React Native Pros And Cons

React Native is a JavaScript framework for building mobile applications for Android, iOS and Universal Windows Platform.

Before you adopt React Native for your business or any other perspective, it is good to know about what are the pros and cons of this technology.

Pros of using React Native for your mobile application:

  • Fast development speed. You only have to build your app once using JavaScript. A purely native approach, on the other side, will require building two different apps (one for iOS and one for Android) from the ground up.
  • Same architecture as in the existing web application that uses React.js. If you have the web version, then around 90% of the logic you can use for mobile (listen to developers from Facebook, Skype, and others).
  • React Native perform as good as native apps do. It interacts with the native components for iOS and Android and renders code to native APIs directly and independently. In doing so, it uses a separate thread from UI, which results in increases the performance.
  • With native apps, debugging is a long and tedious process. But React Native supports hot reloading. It allows developers to immediately see how the changes to the code affect the app while it’s running.
  • Short team size. Having a single team vs having two different teams, an Android and an iOS team beat the later with potential better communication. Having a reliable JavaScript team on your mind, developers with React.js knowledge could quickly apply all the concepts for the React Native app.
  • Active growing community. There are a lot of additional packages expanding the standard library functionality, which are supported by enthusiasts and professionals who have the open-source code.

Cons of using React Native for your mobile application:

  • Dependence on Facebook. One of the RN’s weaknesses come from one of its biggest strengths. If one day Facebook ceases support of React Native, the framework would quickly fall behind both iOS and Android.
  • React Native has only a few ready-made components. Although it’s still a new development framework and that the number of ready-made components is expected to increase drastically, but at the moment the collection is quite small.
  • If you want to build a more complex application you might need to write a minimal amount of native code.
  • We mentioned the small collection of ready-made components. That is not a dead-end, as there are third-party component libraries that you can choose from. But that would depend on luck, in terms of quality and reliability of that specific library because they are not created by the official developers.

In conclusion, React Native is a framework cross-platform that has been well built and has achieved the goal of building a mobile app with excellent quality and performance. It is a great framework for small applications. Anything more complex will, most certainly, require more resources. But the rate at which the React community is growing, everything that could be holding this framework down, has high chances of changing. Especially as the component collection grows, it is highly likely that more advanced functionality will be introduced ant catered to.
