React Native – A Future of Hybrid Mobile Apps
React Native nowadays has become a growing technology in IT industry. Facebook, Instagram, and Airbnb all built the latest versions of their mobile apps using React Native.
1. Story Behind The React Native:
The story of React Native is quite fascinating: what started as Facebook’s internal hackathon project, in the summer of 2013, has since become one of the most popular frameworks.
The first public preview was in January of 2015 at React.js Con. In March of 2015, Facebook announced at F8 that React Native is open and available on GitHub.
After a little over a year, React Native’s growth and adoption rate doesn’t show any signs of slowing down. The statistics on Github repository are impressive: 1002 contributors committed 7,971 times in 45 branches with 124 releases, and it’s 14th most starred repository on GitHub. Plus, it’s constantly updated; React Native is following a two-week train release, where a Release Candidate branch is created every two weeks.
React Native was backed up by two tech behemoths at this year’s F8 conference: both Microsoft and Samsung committed to bring React Native to Windows and Tizen. In the near future, we can expect more Universal Windows Platform and Smart TV apps to be built with React Native.
With the support of both community and tech giants, it’s not a surprise that React Native is a trending topic and framework. For the first time in the past 12 months, search terms for React Native surpassed iOS and Android development according to Google Trends.
React native achieve a level of performance that is indistinguishable from native apps built with java or Objective – C or Swift latest version.
2. What is React Native?
- Plus, because most of the code you write can be shared between platforms, React Native makes it easy to simultaneously develop for both Android and iOs.
- Then, under the hood, the React Native “bridge” invokes the native rendering APIs in Objective-C (for iOS) or Java (for Android).
- Thus, your application will render using real mobile UI components, not webviews, and will look and feel like any other mobile application.
- Some anecdota: Facebook, Palantir, and TaskRabbit are already using it in production for user-facing applications.
3. Who’s Using React Native?
- There is a list of companies who uses react native for developing an Hybrid native app but some most popular companies are.
4. Advantages of Using React Native :
- The fact that React Native actually renders using its host platform’s standard rendering APIs enables it to stand out from most existing methods of cross-platform application development, like Cordova or Ionic.
- Performance vice this gives totally same experience as native app.
- In contrast, React Native actually translates your markup to real, native UI elements, leveraging existing means of rendering views on whatever platform you are working with.
- Additionally, React works separately from the main UI thread, so your application can maintain high performance without sacrificing capability.
- Additionally, React Native lets you take advantage of intelligent debugging tools and error reporting. If you are comfortable with Chrome or Safari’s developer tools, you will be happy to know that you can use them for mobile development, as well.
- We can create a small component and we can re-use it in another file and also in project.
- Hot Reloading is similar in concept to Instant Run on Android/IOS. Every time a source file was saved, the changes were deployed immediately on the device where the app was running, thus greatly expediting the feedback loop.
5. Drawback and Risks:
- The largest risk is probably React Native’s maturity, as the project is still relatively young.
- iOS support was released in March 2015, and Android support was released in September 2015.
- One most bad thing is react native is from Facebook but there is no specific IDE that can help developer to do easily code without worrying about there syntaxes.
6. Type Errors :
- The language does not enforce type of variables and parameters to functions, Any variable can be anything at any time
Lack of optionals:
A very large amount of bugs in Objective-C code (and in many other older programming languages) are due to programmers inadvertently calling methods on objects that are nil. Swift did away with this problem by implementing optionals, which force you to take required nil checks if you know that an object can be nil.
Lack of function signature:
You can’t trust arrays:
Poor error handling:
You can throw anything you want as an exception; a string, a Date, a function, etc. There is no mechanism for you to mark a function as potentially crashing your teammate’s code or for specifying how to process an exception.
7. Cordova vs React-Native :
How does your App access the hardware components in Cordova: –
- The key point to notice here is that the application runs in the webview, and not natively on the hardware, which makes it less performant than the native Android or native iOS applications. But then, all apps are not required to be super performant, it is a tradeoff and decision that you need to make upfront.
- Than React Native is Better than other Cross Platforms?
- React native is relatively new but an excellent option for rapid mobile applications development, and you can target both iOS and Android.
- React native is the open source framework from the house of Facebook and is used for developing native iOS and android apps.
- Apart from React framework, you need to understand JSX, JSX is the XML like syntax extension of ECMAScript.
- You also need to work with XCode, iOS simulator and command line tools for building Android version of the app.
8. React-Native vs Xamarin :
- You can build native mobile apps and it is one of the most used platform for app building With Xamarin, you can build native Android, iOS, Windows and MAC Apps in “C#” language.
- Xamarin is not the easiest to work with but gives you the performant mobile applications. You develop code in C# and Xamarin compilers compile the code into native packages of respective platforms, may it be iOS, Android or Windows Phone. For iOS, the code is directly compiled to the ARMS assembly binary, so it is purely native.
