React Native is an excellent tool for building native mobile apps, but certain best practices should be followed to ensure a smooth development process.

React Native is a great platform for building mobile apps, but certain best practices should be followed to create high-quality apps. This article will discuss some of the standard React Native best practices that will help you create better apps.

Key Takeaways

What is React Native?

React Native is a pure JavaScript framework that makes it easy to write real, natively rendering mobile applications for iOS and Android.

Typically based on Facebook’s JavaScript library, React Native helps you build user interfaces,but instead of targeting the browser, it targets iOS and Android platforms .

React Native Best Practices to Follow in 2023

After looking at the basics of what is React Native, it’s high time to explore the react native best practices that you must follow. Such react native style best practices help you design and build robust mobile applications for your business needs smoothly.

1. Implementing an Innovative Design System for React Native Application

   One of the most challenging factors for developing React Native application is selecting the perfect and regular styling for your business application.

   In the React Native app development, you’ll come across the terminology “Design System”, which typically manages the rules and techniques to implement the best apps.

   However, to implement the best design system for React Native apps, you need to consider the following factors: Space, Color, and Typography.

   • Analyzing the space for your application: As you’re working on a cross-platform application, it’s quite apparent that the components will have different screen sizes. So, it becomes mandatory to take care of the spacing between them to get the best possible outcome.
   • Selecting the preferred and right colour: Colour selection is the primary option you need to choose when identifying how to use them. The best alternative is to utilise Color Palettes, which make it easy to identify your colours according to your chosen naming standards and streamline your workflow.
   • Typography: One of the best practices of React Native application that we need to follow is working hard on how typefaces affect our application’s performance appearance in the results. So, keep minimized font families, weights, and sizes to get a responsive and unified design.

2. Make a Habit of Using TypeScript Programming Language

   TypeScript is nothing but an extended language of JavaScript that includes only type definitions. So, if you’re designing and building React Native applications using TypeScript, it helps reduce the dependency on PropTypes validation and lets you validate any possible errors on time.

   PropTypes validation typically occurs only during the runtime component rendering. Also, if a function component receives an incorrect prop, it may cause bugs and errors in your app.

   Unfortunately, such errors often remain undetected in the initial stage of building an app in React Native. In addition, Typescript is solely responsible for solving this particular issue while autocompleting the valid values for the components.

3. Use Platform-Centric Styles

   One of the common best practice React Native that you can implement is styling your React Native app better. And how is that possible? It’s due to an in-built API (Application Programming Interface) of React Native that helps you write platform-centric codes.

   How can you define the platform compatibility for your React Native application? The answer lies in the command “Platform.OS”. It automatically detects a specific OS like Android or iOS and applies suitable styles for that particular platform.

   Let’s explore an example to demonstrate the usage of platform-centric styles for your business application.

   Copy

   flex: 1,
   
   ...Platform.select ({
   
   ios: {
   
   fontFamily: 'Arial',
   
   },
   
   android: {
   
   fontFamily: 'Roboto',
   
   },
   
   }),
   
   },
   
   });
   
   

4. You Must Follow Strict Naming Conventions

   In react coding standards naming styles and practices are essential factors you must consider while building robust React Native applications for your business needs. The primary goal of strictly following the naming practices is to provide a smooth mobile app development experience.

   But how do you achieve such a smooth development experience? You just need to take care of the following parameters with react best practice and you’re good to go.

   • Always use small letters to provide a name to folders and sub-folders.
   • Use a pascal case to give the files’ names inside the folders.
   • You must adopt the path-based function component naming system. It means you need to name the component regarding the relative path of the folder component or to the application directly.
   • If you have files and folders with the same name, you are not required to name them again. For example, the file path components/user/register/Register.js can be efficiently written as UserRegister.js.
   • Always make a habit of giving a class component name and file name the same, as it will help you import.

5. Implementing Static Image Resources

   One of the standard best practices of React Native application is managing your static image resources the right way. In simple words, we can say that your React Native applications need to be capable of handling static image resources as there are more chances of utilizing a lot of time to work with static files.

   How would you add a static image to your React Native application? The best react native practices to include the static image in your application is that the image name required is defined statically.

   Copy

   //An incorrect way: 
   var icon = this.props.active ? 'icon-active' : 'icon-inactive';
   ;
   
   
   //The Correct Way
   var icon = this.props.active 
   ? require('./icon-active.png')
   ? require('./icon-inactive.png');
   ;
   
   

6. Creating Aliases in Your Coding Structure

   One of the common issues that many React developers face while developing mobile application is dealing with nested imports. So, the best way to eliminate that particular issue is to create aliases in your React Native application.

   For example, using ActiveButton from ‘../../Components/Buttons’. Moreover, you can use babel-plugin-module-resolver to create such aliases.

7. Always Assign a Unique Key to Each Element

   In React or React Native, assigning a unique key can solve many issues that make it harder to work with applications containing React Native components such as Lists.

   Now, let us go through a simple example of assigning a unique key to every element mentioned in the React Native application.

   Copy

   const todoItems = todos.map((todo) =>

   {todo.text}

   );

8. Dividing Components

   Before deep diving into dividing functional components sections, let’s understand what functional components are. It’s a JSX code that depicts what you want to display on your screen.

   If you’re dealing with React Native application, one of the standard best practices that you must follow is splitting the platform specific code components into two separate directories: Container component and Plain.

   Apart from this common practice, you must instruct your React Native or React Developers to utilize redux hooks and even import components. This is done to deal with styles, types, and, most importantly, reusable components.

   Moreover, it is not advisable to import JSX codes directly from RN components into your React Native application. But, the high-order components typically associated with the Redux store and its related elements must be included inside the container component.

Conclusion: Best Practices for React Native Development

You must adopt React Native best practice to develop a top-notch React Native application for your business needs.

Moreover, learning, practising, and implementing mobile applications using React is an easy process, if you strictly follow the React Native best practice.
