Best Practices for React Native Development

With React Native, developers can approach app development in two ways: conventional and Expokit-based. To create apps more quickly and easily, app developers must be familiar with a few best practices, which we will explore. The react native best practices that developers should follow while creating applications using React Native are discussed.

React Native was founded in 2011. It was designed to facilitate the development of user interface templates via the usage of JS threads. RN, which was introduced in 2015, is a logical extension of React. It is a cross-platform development environment that enables the creation of native apps utilizing JavaScript and Native components written using React. Nearly a tenth of all applications accessible on the app store are projected to be produced with RN.

React Native Best Practices

Without regular style, achieving the most satisfactory potential outcomes is difficult. A Design System compromises a collection of rules and concepts that establish an application’s visual and tactile characteristics. You should keep four points in mind while you work with your design system.

Space: When working with a cross-platform application, the screen sizes of the various components on a screen may vary but ensure that the spacing between them is constant for a cohesive design.

Colour: Choosing the right colours is critical, but so is how you utilize them. A smart alternative is to utilize Color Palettes, which allow you to identify your colours according to your chosen naming standards, so streamline your workflow.

Typography: We often overlook how typefaces affect how our application appears in the results. To get a pleasing, unified design, it’s recommended to keep to a small number of font families, weights, and sizes.

The necessity for flexible design is evident in Web Applications, where screen sizes vary from a tiny mobile device to a widescreen desktop computer. However, with React Native, when the target device type is limited to mobile devices, it may be faulty with the same device size, but the range in screen dimensions is already large enough that finding a one-size-fits-all solution for designing the application is complex.

To use responsive design effectively, you may establish specific breakpoints by classifying various screen devices.

TypeScript and React are ideal pairing, even more so when working in Visual Studio Code. Instead of relying on React’s PropTyes validation, which occurs only when the component is displayed at runtime, TypeScript lets you verify any faults in your project. Additionally, you may configure property types to accept only values found in the theme, which will cause your editor to autocomplete the acceptable values for you.

Without the Platform API, you would end up with a plethora of distinct styles for various platforms ( Android & iOS); to manage these styles, you may utilize the Platform module for Stylesheets. You may use Platform OS to identify the operating system automatically and then apply the appropriate styles.

React Native combines pictures and other media assets so that your iOS and Android applications can use them. To include a static picture in your application, you must ensure that the image’s name in need is known statically.

Whatever your needs are, optimizing React Native graphics should be your first concern. Therefore, resize the photos locally and upload them to cloud storage such as s3 through the server, obtain the “cdn” address, and return them using an API. These procedures enable you to load photos more quickly.

Though React Native has an API that allows you to develop code that runs on both platforms, you will always write platform-specific code like stylesheets and callbacks. Moreover, to improve code organization, the Platform module for stylesheets is the optimal solution to handle styles.

Working with the React and React Native frameworks necessitates the development of a dedicated testing environment capable of tracking down and resolving bugs promptly.

Jest is a JavaScript library that is freely available for testing code. There are several ways to test React Native applications. Snapshot testing and Redux testing are two of the most popular types.

With snapshot testing, you may get a snapshot of the string that contains the displayed element’s information.

Redux testing is one of the best practices a developer may opt for since it enables tracking of changes made to the state of applications. You may do a predictable check for changes.


React Native enables you to create the most sophisticated user interfaces in a matter of minutes. Moreover, works flawlessly across iOS and Android. More importantly, react native is unquestionably the new hope for development.

With an ever-growing React native community, the technology is unlikely to become obsolete anytime soon-especially given the community’s enthusiasm for the technology’s utility and low weight. React Native is the newest buzzword.
