of the errors. React Native, on the other hand, has a bright future in the developer community due to its simplicity of cross-platform application development. As a result, investing time and money in React Native app development is worthwhile. If you want to build a cross-platform mobile app for your business then you can hire react native app developer.
