Mobile devices generate more than 54% of network traffic worldwide.
App developers worldwide need to reach the mobile market faster than ever. Traditionally, mobile app development was done natively: one codebase per mobile platform. The first attempts to make apps for different platforms from a single codebase consisted in just using HTML to make your website look like an app.
However, many libraries and frameworks have enabled Hybrid Apps development in recent years. With the Hybrid approach, developers can generate, export, or run (depending on the particular solution) mobile apps on different platforms from a single codebase.
This article will look at hybrid app development with React Native.
What is React Native
Using JavasScript, React Native extended mobile app development to traditional frontend developers. Companies using React Native have a competitive advantage because it is easier (and less expensive) to find front-end developers than native mobile specialists.
React Native was initially built on ReactJS (also developed by Facebook). Despite being completely different solutions, they share many philosophical aspects and design principles (ReactJS generates HTML5, JavasScript, and CSS, intended to run a web browser).
A crucial aspect of React Native is that it is a declarative framework. Declarative programming means the developer focuses on describing the components instead of telling the framework what it should be doing. Generally, declarative programming enables better development time and is less error-prone.
Similar to what happens with ReactJS, React Native developers have faster development cycles. By hot-reloading, developers can see their changes in seconds instead of building and deploying a native app each time. The improvement in development cycle times is dramatic.
How React Native enables cross-platform development
Mobile applications generally have a user interface and a logic backend that powers such an interface. The user interface consists of visual components such as buttons, input fields, drag-and-drop controls, and the like. Behind that interface lies a programmed logic that governs what happens when the user interacts with the visual components. Examples of such logic are data manipulation, API requests, and other processes triggered by a user's interaction with the mobile app UI.
Regardless of the inner workings of React Native, the final result is that a development team can code an entire mobile app using JSX and share that same codebase to run it both on iOS and Android. Previous generation products like PhoneGap or Apache Cordova (both discontinued) allowed this but at the expense of an inferior HTML5-based UX running inside a web view. With React Native, you get both a shared codebase and a superior platform-native user experience. This is the strongest argument favoring React Native and why it is so popular and demanded nowadays.
Improved mobile developers' experience
Developers using React Native can render their code changes almost instantly in their development environment. This is a considerable improvement compared to the compile-redeploy-relaunch lifecycle of classic native development. The difference in consumed time is massive.
When to choose React Native
In general, React Native is a perfect match for companies that need to go multi-platform as fast as possible. React Native is an excellent choice for startups using the Lean approach to develop their MVPs (Minimum Viable Products).
React Native also lowers maintenance and delivery efforts, thanks to a more agile development lifecycle, apart from speed and cost benefits. When building a mobile app from scratch, it is good to look at already available React Native modules to minimize the future chance of needing to program native code.
If a company considers outsourcing its mobile app development needs, it should look for outsourcing partners with a proven track record on ReactJs and React Native projects. The learning curve for inexperienced development partners can be pretty steep.
Some things to look out for when considering React Native
It is essential to have an objective view of any new technology a team might be considering adopting. Despite React Native's many strengths, there are some common pitfalls any development should be aware of.
As with any new technology, React Native is in constant evolution. This could pose a challenge for teams and businesses that need a more stable and mature technology. In addition, it is possible that your particular app still needs the team to write some native code. There has to be a careful balance between RN and native code if this happens. Otherwise, the drawbacks could overcome the benefits.
Another point to consider is if your app has to deal with massive amounts of data, impacting the overall React Native approach performance.
React Native is an open-source hybrid mobile app development framework. Like its cousin ReactJS, it is also developed by Facebook.
This framework can help a business reach a wider audience, simultaneously deploying a mobile app in iOS and Android. If the development budget is tight, which is usually the case for startups and mid-size companies, React Native is an excellent choice for launching on both platforms without double the development cost.
Several well-known companies develop their hybrid mobile apps using React Native, including Facebook itself, Instagram, Pinterest, and Skype, among many others. The number of top companies using this technology is a good indicator of future-proofing.
It is worth mentioning that Android and iOS native development is still the better choice if having a 100% seamless UI is critical for the product. Video Games, streaming apps that need background control, apps making low-level use of underlying hardware are examples of scenarios in which going native might be the best choice. However, the vast majority of mobile apps don't usually fall into these categories. React Native is a great option to achieve an almost-native user experience, with the benefits of using familiar languages for web developers.
React Native poses an exciting opportunity for developers, businesses, and tech companies that traditionally wouldn't consider diving into native mobile app development. It is a great technology and improvement enabler without sacrificing user interface smoothness and overall user experience impact. It is a relatively new technology, so it is essential to clarify that it is a work in progress, but the benefits outweigh the risks. The tradeoff is that it's new and still a work in progress, although many teams consider this challenge empowering and arrive at outstanding results.
