React Native is an incredible tool for building for Android and IOS native mobile apps. Hybrid development made the entirely new huge step forward in 2017 and now allows to create really smooth quality apps for both platforms where you won’t feel the difference if it’s hybrid or not.

React Native is made by Facebook engineers and they even made their Instagram and Facebook apps with this new technology which is one more proof of technology perspective.

We in Springs use React Native a lot, building apps for our clients.

Also we have experience creating our own custom React Native components or adjusting existing for our needs. One of such components was, for example, live face detection with totally different implementation for Android and IOS parts but with the same React Native API.

React Native Advantages

1. Faster to Build

The major selling point of React Native is shorter development time. It provides numerous ready-to-apply components that can accelerate the process. React Native still lacks some solutions, so you would probably have to build them from scratch. However, with the existing base of packages, you can save much time and it will only get better. As the RN community is growing and Facebook regularly introduces new updates, one day we may find a ready component for most of the solutions we need.

2. One Framework, Multiple Platforms

React Native enables copying the codebase (or just a part of it) between iOS and Android. In practice, full cross-platform development is possible to some extent, depending on how many native modules you use in your application. Some features will be available in apt packages, but others need to be written from scratch. It will only get better, though. React Native community actively supports the framework adding new tools to open source.

3. Hot Reloading

Thanks to hot reloading, a developer can keep the app running while implementing new versions and tweaking the UI. It makes changes in the app instantly visible without the need for the developer to save them. It is a major benefit for developers. Not only do they save time on the compilation, but also they don’t lose any state of an app while making changes. It boosts productivity and, in effect, the whole development time decreases.

4. Smaller Teams

Native development requires two separate teams for Android and iOS. It can hamper communication between developers and, accordingly, slow down the development. If you choose React Native, you will mostly need JavaScript developer who can write the code for both platforms. Obviously, apps with more native features will require help from native developers as well. Notwithstanding this fact, in most cases, the team will be smaller in size, and thus, easier to manage.

5. Fast Applications

Many argue that React Native code might hinder app performance. JavaScript won’t be as fast as native code, but in most cases, you won’t see the difference. We conducted a test and compared a simple application written in both React Native and Swift. Differences in performance were slight, almost unnoticeable to an average user. In the case of more complex applications, the framework might be less effective, but you can always transfer some code to a native module, and it is no longer an issue.

6. Simplified UI

React Native is solidly based on creating a mobile UI. In native development, it is necessary to create a sequence of actions in the application, whereas RN employs declarative programming in which such an order of implementing an action is obsolete. As a result, it is much easier to detect bugs on the paths a user can take.
