New React Native Architecture- Value Offerings and Improvements in 2020!

New React Native Architecture- Value Offerings and Improvements in 2020!
React Native, ‘the minimalistic JavaScript framework’, was actually discovered as a side-project while working on ‘React.js’- Facebook’s another important project. The principal motive behind React Native’s discovery was to find a comprehensive solution for creating cross-platform applications with native properties.
But surprisingly, this framework became way more popular than anyone thought, despite having some flaws. To make it more powerful, it was strongly backed by the huge open-source community of Facebook. Also, in the year 2018, the Facebook team announced the re-architecture of this framework for addressing all the existing issues faced by engineers during React Native development. Today, React Native has become one of the most preferred choices of developers for creating modern-day SPAs and mobile apps.
React Native is still progressing and a host of React Native development companies have emerged across the globe, due to a massive demand for this framework.
So what’s new in React Native in 2020? Well, the framework is about to release its new architecture in the market. In this article, we will have a glimpse at React Native’s enhancements in 2019, the basic React Native architecture, and its new update in 2020.

Highlights of the React Native in 2019

In 2019, React Native introduced several versions with some amazing modifications and tools. Let’s explore them.
Updates in Version 0.60
  • For speeding up the development of the repositories, the team moved the main packages to distinct repositories
  • The start screen was modified and made more informative
  • Android X was introduced. Facebook also released a JavaScript engine which was optimized for React Native, Hermes. Hermes enables Android apps to use lesser memory, faster launching and apps are much lighter in size.
  • The helper was updated too after a long time
  • Auto-linking of the native modules, another new feature was introduced
  • CocoaPods were merged as a section of the React Native IOS project
Updates in Version 0.61
  • The hot-reloading and live-reloading features were replaced by the well-functional Fast Refresh feature.
  • Another significant feature- React Native doctor was launched in this version which ensures that migrations and updates become hassle-free.
Updates in Version 0.62
  • The team announced that Flipper, a feature that enhances the debugging of mobile apps in both- Android and iOS, will be introduced.

Overview of The Old React Native Architecture

Main objective of this framework is to help React Native developers to write JavaScript React code so that UI can be displayed correctly at the same time developer can access the native capabilities in the app. Mechanism for Android/iOS ecosystem typically looks like this:
There are 3 threads running in parallel in the React Native apps like JS thread, Native thread and, Shadow thread.
JS Thread is where the code of JavaScript is read fully and then compiled. Here the business logic of the app also resides.
Shadow Thread does the layout calculation. It makes use of Facebook’s layout engine named Yoga for calculating flexbox layout and then sends this information to the UI thread.
Native Thread does handling of the user interface. When the app needs to access native capabilities or UI needs to be updated, communication takes place between this thread and JS thread.
In this older architecture, C++ Module Bridge had to be used to make the communication possible between JS thread and Native. Every time data received from JS thread or Native had to serialized as JSON and then had to be sent to the queue and then after arrival had to be decoded. Due to the bridge that is being used for communication, there was an inherent delay in the synchronization between the native and JS code.

Highlights of Re-architectured React Native Framework in 2020

To address some of the existing issues related to the bridge in React Native, Facebook has taken the important step of going for a revamp in the architecture of this framework. There will be enhancements done in the Native Modules. For instance, a Type-safety feature would be introduced for improved safety between JavaScript and Native-side code. There will be default lazy initialization of Native Modules for faster startup. Also, when calling native methods from JavaScript, there will be less overhead. It will be possible to control the Native Modules directly. Communication between different threads will improve considerably.
Also, there will be the implementation of a new thread-safe of the React Native UI layer. It will help in better native interoperability, faster startup, elevated UX of core components, etc.
Another update will focus on a new set of APIs for the initialization of React Native. It will be dependent on the new native module system and the new renderer. The overall aim is the improvement of the startup time.
JavaScript Interface- JSI will be another important update that will be useful during native development. For this, the Bridge feature will be deprecated gradually. JSI act as an enabler for TurboModules and Fabric. Now, the JS bundle can make use of any JavaScript engine and is not limited to just JSC. The JSC engine can be replaced with a JS engine like V8 for instance.
JSI helps in the following:
  • In loading JS bundle
  • calling functions between JS and C++, creating JS runtime
  • for creating and accessing JavaScript objects from C++
Also, JS can now hold the reference to C++ Host Objects and call methods on them with the use of JSI. This will ensure that the Native and JavaScript realms will be aware of each other. So we can say that complete interoperability will be possible between all threads. Also, React Native developers will now be able to handle very large panels of systems.
A concept of shared ownership is being introduced in this new architecture which allows the JS code to directly communicate with the native code from the JS thread. So the serializing to JSON the messages won’t be required to pass across and all the asynchronous issues, congestion, etc. on the bridge would be removed.
This architecture also allows better control over native modules as developers can use native modules when the need arises instead of loading all of them at the startup. Consequently, there is a huge performance improvement during startup.

Final Words:

Since its inception, React Native has accumulated several features and functionalities that have become redundant today. So, to match the needs of next-gen apps, and other software products, the framework is cleaning away the unnecessary and outdated sections. This new architecture is an attempt to make the React Native development services highly efficient to create performant apps. Some features have even been replaced by their advanced counterparts. The core modules like AsyncStorage and Webview have been gradually removed and changed into the community managed repositories.
Besides this update, the React Native developer tools will make the development process much easier and impactful. All this is going to help the React Native developers a big time in improving the overall work-flow, time-frames, development process, predictability, reliability, and much more.
The re-architecture of React Native is expected to get completed in the coming few years and the future of this technology definitely looks bright.

Ionic vs Flutter: A useful guide to app creators!

Ionic vs Flutter: A useful guide to app creators!
The digital revolution has gifted the software industry with a plethora of outstanding app development frameworks. As a consequence, choosing the right framework for app development has become a herculean task for app creators. Ionic and Flutter are two such frameworks that utterly confuse the app creators striving hard to pick a framework for architecting cross-platform applications. Picking one out of these frameworks becomes all the more intriguing since they appear quite similar, but are in reality way different from each other. However, both Flutter and Ionic app development come with novel offerings and cater to specific project requirements. Hence, you need to be well versed in their similarities as well as differences to pick the right one.
This blog compares Ionic and Flutter based on certain parameters, to provide the entrepreneurs with clear visibility about their strengths as well as drawbacks and help them decide the perfect pick for their project.
Before we move on to compare Ionic and Flutter, let me provide you a brief introduction to these frameworks.

Introducing Ionic

The Ionic framework was coined by Ben Sperry, Adam Bradley, and Max Lynch of the Drifty Co. in the year 2013 and its first stable version was launched in March 2014. Ionic is an open-sourced UI toolkit that uses web technologies like JavaScript, CSS and HTML; to architect top-notch desktop, mobile and progressive web applications. Ionic primarily focuses on the front-end UX and UI interaction and hence plays a vital role in handling the look and feel of an app. Not only is it capable of easily integrating with other frameworks and libraries like Cordova, Angular, etc. but also can be used independently without the support of a front-end framework.

Introducing Flutter

Flutter, Google’s brainchild, is a relatively newer framework as compared to Ionic and is still evolving. It was created in May 2017 and is currently managed by Google with the help of an ECMA standard. Flutter is a UI toolkit that employs Dart programming languages to build swift, attractive and natively compiled cross-platform apps. Flutter was introduced as a Software Development Kit (SDK) intended to build modern apps for Android and iOS. In the case of Android Studio, integration is done with inbuilt Java,and Swift and Objective C integration is done in the case of iOS.

Similarities between Flutter and Ionic app development services

Flutter and Ionic may be way different from each other but share certain similarities too. They are as follows:
  • Both build cross-platform applications that run on desktops, mobiles as well as the web.
  • Both employ a single codebase to create interactive and high-performing apps.
  • Their primary focus lies in creating UI frameworks for native platforms. Both impart an incredible native look and feel.
  • Both frameworks have a well-organized documentation for developers.

Differences between Ionic and Flutter app development services

Now let’s explore the differences between Ionic and Flutter based on the following parameters.
Skillset: Market value
The skillset required to use Ionic involves learning JavaScript and other general web technologies that are needed for any web app development project regardless of the framework used. But, learning Dart for using Flutter will not prove useful for projects involving other frameworks. Moreover, owing to Flutter’s highly-custom environment, developers need to master certain unique methodologies that are time-consuming and applicable to Flutter app development only. Furthermore, the requirement for Dart developers in the coming years largely depends on whether the newbie Flutter, will succeed as a viable solution in the future.
Hence, acquiring an Ionic skillset proves to be a safer bet for a developer.
Portability of the code
Let’s have a look at how the codes of Flutter and Ionic behave in various eco-systems, OS and processors. Flutter development leads to the creation of visually appealing Android and iOS apps. It is a great choice for mobile apps but encounters limitations when deployed on the web. Ionic, on the other hand, creates fairly good mobile apps and exceptionally good web apps. Therefore, if you are planning to build PWAs or web apps, picking Ionic is advisable.
User Interface
Flutter has attractive user interface in comparison to Ionic because Ionic uses HTML and CSS for rendering. Flutter has widgets as part of UI elements whereas Ionic has Web Components.
Flutter fares well if your application requires exclusive animation whereas Ionic serves better if you intend to architect an app that is more consumer-facing. Ionic employs primitives and the runtimes of the standard browser, hence the bundle size is 2991 bytes whereas Flutter requires a heavy code for building even a basic application.
Flutter users Dart language and since it does require JavaScript Bridge for interactions between the app, the performance is far better. For rendering Ionic uses Web technologies, hence the performance is much lower.
Mobile performance is better in Flutter in comparison to Ionic. Web performance is poorer in Flutter than Ionic.
Free usage of libraries
The Flutter app developers can use Flutter’s libraries and system technologies free of cost. In Ionic, several libraries are free but a paid Pro Development Environment is needed for speeding up the developmental cycle.
Community support
As far as community support is concerned, Ionic surpasses Flutter. Flutter being a newbie lacks strong community support while Ionic enjoys the support from a dynamic global community that assists Ionic app developers to solve problems. However, owing to Google’s continual effort, Flutter also may develop a vibrant community in the years to come.
Now let’s discuss these frameworks from the perspective of the flexibility and freedom offered once the app matures. Flutter app development may turn out to be a bit risky. The reason is, if by any chance Google shuns Flutter, a Flutter app Development Company will be left with a code base and skillset that are homeless, though such a situation is least likely. Ionic app development on the other hand is based on open web standards and relies on web components. So, it can be used with any existing JS framework or compatible future framework if the app creators choose to create apps for other platforms or use the code for other projects.

I hope this blog has enlightened you about how the custom-based approach of Flutter differs from the web-based approach of Ionic. Both of these cross-platform app development frameworks are distinctive in their way. Therefore, whether to opt for an Ionic app development company or a Flutter app development company solely depends on your project requirement.
