When it comes to creating apps with JavaScript, there are multiple approaches, and none is more popular than React Native. Some of the biggest apps on both the App Store & Play Store rely on React Native, Ionic is quite popular as well, and NativeScript is behind the two. We also use Meta's framework for creating cross-platform native apps. Curious why?
React Native
React Native is currently the most popular JavaScript framework for creating mobile apps. Neither Ionic nor NativeScript can match its popularity. Its popularity comes from the fact that it was tied to React from the start, while both Ionic and NativeScript were Angular-first (the bet did not pay off for the two).
The framework allows developers to build mobile apps using JavaScript & TypeScript and React's JSX syntax, so you can build rich user interfaces that feel native. You may even reuse the same libraries you are used to from web React, such as Formik, Redux, react-query or even tailwind (provided you install an additional plugin for handling utility classes).
When to Use It
In our view, if you're choosing between those three, you can't go wrong with React Native. It's flexible, the community support is great, and there are a ton of libraries and resources available. If the bare workflow does not suit you, you have Expo at your disposal - a great project that extends Meta's framework and adds many indispensable goodies.
What's becoming more important is that the number of React Native projects is huge, which means tools such as GitHub Copilot, Cursor, and others have more repositories to scrape, so suggestions for your code should be better.
Ionic
Ionic allows the creation of hybrid applications using web technologies like HTML, CSS, and JavaScript. The framework wraps the web application in a native container using Capacitor, thanks to which you may access native APIs from the comfort of the DOM. Because of that, however, apps will be much slower.
Of the 3 frameworks, Ionic will be the easiest to switch to for a web developer, because React Native and NativeScript have some gotchas you need to keep in mind. How many you hit depends on how deep you go, but there are definitely some.
When to Use It
Ionic is great if you want to create quick prototypes or a quick mobile app version of your website, and don't need a performance beast. It's also great for reusing as much code as you can between your web and mobile app.
If your company is primarily a Vue.js or Angular development company, you're effectively choosing between Ionic and NativeScript.
NativeScript
NativeScript (originally called Telerik NativeScript) enables developers to create truly native mobile applications using JavaScript or TypeScript. Unlike Ionic, it does not use WebView but accesses native APIs directly. If you know you will need plenty of third-party libraries, NativeScript isn't for you. The community isn't huge, and it likely won't grow; at least nothing indicates it will. A huge pro is that it has first-party integration with many frameworks.
When to Use It
NativeScript is the least popular of the 3, but it's still not a bad option. You will have significantly fewer third-party plugins and libraries at your disposal, but maybe you won't mind. Furthermore, it offers integrations with 6 different web frameworks, not counting the option of vanilla JavaScript & TypeScript.
If your company primarily uses Vue.js, Angular, Svelte, or Solid, go for it. If you know ahead of time that you won't be using many third-party UI components and such, it's safe to pick. If you do expect to use them, consider a different framework.
React Native vs Ionic vs NativeScript
While choosing the tool matters less than other business decisions, it's still an important decision that could make or break your project. Depending on the type of your app, it can have a big impact on the user experience you deliver.
User Experience
React Native provides a truly native look and feel, as it uses native components for rendering. This results in smoother animations and transitions, making it ideal for performance-sensitive applications.
NativeScript also offers a native experience, allowing direct access to native APIs, which can enhance the app's responsiveness and overall user satisfaction.
Ionic, while capable of creating visually appealing applications, often resembles mobile websites more than native apps because it relies on WebView. This can limit performance in complex applications, and the user interfaces look similar to native ones but feel slightly off.
Development Speed
Ionic is generally faster in development for developers familiar with web technologies (HTML, CSS, JavaScript), making it a preferred choice for rapid prototyping and simpler applications that aren't performance critical.
React Native and NativeScript may require more time to master due to their more complex setups and the need for understanding native mobile development concepts.
Performance
React Native and NativeScript are designed for high performance close to that of native applications. If you're developing graphics-intensive, complex applications, choose one of these two. You should also choose one of them if smooth 60 frames per second is a priority.
Ionic, while effective for simpler apps, can struggle with performance under heavy loads or when utilizing extensive animations.
Community and Ecosystem
Both React Native and Ionic have large communities with plenty of resources, libraries, and third-party plugins that can speed up development.
NativeScript has a smaller community but still offers useful resources and support, particularly for developers who want to use native capabilities.
In the 2024 Stack Overflow Developer Survey, 9% of professional developers declared they're using React Native, 2.8% declared they are using Ionic, and... NativeScript wasn't there. According to the same survey, 56.5% of professional developers "admired" React Native, while 39.6% "admired" Ionic.
When it comes to popularity on GitHub, React Native's repository has 119k stars, NativeScript's repo has 24.2k stars, while Ionic's has more than double that with 51.1k.
Cross-Platform Compatibility
All three frameworks allow for cross-platform development, but the extent of code reuse varies. React Native and NativeScript can share a significant portion of code between iOS and Android. Meta's mobile app framework has one significant pro: you may also create desktop apps for macOS & Windows.
Ionic allows broader code reuse across web, mobile, and desktop platforms but may require additional adjustments for optimal performance on mobile phones. Keep in mind that desktop apps created with Ionic are based on Electron, which is great for development speed but uses too many resources. For example, Slack, a popular messaging app, will easily use 500 MB of your RAM without breaking a sweat.
Summary
The three frameworks approach mobile app development differently, each catering to different developer groups and companies. React Native focuses on creating high-performance, native-like applications using React only. It's ideal for teams & companies familiar with React that want to use native capabilities. Ionic uses web technologies (HTML, CSS, JavaScript) to build hybrid applications that run in a WebView. It's best for rapid prototyping and simpler applications where development speed matters more than native performance, and it's great for web developers moving to mobile. Performance can be a limitation for more complex apps, but it is very accessible for web developers. Lastly, NativeScript provides a way to create truly native apps using JavaScript or TypeScript, accessing native APIs directly. It's suitable for applications that make extensive use of native features, and while it offers a good balance between performance and flexibility, it may not have as large a community or ecosystem as React Native or Ionic.
The choice among React Native, Ionic, and NativeScript should depend on your project requirements, team expertise, and desired user experience. Each framework has its own strengths and weaknesses and its own ratio of development time to UX, so understanding your goals will help you make the best decision for your mobile app.
For us, as well as for a large portion of other companies, there is no better choice than React Native. We love React, and we have created apps using both the native version and the web one. If you need an experienced React & React Native development company, feel free to contact us. You can also see our Expo setup on GitHub.
