React Native 0.61: All-New Fast Refresh And Other Value Additions For Developers

Whenever we discuss cross-platform development, we need to mention the React Native 0.61 framework as one of the leading frameworks. Before cross-platform development became popular, developers had to struggle with several native technologies with which they were required to code separately for every different platform.

When a developer needs to build an app for both iOS and Android mobile platforms, they have to build two separate apps and develop everything separately from scratch for both platforms even though they are building the same app. This used to make the mobile app development process lengthier and complicated.

To do away with this time-consuming process, React Native came as a cross-platform development technology with WORA (Write Once, Run Anywhere) protocol creating maximum ease for app development across platforms. No wonder, for years, it has been one of the top 10 cross-platform frameworks.

A Background of the Cross-platform App Development with React Native 0.61

The emergence of the cross-platform app era presupposes all the challenges developers needed to face with conventional development methods such as using Native frameworks for developing native-looking hybrid apps.

They needed to code for each mobile OS platform separately.

When you hire React Native developers to build a mobile app across both iOS and Android platforms, they have to write the app’s code for both OS platforms from scratch while essentially developing a similar app.

WORA (Write Once Run Everywhere)

Thanks to React Native, this scenario took a complete turnaround. We got WORA (Write Once Run Everywhere) protocol to develop one app that can run on multiple OS platforms while still maintaining native user experience and features.

Who Developed React Native?

React Native, developed and maintained by Facebook, has instantly become famous thanks to its plethora of native features and high-performance functionalities. The reusability of maximum code for multiple OS platforms while ensuring native user experience through a native platform-specific layer is the core strength of React Native.

The acceptance and acclimation of React Native as a cross-platform technology was so outstanding that within just a year, it became one of the most loved frameworks in the thriving mobile app development scene.

But React Native is Not Flawless

But despite all these advantages, React Native has its share of pitfalls and shortcomings. These drawbacks often pull down the performance of React Native apps and mess with the user experience.

Here we list some of the notable persistent issues of React Native.

  • The upgrade from one React Native version to another is troublesome and time-consuming. It is incredibly tedious when the React Native version is too backdated, several updates are rolled out, and one tries to avail multiple updates at once.
  • React Native makes it troublesome to detect the principal cause of an exception. Often you end up landing on the ExceptionManager, which is not the original source. Even the componentDidCatch does not help much.
  • React Native offers a hugely popular feature called Hot Reload. Quite unexpectedly, it may not work well with Stateless Functional Components (SFC).
  • There are many occasions when React Native remains non-resilient to app crashes. Moreover, React Native often fails to give many insights into the reasons for crashes.
  • The ram bundle of React Native doesn’t get support from the OTA platform like CodePush. This becomes an issue just because React Native does not offer a well-connected community.

As already hinted, this is the most important key feature of the new version. It is fundamentally a combination of two pre-existing features, such as live reloading and hot reloading.  In this respect, it is essential to understand the impact of the Fast Refresh feature to React Native developers.

The latest Fast Refresh feature of the React Native 0.61 provides the below-mentioned advantages to the developers.

  • Fast Refresh fully supports current React projects that use Hooks and function components.
  • The feature is capable of recovering from common typos and other coding mistakes common to the developers. The most important thing is that the Fast Refresh can switch to Full reload whenever it is essential.
  • Fast Refresh completely prevents code transformations from its practices to ensure optimum reliability of code in default settings.
  • It has gone through stringent testing by the React developers and has been found as a genuinely reliable and tremendously flexible feature.
  • For the first time, Fast Refresh helped React Native developers to code appropriately for both functional components and class simultaneously.
  • Irrespective of the fact that Fast Refresh shares several attributes with hot reloading, it truly delivers better performance.
