React Native has quickly become one of the most popular frameworks for developers since it’s original release five years ago. The framework started as an internal hackathon project for Facebook in 2013 and was released to the open source world two years later. React Native enables developers to create cross-platform apps for iOS, Android, and Windows Mobile. It’s easy to learn and has a loyal, active community supporting it. We’ve compiled an ultimate guide to React Native and answered some common questions such as:
We’ve also provided some great React Native examples of some of the top companies that have adopted React Native for their mobile apps. Keep reading to learn more about one of the most popular mobile app frameworks.
ReactJS has been around for almost a decade. It gained incredible popularity when leading brands like Instagram, Dropbox, and Netflix implemented it in 2015. The same year, React Native was released. However, with incredibly similar names, it’s left some developers wondering what the differences are between ReactJS and React Native.
Simply put, ReactJS is used to create web pages to be viewed in a web browser. Alternatively, React Native helps developers create mobile apps for Android, iOS, and Windows Mobile. You can compile these apps and put them in their respective app stores for users to download. While ReactJS uses web components as building blocks, React Native uses native components, hence the name.
So, how does React Native work? There are four quintessential threads in every app built with React Native:
The UI thread, commonly referred to as the main thread, renders and displays native iOS and Android UI elements.
The native modules thread provides your app with access to platform API when needed.
Lastly, the render thread, which only Android L (5.0) uses, is used to generate OpenGL commands.
So, how do these four threads work together? Developers use the bridge to help interactions between UI and JS threads. Bridge works in one of the following ways:
Angular and React both provide frameworks for developers to create mobile apps. Both have strong, loyal followings. It’s subjective which platform is better, but many strongly prefer React Native. If you’re wondering ‘why is React better than Angular,’ we’ve broken down a few basic similarities and differences.
Angular was created as an MVC Framework. Depending on personal opinion and your project, this could be a benefit or a drawback. The benefit of working with Angular is that it comes standard with a considerable amount of functionality. This means after downloading, you’ll be able to get to building your project much quicker. You won’t have to consider routing libraries or utilities for unit-testing components – it all comes standard. While this does mean you can get to coding faster, it also provides less flexibility. If you have strong opinions of libraries and other add ons, and they differ from what Angular forces you to use, Angular may not be for you.
Alternatively, React doesn’t come pre-loaded with many of these add ons. This means you’ll have a bit more set-up to do before jumping into your project. However, it also means you’ll be able to customize your MVC to your liking before getting started. The learning curve may be steeper, but it’ll produce an entire MVC framework that is personalized to your work style.
In addition to this, one of the most talked-about features of React is its use of Virtual DOM. We won’t go in-depth here, but mostly, Virtual DOM renders updates incredibly fast compared to the Regular DOM used by Angular. In addition to making React lighting-fast, Virtual DOM also improves UX.
Since it’s initial release in 2015, React Native has come a long way. From hot, new startups to Fortune 500 Companies, a wide range of industries and companies are building apps on React Native. We’ve compiled a list of a few great React Native examples below.
Since ReactJS and React Native were initially created by Facebook developer Jordan Walke, it’s not surprising that Facebook has been one of the most significant supporters of React. While all the Facebook apps use React Native, the Facebook Ads Manager app was the first app built by Facebook exclusively on React Native. In fact, it was the first cross-platform app ever created with React Native. The Ad Manager app allows users to quickly and simply manage their Facebook ads with the intuitive user experience and an uncluttered interface. Since the ad manager, on both desktop and mobile, deals with an intricate amount of data, it was a natural fit for React Native.
Since Facebook owns Instagram, it doesn’t surprise that the mobile social media app is also using React Native. Two years after Facebook acquired the photo-sharing platform, the Instagram dev team began integrating React Native with the existing app to ship features faster to both iOS and Android versions. This was actually one of the first projects where developers started implementing React Native into an existing app.
Currently, at the top of the Fortune 500 list, the retail giant Walmart started shifting its iOS and Android apps over React Native in 2018. The development team utilized code sharing between iOS and Android apps. In fact, 95% of the codebase is shared between the two operating systems. This helped the team implement changes across both apps more efficiently while reducing the time-to-market.
While the main ridesharing app, Uber, isn’t powered with React Native, Uber Engineering decided to use React Native to power its newer app, UberEATS. Similar to the ridesharing app, UberEATS was an innovation in food delivery. It also allows Uber drivers to pick up food deliveries, facilitating communication between restaurants, drivers, and hungry people.
Wix is a CMS and online website building tool that allows people and businesses to create websites with no knowledge of coding. The Wix app allows its more than 154 million users to create and manage their sites. Producing an app at this scale on React Native was estimated to be completed 3 times quicker than usual.
Gyroscope is a health and fitness app for iOS and Android that helps users achieve their wellness goals. From losing weight to increasing productivity, Gyroscope tracks your progress to help you achieve your goals. It collects data on your health and provides recommendations to help you live a healthy life.
With all the data collected and produced, this complex app was the perfect fit for React Native. The app seamlessly integrates with different software and hardware, like FitBand. Gyroscope’s dev team claims using React Native helped significantly speed up their development time and helped them produce an easy to use app helping users live their healthiest, best lives.
