React Native lets you build cross-platform mobile apps using JavaScript, meaning you can reach an enormous audience of Android and iOS users with the same codebase. Best of all, it’s incredibly popular—Facebook uses it for both Instagram and WhatsApp. Learn how to use React Native to build your own apps from scratch, from choosing the right stack to bundling an app ready for distribution. This guide will teach you everything you need to know about React Native development so you can launch your own project or join an existing team. hire Dedicated React Native Developer for your next Project.


How Does it Work?

First, it’s worth understanding that React Native development is only one part of what you need in order to create a finished app. The other part is native Android or iOS development, which creates specific code for each platform (such as when using Instagram’s APIs). So, before you can even begin coding in React Native, there are two important elements to set up. First, install node.js on your computer and run npm install -g react-native-cli . Then bootstrap with react-native init ProjectName where ProjectName is replaced by whatever name you want for your app.


What are the pros and cons?

Every tech solution has its own quirks and, while they can be headaches at times, they’re also what make it unique. If you plan on using React Native, keep in mind that it’s still a young platform (meaning there are still kinks in its infrastructure), and that one of your greatest challenges will be mastering cross-platform development. It isn’t always easy to deal with every operating system or device. However, as time goes on, functionality will improve—and so will your ability to make use of it. It takes a certain kind of person to push through these challenges and embrace all that is new about them; if you want an exciting career developing for cutting-edge technology platforms like React Native, you should definitely consider giving it a shot!


Why choose React Native over Flutter or Xamarin?

At first glance, it might seem like React Native isn’t worth your time. After all, you could use other cross-platform development tools, like Xamarin or Flutter. But if you want to build native apps for Android and iOS, you’ll find that using a JavaScript framework can streamline your process and reduce costs because you don’t have to hire two different teams with two different stacks. Plus, you can reuse code more easily between platforms without sacrificing functionality (or performance). At its core, that’s what React Native is all about.


How do I start?

If you’re planning on developing a mobile app for your company, there are tons of factors to consider. Here are a few questions that you might not have thought about yet. What will your development team look like? What do you need from an outsourced firm or partner? Do you need to hire employees with certain qualifications or will freelancers be enough? Should you outsource for full-scale mobile app development or start with lower-cost services, such as design and prototyping? To start thinking through these questions, pick up a copy of The Ultimate Guide to React Native Development . This book is great for learning how and why businesses choose to develop apps and what they should know before they get started.


How do I migrate from Android/iOS native development?

A question that often comes up is how does one go about migrating from native Android or iOS development over to a cross-platform solution like React Native. There are several approaches, but there’s only one true way: Write apps with native technologies for both platforms and then bring them into your app using something like react-native-wrapper. The benefit of using react-native-wrapper is that it gives you all of your source code in JavaScript, which can be easily used from within React Native. This also makes it easy for anyone who knows JavaScript (and many do) to contribute code back to your project.


Do I need special tools to code with RN?

Definitely. So far, there are more than 20k packages available on npm and 10k developers registered on Stack Overflow. A handful of businesses have already announced their commitment to using RN in production (e.g., Facebook, Airbnb, Bloomberg). The developer community behind React Native is vibrant and active. If you’re planning to build something ambitious with RN, don’t hesitate to ask for help on Stack Overflow or open an issue ticket in one of many libraries’ repositories. It’s likely someone has already asked your question!


Is there a community behind RN?

If you’ve never used React Native before, there’s probably a great community of developers willing to help you learn. Try searching Stack Overflow and see if anyone’s posted a solution. If they have, try it out! Most questions can be answered with Google and Stack Overflow. Remember that most developers love helping others so don’t be shy about asking for guidance.


Where can I find tutorials about RN development?

Want to learn more about React Native? It’s still a fairly new technology, but there are tons of great resources on how to get started. From MDN’s Getting Started guide and RN Overview page, where you can find links to both native and JavaScript-based tutorials, videos, code repositories and API references. The official project documentation is another great place for in-depth guides that cover every aspect of getting your RN app up and running. There are also some excellent developer-centric resources at Stack Overflow, as well as online tutorials from CodeSchool and Udemy. And if you want an overview of all available components for developers, we recommend checking out AwesomeReactNative by awesome-reactor repo on GitHub.
