React Native development: A complete guide for decision makers

Your competitor just launched their mobile app on both iOS and Android. Your team is still debating whether to hire iOS developers first or Android developers. By the time you ship on one platform, they've iterated three times based on real user feedback.

Native development can definitely be worth the extra time and cost. And, as we’ve witnessed many times, a cross-development platform can be a powerful way to gain competitive advantage.

React Native is a framework that's helped numerous businesses ship quality apps fast - from those in the Fortune 500 list to bootstrapped startups. This guide shares more about this development framework that we know and love here at Voyage. This is all about getting away from the hype to bring you the real story and help you make the best decision for you and your business.

What is React Native and how does it work?

React Native is an open-source mobile application framework created by Meta (formerly Facebook) in 2015. Unlike traditional mobile development that requires separate code bases for iOS and Android, React Native allows developers to write code once and deploy it across both platforms.

The framework uses JavaScript and React (a popular web development library) to create native mobile applications. This means React Native apps aren't web apps wrapped in a mobile container, they're genuine native applications that deliver performance and user experience comparable to apps built with Swift (iOS) or Kotlin (Android).

React Native also bridges JavaScript code with native mobile components. When you build a React Native app, the JavaScript code communicates with native APIs, allowing your app to access device features like the camera, GPS and sensors while maintaining native performance. To put it simply, this architecture enables React Native developers to create applications that look, feel and perform like native apps while writing significantly less platform-specific code.

Why do businesses choose React Native for app development?

It’s a cost-effective means of building a mobile app

One of the most compelling reasons why businesses choose React Native is cost efficiency. Traditional native app development requires two separate development rounds, one for iOS development and another for Android development. With React Native, developers can build and maintain applications for both platforms simultaneously. With a limited budget, this efficiency can be the difference between launching a mobile app or not.

Build time is less, meaning faster time to market

Speed matters in today's competitive landscape. React Native enables faster development as the app only needs to be built once for both mobile platforms. On top of this, code reusability and hot reloading allows developers to see changes instantly without recompiling the entire application, also speeding up dev cycles. This accelerated timeline means apps can be validated with real users sooner, and this feedback baked into the final product.

React Native offers access to a large talent pool

Finding skilled mobile developers can be challenging. React Native developers leverage JavaScript, one of the most widely-used programming languages in the world. This means your talent pool is significantly larger compared to finding specialised iOS or Android developers. In addition, web developers familiar with React can transition to React Native mobile development with a relatively short learning curve.

The framework has a strong community and corporate backing

React Native benefits from Meta's continued investment and support, ensuring the framework evolves with the latest mobile technology trends. Major companies including Microsoft, Amazon, Bloomberg and more use React Native in production, showcasing its ability to cater to large and complex applications.

The React Native community is one of the most active in mobile development, with thousands of open-source libraries, tools and resources available. This ecosystem support means React Native developers can solve problems faster and implement features more efficiently.

Ongoing maintenance is simplified

Simplified maintenance is a notable advantage of using React Native. Developers can implement bug fixes and feature updates once, and the changes automatically apply to both iOS and Android platforms. This unified approach reduces time and costs while maintaining consistent performance across devices.

When does React Native make the most sense for your mobile app development project?

Let’s be honest, React Native isn't universally the best choice for every mobile application - understanding where it excels will help you to make informed decisions. Here are what we consider to be some of the best use cases for React Native:

• Content-driven applications: Apps focused on displaying and interacting with content, such as social media platforms, news applications, eCommerce stores and booking systems. These applications benefit from code sharing without sacrificing user experience.
• MVPs and startup applications: If you're validating a business idea or building a minimum viable product, React Native allows you to test your concept across both platforms quickly and affordably. You can iterate rapidly based on user feedback without maintaining two separate code bases.
• B2B applications: Enterprise tools, customer portals and internal business applications typically don't require device-intensive features. React Native developers can build these applications efficiently while maintaining professional standards.
• Cross-platform consumer apps: Applications that need consistent experiences across iOS and Android benefit from React Native's shared code base. This ensures feature parity and reduces the complexity of maintaining platform-specific functionality.

When should you consider alternatives?

While we think React Native is brilliant and the framework can handle most application requirements, certain scenarios may warrant native development or alternative frameworks:

• Performance-critical applications: Apps requiring intensive graphics processing, complex animations, or real-time performance (like advanced gaming or AR applications) may benefit from native development's direct hardware access.
• Heavy native integration: If your application depends extensively on platform-specific features or needs deep integration with device hardware, native development might offer more straightforward implementation paths.
• Highly platform-specific design: Applications that need to deeply embrace platform-specific design languages and interactions may require more customisation in React Native than native development.

So you’ve decided to use React Native, have you considered…?

Once you’re certain React Native is the framework for you, and you’re ready to dive into your project, make sure you consider these important fundamentals.

Performance optimisation

While React Native delivers excellent performance for most applications, there are certain techniques that ensure development is optimised. This includes minimising re-renders, using performance monitoring tools, implementing efficient list rendering and occasionally writing native modules for performance-critical features.

Third-party library management

The React Native ecosystem includes thousands of community-maintained libraries. Experienced React Native developers evaluate libraries carefully, considering maintenance status, community support and compatibility with your target React Native version.

Platform-specific considerations

Despite code sharing, React Native applications should respect platform conventions. iOS and Android users have different expectations for navigation patterns, interface elements and interactions. Skilled React Native developers implement platform-appropriate experiences while maximising code reuse.

Upgrade strategy

React Native releases regular updates with improvements and new features. Your development team should establish an upgrade strategy that balances staying current with maintaining application stability. This typically means upgrading during major feature development phases rather than for every minor release.

Have you found the right mobile app development team?

Not all developer teams are built equal. Here are a few important markers of an expert development team.

React Native developers should demonstrate a deep understanding of modern JavaScript and React fundamentals, for instance hooks, state management and component lifecycles. They should also have solid mobile development knowledge, particularly in areas such as navigation, performance optimisation and responsive design across different screen sizes.

While React Native saves developers from having to delve into native development, exposure to iOS and Android development is valuable as it enables teams to troubleshoot platform-specific issues and implement custom native modules when necessary.

Proficiency with state management solutions such as Redux, MobX or the Context API is crucial for building scalable and maintainable applications. Strong API integration skills are equally important - developers should be comfortable working with RESTful APIs and GraphQL, as well as managing asynchronous operations.

Beyond technical expertise, practical experience can make a huge difference in the final outcome of your app. Developers should be experienced with the complete development lifecycle - from initial planning and design through to deployment - and understand app store submission processes and requirements. Familiarity with testing frameworks, quality assurance practices and continuous integration and deployment (CI/CD) pipelines is also a must.

The key to success with React Native

Ultimately, success isn't just about choosing the right framework, it's about partnering with skilled React Native developers who understand both the technology and your business needs. With the right team and realistic expectations, React Native can accelerate your mobile strategy while delivering high-quality applications your users will love.

As you evaluate your mobile development options, consider your specific requirements, timeline, budget and long-term maintenance needs. For many, React Native is an exciting means to building and shipping a powerful mobile app that captures the attention of users, making them want to return again and again.
