Why is it worth using React Native in 2022?
Cross-platform development is not only a passing trend – it has become something obligatory in modern app development. React Native, as a cross-platform tool, allows for building mobile applications for IOS and Android simultaneously. Hence, the basic knowledge of this framework is essential for developers. Let’s discover the main benefits of using React Native for your mobile app project:
Developing cross-platform applications fosters code reusability. That’s the big advantage for developers who no longer need to generate codes for each platform separately.
Faster app development
ReactNative requires only one codebase to manage both iOS and Android. Since everything is in one place, app development becomes much faster.
Native app development requires hiring different specialists – one for iOS and one for Android. Needless to say, the ability to reuse code and faster development can lead to lowering overall project costs.

Top Best Practises for React Native Developers in 2022
React Native is a technology with great potential and turns out really useful when performing your daily tasks in the project. We’ve gathered the top 8 tips to help you code like a pro!
1. Remove logs on production
Turning off all logs from your release builds is crucial here. You can do this either manually or with a script. Why is it so important? Too many console.log statements will slow down an application.
2. Organize your components
App development is not only about writing your code – it requires good organization. Ordering components is the key to success with React Native. Classifying your components into smart and functional categories is a really good way to maintain the logic behind the whole project. Smart containers transfer data from APIs, and functional ones display data to users. Such classification fosters further reuse of components.
3. Keep up with a consistent style
Remember to name all the components consistently. For instance, when you name a given style object container, stick to this naming within the whole project. Otherwise, you can end up with a long list of components, each of them performing multiple tasks.
4. Monitor how complex your code is
Growing (and active) react-native community offers many tips and tools that will help you improve the performance of your apps. It’s good to take advantage of it and use free tools to check the level of complexity of your code. Thanks to extensions like code metrics, you can track and measure your code’s complexity effortlessly.
5. Diminish your application’s size
Many factors impact the app’s size, so you should remember to reduce its size. In order to do this, you need to optimize the resources and prepare various sizes matched to different devices. Using free online tools, such as ProGuard, will help you shrink your code.

6. Segregate files
You should keep all files related to a given component in one folder. Creating folders and subfolders for the components will help you keep things organized. It’s really important while working on the React Native project (and not only), for instance, when other developers need to find some part of your code to modify it.
7. Transform your code at ease
Transforming code from one format to another can cause some problems, e.g. there’s a risk of losing data. You can prevent missing some information by using online tools and applications to update and reformat data when transforming your code, such as transform.tools.
8. Use Flexbox
Using Flexbox is always a good practice. It is a CSS tool that enables you to build layouts to fit multiple screen sizes. Without flexbox, your code won’t provide expected reusability.
