Navigating Success: A Guide to React Native Best Practices

While many developers use react native, not all know React Native's best practices. 

Often, developers need guidelines when writing code. In the initial stage, it may be unnecessary to follow specific practices. However, as your codebase expands, adhering to guidelines becomes essential.

Why is there a need to follow these practices?

They help you create an excellent platform for developing high-quality apps and ensure a smooth development process for building mobile apps.

This blog will delve into a few React native best practices you should remember while working on the same.

Let's start exploring!

What is React Native?

React Native is a JavaScript framework designed to create native apps for both Android and iOS projects. It allows for the development of React Native for both existing Android and iOS projects and from scratch.

It was released by Facebook as an open-source project in 2015. In a couple of years, it became one of the top solutions for mobile development. It has been successfully adopted by hundreds of businesses worldwide, including Uber, Facebook, and Microsoft.

Before we learn what the React Native best practices are, let deep dive into the advantages of react-native:

Cross-Platform Development

The capability to reuse code is the most significant advantage of React Native. Every brand would appreciate it because the apps can run effectively on multiple platforms. Also, it gives you the facility to speed up development time by including pre-built components from the open-source library, reducing development time.

Larger Developer Community

An open-source community means developers contribute their knowledge to react native development. This is done to ease the work of developers whenever they need help resolving their issues and improve their coding skills, facilitating smoother project development.

Cost efficiency

Another advantage of React Native is greater cost efficiency. This is because developers can use the same code to build applications for both iOS and Android apps. The cost of developing apps in React Native is much lower than apps built using languages that don't support cross-platform app development.

Fast Refresh

It allows the developers to run the app while updating it to the new versions and modifying the UI. The changes are visible immediately, and the developer doesn't need to rebuild the entire app.

The quick refresh will help you with two benefits: one is time-saving, which means programmers save time on compilation, and increased productivity, which means they don't lose any state while incorporating changes into the app.

Simple UI

Creating a user interface through React Native is simple, using a declarative programming approach. It employs component-based architecture, breaking UIs into smaller, reusable building blocks known as components. 

Fast Application

React Native is known for its ability to develop fast applications. One factor contributing to the immediate application is the framework design, optimized for efficiency by employing a separate thread to manage UI interaction and animations. This approach ensures a responsive UI even during heavy processing.

React Native Best Practices to Follow in 2024

Implementing an innovative design system for the React Native application

Developing a React Native application is difficult when selecting the perfect and regular styling for your business application. Factors such as space, color, and typography. Requires careful consideration. Let's explore them one by one:

Space - Consider components that adapt to different screen sizes, maintaining appropriate spacing for optimal outcomes.

Colour - Choose a design palette that facilitates easy identification and usage, aligning with your brand image.

Typography - Even while designing a website or working on a React Native application, we need to work hard on how the typeface will appear on our application. We will minimize font size to get responsive and unified designs through this.

Start using the TypeScript programming language

One of the React native best practices is TypeScript, an extended language of JavaScript. It helps to catch potential bugs during development through strict type checking.

Secondly, it enhances code readability and maintainability, providing a straightforward interface for better documentation and organization.

• Platform-centric styles

One beneficial tool is using React native built-in API to write platform-centric code, utilizing platform-specific style components or conditional rendering. This approach ensures UI elements look native on each platform, enabling responsive design across various devices and orientations for a consistent and optimal user experience.

Following Strict Naming Conventions

In React Native, naming styles and practices are essential factors you must consider while building robust Reactive native applications for your business needs. We need to adhere to consistent naming conventions that improve code readability and maintainability:

It reduces confusion and errors by establishing predictable naming patterns for a better understanding of functionalities and minimizing mistakes caused by misunderstandings among developers.

Implementing Static Image Resources

In React Native, utilizing static images such as PNG, JPEG, or SVG files instead of dynamically loaded images can help you enhance app performance. These static images are bundled with the app during the build process, reducing the need for runtime fetching and improving overall speed.

Assigning a Unique Key to Each Element

During React Native development, assigning a unique key to each rendered element enables React to identify and update components during re-rendering efficiently. This will help you improve performance and prevent unnecessary re-renders. 

Dividing Components

Dividing components into smaller, reusable, or reusable pieces is a best practice with several benefits. The dividing components will benefit you in the following ways:

Easier maintenance 

Smaller, focused components are easier to maintain, with each element having a single responsibility, such as debugging, testing, and ensuring that changes become more straightforward. This practice aligns with the principles of separation of concerns, where each component will focus on the specific tasks.


Breaking down the UI into components makes it easier for you to scale your application. As and when your app grows, adding, modifying, or replacing components becomes more manageable without affecting the entire codebase. This flexibility helps to manage complexity and accommodates future changes.

Reusability and modularity

Dividing your UI into smaller components allows the creation of modular building blocks that can be reused throughout the application. Each component handles specific functionality or represents a distinct UI part, simplifying code management and prompting reusability.


To sum up, we hope you got clarity on React Native best practices and how effectively implementing them can facilitate the growth of your iOS and Android apps. We also highlighted the benefits of adhering to these practices, emphasizing the crucial role of cross-platform development in ensuring successful launches for your business applications.
