React Native vs Ionic: Comparing Cross-Platform Solutions

Updated: May 4, 2023

Development for iOS and Android using Swift, and Java has long since been the sole concept of mobile development. We live in an era where hybrid, cross-platform, and progressive web apps are becoming more popular. Cross-platform app development used to be dominated by hybrid frameworks, such as PhoneGap and Ionic. Then there’s React Native. React Native was introduced to the market to simplify the creation of Native apps. The most crucial question in this React Native vs Ionic battle is which framework to use for developing a mobile application, and when.

To fully understand the differences between React Native and Ionic, let’s brush up on these key terms: Hybrid and Native.

Hybrid Apps vs Native Apps

Let’s take a look at some of the differences between “hybrid” mobile apps, and native mobile apps.

Native Applications

As the name suggests, Native apps are created in languages that are native to the platform for which they run. The distinctive feature of Native apps is that they are explicitly developed for specific devices. For example, Android applications are written in Java, while iPhone applications are written in Objective-C or Swift.

Regarding user experience, native apps are the fastest and most reliable. They can access all of a single platform’s features without restrictions.

React Native was developed by Facebook using JavaScript, the most used language by developers. The goal of React Native was to address the problem of poor hybrid performance and inefficiencies in creating native apps.

For a complete overview of React Native vs. Swift.

Native applications have the following characteristics:

Hybrid Applications

With hybrid applications, web technologies like HTML, CSS, and JavaScript are used to code the application, which is then compiled into a native application. The Ionic framework comes pre-configured with this feature.

No matter the operating system, a hybrid application works just like a web application and is installed on the device in the same manner as a native app. Through technologies like PhoneGap, hybrid apps can integrate with native phone/platform functions like GPS, accelerometer, camera, etc.

Hybrid applications have the following characteristics:

React Native

Cross-platform framework React Native lets you create iOS and Android apps using the same codebase. The application is written in JavaScript and uses React. Facebook open-sourced this framework in 2015 and it has gained a lot of traction ever since. The React Native framework allows you to build native mobile apps for both the iOS and Android platforms.

Ionic

By combining hybrid and native technologies, the Ionic framework enables you to create high-quality, cross-platform mobile apps. The JavaScript, HTML, and CSS technologies used in the framework enable you to create quality, cross-platform apps. You can create a single code base once and deploy it across iOS, Android, Web, and desktop platforms. All platforms use the same code base.

React Native vs Ionic: Similarities

Although Ionic and React Native have some differences, they also share some similarities. Ionic provides HTML, CSS, and JavaScript tools for coding native mobile applications. With React Native, you can develop native mobile apps in JavaScript using the popular JavaScript framework, React.

There is no need to have any programming experience in iOS or Android to begin using Ionic or React Native. In general, React Native and Ionic accomplish the same task. Nevertheless, their approaches are quite different.

Ionic vs React Native: Comparative Analysis

Technology Stack Structure

The simplest way to summarize the differences between a React Native and an Ionic application is “nearly native” vs. “web-first.”

React Native is often called “nearly native.” JavaScript and React are used to build the apps, but the underlying widgets are native to iOS or Android. Native components can communicate with JavaScript components via a bridge, which involves one-to-one communication.

As a result, React Native cannot be regarded as a native app because a JavaScript bridge links native components to JavaScript and React. With React Native, you control the platform’s UI modules directly. All the UI components in React Native apps, written in JSX instead of HTML, are native to the platform. As a result, they offer native functionality and produce native-quality mobile apps.

The Ionic framework takes HTML, CSS, and JavaScript code and renders it on a WebView (a native web browser component) to build mobile apps. Cordova or Capacitor is the technology used to connect the WebView to the Ionic codebase at runtime. Essentially, an Ionic app is a mobile website ported to a mobile app.

A second architectural difference between Ionic and React Native is that Ionic is non-framework specific. The underlying technology can be any web framework you prefer, like React, Vue, Angular, or even vanilla JavaScript. Unlike React Native, which is only built in JavaScript using the popular framework React.

Who wins? It depends. Your project’s restrictions and app requirements determine the winner in this category. For building a mobile app that looks and feels like a native app, React Native is a better choice. If you want to develop a mobile app with a web framework, or if you want the app to look and feel like your website, then Ionic may be the right choice for you.

Compatibility

Platforms supported by React Native development include iOS and Android. With the same codebase, you can build apps for both platforms, leveraging native UI components, and accessing native APIs. React Native shares enough similarities with React that some of that code can be reused to build a web application using React, but if you truly need a solid web framework, the practical value is limited.

The Ionic framework, however, is truly a cross-platform solution. It works with iOS, Android, desktop apps, and the web. One codebase can be compiled for all of these platforms with a few minor modifications. For mission-critical enterprise app development with a truly cross-platform approach (including desktop and web apps), Ionic may be the better choice.

Due to its ability to support desktop apps, and web apps, Ionic wins in this category.

Learning Curve

Both frameworks share JavaScript in their core SDKs. However, they are not the same. With React Native’s basic flex layout, obtaining a component’s style is a piece of cake. All you need is a basic understanding of CSS to begin. You might also need to learn Axios, Redux, Flexbox, and ES6 as prerequisites. While react native’s documentation is top-notch, React Native does not offer its own courses or online education portal.

Now with Ionic, Cordova installation is easier through NPM commands. You can access all Angular.js extensions and services with the element ngcordova. Moreover, Ionic has its own Ionic Academy online school, which offers different leveled courses that make learning and building much more manageable.

Ionic wins this round. The learning process is much simpler and easier. You can pick the framework you feel most comfortable with in Ionic. JavaScript, Angular, React, or even React could be used. React Native requires you to code in React, and the tech stack is not flexible. Non-React developers will have a more challenging time learning React Native.

Performance

In terms of performance, React Native beats Ionic. Frameworks using WebView rather than native components simply cannot compete in terms of performance. Because native built-in components perform better than any other type of implementation, a native app or React Native app will always be the best-performing choice. Despite not being fully native, React Native utilizes native components, which makes it faster than Ionic.

A benchmark statistic, FPS (Frames Per Second), measures performance. In general, the higher the frame rate, the more fluid and seamless the app will feel. React Native apps can sometimes reach 60 FPS without any optimization, which is a strong baseline. Ionic apps, on the other hand, often require a lot of optimizations to reach 60 FPS.

Developer Experience

If you are a web developer with little to no experience with mobile app development, Ionic will be less intimidating. It uses HTML5, CSS3, and JavaScript, just as web apps do, and offers an experience very close to web development so that you will feel comfortable writing code for it.

On the other hand, React Native will be more familiar and intuitive to mobile developers because it uses the same paradigms, they are already familiar with – the JavaScript framework.

The good news is that both Ionic and React Native provides ample documentation and the resources you need to make your app successful. Both frameworks will allow you to build an app from start to finish without needing any outside help.

Popularity And Community

Multiple resources were checked to determine which platform was the most popular. There is no doubt that the popularity of React Native has surpassed that of Ionic. However, it is important to mention that both solutions have a large community around them, with millions of customers using mobile applications and big companies adopting them.
