React Native: The Basics

Meet React Native, the brainchild of Facebook back in 2015. It's been making waves ever since as an open-source framework for crafting top-notch mobile apps for iOS and Android.


So, what's the big deal with React Native? Well, for starters, it's all about flexibility. With React Native, developers can harness the power of JavaScript and the React library to build native apps with ease. And let's not forget about those handy native components, seamless platform-specific code, and a community that's second to none. It's like having a superhero team at your fingertips!
But what really sets React Native apart? It's the plug-ins, baby! With a plethora of program modules at your disposal, there's no limit to what you can achieve. And developers? They're eating it up like candy on Halloween night!

React Native app development  
React Native isn't just a framework—it's a community. With a wide network of support and a robust library and ecosystem, it's no wonder it's a favorite among developers. Plus, third-party UI libraries packed with ready-made components can be a real time-saver.
But wait, there's more! React Native projects boast lightning-fast deployment of new features across supported platforms, thanks to hot reload. No more waiting around—see your changes in real-time and keep the momentum going. With React Native, it's all about speed, efficiency, and accessibility. Whether you're tweaking code in your favorite IDE or putting it through its paces in a text editor, you've got the tools you need to build, test, and deploy with ease.

React Native apps performance overview  
React Native is stepping up its game with a fresh approach to communication between native components and JavaScript code. In the past, this communication relied on a bridge for message exchange. The old bridge method involved a process called "serialization," converting data between JavaScript and native code. But here's the catch: this process could slow things down, especially in complex apps.

JavaScript Interface (JSI). With this new bridge communication method, JavaScript and native code can talk directly. No more serialization, no more message exchange, just smooth, high-performance communication. It's like upgrading from a bike to a sports car.

Bridge communication method in React Native  
JSI isn't just a fancy acronym—it's a game-changer for React Native developers. Built on the robust JavaScriptCore framework, it's like turbocharging your app's performance.Why? Because JavaScriptCore is tailor-made for running JavaScript on mobile devices, meaning faster performance across the board. 


And here's the kicker: JSI brings familiar debugging and optimization tools to the table, straight from the world of web development. Think Chrome DevTools, but for your mobile app. But that's not all. With JSI, developers can tap into JavaScript's garbage collection, keeping memory leaks at bay and supercharging app performance. It's like having a built-in cleanup crew for your code.
React Native's performance gets a turbo boost with the introduction of turbo modules! 

Rolled out in React Native 0.63, turbo modules are designed to supercharge the JSI. So, what's the deal with turbo modules? They introduce a new binary format for modules called TMD (TurboModule Definition), which kicks things up a notch in terms of efficiency. This means faster app startup times and smoother overall performance, all by cutting down on the amount of JavaScript that needs to be processed at runtime.

Take the popular React Native library, for example. Thanks to turbo modules, it's able to churn out buttery-smooth animations at a blazing 120 frames per second with react-native-reanimated. It's like giving your app's performance a shot of espresso—fast, powerful, and ready to tackle whatever comes its way.

React Native has caught the eye of some heavy hitters in the tech world, with top international brands jumping on board the React Native train. Check out this star-studded lineup:  
Meta: You might know them better as the brains behind Facebook and Instagram.

And the list goes on! These are just a few of the big names that have harnessed the power of React Native to deliver top-notch experiences to their users. So if you're looking to join the ranks of these industry giants, React Native might just be the ticket to success.

The main differences between Flutter and React Native  
To make the best choice for your project, it's crucial to understand the key differences between these two frameworks. From programming languages to architecture, performance, and beyond, we're diving deep to give you the lowdown. So buckle up—we're about to explore what sets Flutter and React Native apart and help you navigate the tricky waters of mobile app development.

Development speed and maintenance of the mobile apps  
When it comes to development speed and maintenance, React Native's use of native UI components can be a double-edged sword. While it offers seamless integration with the latest OS updates, there's a catch: these updates can sometimes break your app's interface. This means you may need to roll up your sleeves for some extra maintenance down the line.
But fear not—React Native automatically adopts any native updates, like changes in navigation gestures, keeping your app up to date without lifting a finger. Flutter, on the other hand, requires manual implementation of these updates, adding a bit more legwork to the process. So while React Native offers automatic integration, Flutter puts the power in your hands to fine-tune your app's performance and interface.

Flutter as a better fit for your MVP  
When it comes to building your Minimum Viable Product (MVP), Flutter takes the crown for speed and efficiency. With its extensive library of pre-built components, Flutter slashes development time, allowing you to go from concept to market in record time—sometimes in just a few weeks!

Here's the kicker: Flutter's components are designed to work seamlessly across platforms and operating systems, eliminating the need for platform-specific code. This not only saves developers valuable time but also cuts down on development costs—a win-win for any business looking to launch quickly without breaking the bank. Plus, Flutter was tailor-made for rapid UI development based on Material Design principles. So if speed and simplicity are your top priorities, Flutter is the MVP's best friend.

Behind the React Native slowing down aspects  
React Native's reliance on third-party libraries for widgets can be a speed bump in the development process, especially if you're in need of specific components. Unlike Flutter, which comes fully loaded with its own widget library, React Native requires you to hunt down and integrate third-party solutions, potentially slowing things down.

But here's where React Native shines: it's a powerhouse for crafting customized user interfaces. So if your project demands a lot of bespoke solutions, React Native might be the way to go.
When it comes to code reusability, both Flutter and React Native have got your back. However, Flutter edges ahead with its ability to easily overwrite specific parts of the code, saving developers precious time and effort. After all, in the world of app development, time is money—and Flutter knows how to make every second count.

Cross-platform apps performance in React Native vs Flutter  
When it comes to performance in cross-platform app development, React Native and Flutter take different routes. React Native relies on a bridge between JavaScript and native modules, while Flutter boasts most components as part of its framework, making for a smoother process.


But here's the kicker: Flutter tends to come out on top in the speed department. Why? Because all Flutter processes are fully native, ensuring lightning-fast performance. On the flip side, React Native's reliance on both JavaScript and native solutions can lead to inefficiencies, making it less than 100% native despite its name.
Take gestures, for example. React Native handles them through both JavaScript and native solutions, creating a bridge between the two that can slow things down. Flutter, on the other hand, keeps it all on the native side, resulting in snappier performance.
So if speed is your top priority, Flutter's the way to go. With its fully native processes, it's the go-to choice for developers looking to create super-swift cross-platform apps that leave the competition in the dust.

React Native vs Flutter app size comparison  
When it comes to app size, Flutter and React Native have their own stories to tell. Generally, Flutter apps tend to be on the larger side compared to React Native. The culprit? Flutter's C/C++ engine adds some extra bulk to the package.
But here's the twist: bigger doesn't always mean slower. In fact, Flutter's beefier apps often translate to faster performance in the long run. All those extra features may take up space, but they also contribute to a smoother user experience.
React Native, on the other hand, is playing catch-up in the size department. With the introduction of dedicated engines like Hermes, it's striving to keep app sizes in check without sacrificing performance.
So whether you're Team Flutter or Team React Native, rest assured that both frameworks are working hard to strike the perfect balance between size and speed. After all, in the world of mobile app development, every byte counts!
