React Native App Development

What Are The Pros and Cons of Choosing React Native in 2021?

React was introduced two years ago and comprehending its capability since its inception, React is being used by Facebook for developing new projects till date. 

React enables the IT professional service providers to focus deeply on their projects instead of searching for a reliable and adequate framework.

How Does React Help You?

React has assisted the community of developers by leveraging them to simplify the programming models. It has given space to raise the level of abstraction and build predictable code with confidence. 

As a result, the dedicated software development team was able to craft better and scalable products, inclusive of Facebook components. Moreover, some of the amazing frameworks in JavaScript, such as Relay, are used on top of React for quick and easy data fetching. 

However, building apps for different platforms is one of the challenges for React Native application development. There are other challenges with React Native that are discussed below, which are somewhat resolved.

React Native Initiatives That Progressed With Time 

React Native's first successful application could be underlined as the Ad Manager app for Facebook, which was an initiative to leverage the employees to manage their accounts and create new ads simultaneously.

Developing an iOS Ad Manager App 

This achievement led to the foundation of a new cross-platform app. The Ad Manager was first crafted for the iOS platform, written in Objective-C, which when successful was later written in Java for Android devices compatibility.

Libraries for Successful React Native App 

With the help of iOS and JavaScript libraries, React Native app could be easily bundled to perform some of the major functions, such as crash reporting, authentication, analytics, push notifications, networking, and internationalization & localization. 

With the help of JSON and Relay libraries, the requisite frameworks can easily deploy files to the React applications.

Navigator and Interaction Manager Components

To navigate the flow of existing ad and campaign the most essential component needed is the Navigation Component. This component links effectively with the UI components to navigate the features and presents an expected result. 

The component leverages regular views & breadcrumb of ads and campaigns. Although, the component is linked with JavaScript libraries to perform the relevant task. Hence, the thread of the JavaScript frame mustn't be blocked. 

The large flow of the data and its processing can certainly slow down result efficacy or block JavaScript threads. Here, the ultimate savior is the Interaction Manager. Interaction Manager can easily interact with bundled components that can further process the data in the background quickly. 

As a result, the animation reciprocated on an app screen is the background hard work of Relay components rendering React components with the help of JavaScript and others.

Deploying an Android Version 

When an Ad Manager for iOS was developed effectively, the product engineering services provider went on to develop an Android version of it. 

Here the hard work was reduced to 20% as 80% of the development code for Android as iOS code could be easily used. Since the design and features were similar, only then this leverage was taken.

However, in order to do that React Native's packager block and abstraction mechanism feature were the first to help. 

These features helped in refracting the platform-specific parts of the UI into separate components, hence android app development was possible using iOS code compiled with React Native components.

An Android and iOS repository was also developed to help especially those developers who have always worked on JavaScript. These repositories store the source code for both operating systems with respective libraries to extract them when needed. Developers today can easily extract code and make changes & test them as required without the need for writing or learning native code from scratch. 

How React Native Can be Difficult to Work With?

As aforementioned, mobile app development on different platforms is one reason. Other than it, 

  • React Native made it hard to automatically layout things out of the screen. Hence the developers or designers had to manually size and position the views. The native mobile environment had also slowed down the development velocity due to the slow transition to mobile. 

React, on the other hand, makes website development quite easy allowing web developers to save and reload files on the browser and quickly see the changes. But, this is the opposite in the React Native environment.

  • Developers have to recompile, whether it is simply shifting the pixels on the screen, resulting in lots of time consumption, when it comes to compiling a large code. 
  • Testing was also challenging and burdensome on React Native. Earlier, for testing Facebook on the browser, each version was tested twice and the result could be obtained immediately.

The testing of the mobile version of Facebook was challenging, qa testing service providers had to wait for a week or even months for results. 

These struggles were the cons of developing applications on React Native. Where the browser version was easy to develop and results could be fetched quickly, the application took longer development time as well as A/B tests results demanded to stay put. Due to which the new versions were impacted and fewer releases were declared.

What Else Can Create An App Worsening While Using Native Environment?

Syncing resources from the native environment to JavaScript was tricky. The entire code or programming model had to be fundamentally changed to ensure that the systems, where the models are migrated, must pass messages asynchronously. These messages later had to be batched to minimize cross-thread communications for less confusion and chaos. 

This improvement in the system was made recognizing the system lock every time during movement, which had adverse impact on the user interface of the app. 

Moreover, the native environment had some overhead fixed with every trip made for migrating the UI programming model. Crossing over the thread boundary each time automatically brought a painful overhead. 

Why Should You Pick React Native for App Development?

Despite these disadvantages, React being the base, has always assisted React Native for further improvements and scalability of the app development.

The unique features that captivate any designer/ developer to use native for mobile app development service  were available in the form of React Native components. There are various advantages of implementing native components to produce better user experiences on mobile than on the web. 

Power Packed UI Components and Multiple Thread Alignment

React Native offers access to its UI components, such as maps, data pickers, navigation stacks, switches, and much more, which can be reimplemented on the web. However, you will never find the same look and feel and the components will not get updated automatically. 

Additionally, React Native gives you intuitive gestures & tools for mobile apps, which you won't find in web-based React.  

React Native gives you a sophisticated thread model to streamline and align multiple threads. Other than these, native models can perform highly numeric computation, like text measurement or decoding images very efficiently. 

Advancements that Envision Successful React Native Development Services 

A combination of developer experience and user experience can help in developing the right mobile app. Features that can be ingrained to achieve the best app experience are:

WebViews

Developers can integrate WebViews within a Native wrapper. The approach for using Webviews is flexible and only an experienced web developer can associate with it and take full advantage of the React and web's rapid iteration cycle. 

Porting to Native

The React can be ported to native code to create a brilliant iOS app. The open-source ComponentKit leverages some of the best components, such as declarative & predictable UIs compiled with the native's environment. 

The compilation of some extensive features of the native environment, such as sophisticated gestures, asynchronous image decoding, text measurement, & rendering and much more can assist in developing and maintaining the code easily. Another best part about porting React to React native code is the use of flexbox that lets you automatically position and size views in-app. 

Scripting Native

With access to all the native environments, you can easily call into the Native APIs. Additionally, access to the JavaScript infrastructure will give you leverage to quickly iterate the code. 

Embedded JavaScript Core Instances

Running this instance in an app can help in rendering higher-level platform-specific components. The best part about the instance is, it provides the power to build new products on top of it. Moreover, it allows conversion of the old products so that you do not need to rewrite an entire mobile app from scratch. 

Support for Hermes

React Native's recent release supports the open-source JavaScript engine. This feature is deployed for iOS and only supports this OS. This optimization not only improves the performance, but also reduces the download size, the time it takes for an app to become useful, and memory utilization. 

Hot Reloading

The idea to release this feature was for the app to continuously run and inject new features even during the runtime. The Hot reloading is built on the top of Hot Module Replacement or HMR. The HMR contains the JSmodules code. When an updated HMR is released, the old modules can be easily replaced with new ones. 

  • HMR API - Hot Reloading works out of the box in the common cases with the help of HMR API that extends the module system to introduce objects as 'Hot'.
  • HMR Runtime - The whole HMR doesn't simply update with API, the runtime is equally essential to clear the export of the log in order to make any new changes.
  • React Components - React Components cannot be freely used with Hot Reloading. With the help of proxy, the component's state can behold and further delegate them to the lifecycle methods to actual components without losing any app's state. 
  • Redux Stores - In order to render HMR updates, HMR API is essential, which can help in searching for the right module to accept the reducer and make changes or updates as required.

Support to Flipper

A brilliant tool for developers to debug mobile apps, which is most popular in Android as well as iOS communities. Flipper enables the developer to -

  • Reload the app and trigger the Dev Menu.
  • View Crash Reports
  • Use the latest version of ReactDevTools
  • View all network requests
  • Filter, search, and view call logs.
  • Edit and view Native layout
  • Edit as well as view the database and preferences of the device.

Additionally, the extensive features of Flipper are -

  • New Dark Mode
  • Bringing Apple TV in line with other platforms.
  • New upgrade support to change into a newer version of React Native.
  • LogBox error and warning experience.
  • Improvements in Accessibility, such as accessabilityValue, missing props on Touchables, Switch components, and accessibility events.
  • Removal of proptypes from core components.
  • Deprecated accessibility States removal.
  • TextInput removed.
  • Deprecated AccessibilityInfo.fetch.

Support For LogBox

The latest release of LogBox is to analyze the types of errors and warnings, which is also among the biggest problems today. To address all the issues and make debugging easy in React Native, the latest LogBox helps you redesign the experience. The LogBox addresses -

  • Logs with minimum information.
  • Logs formatting to quickly find the requisite information.
  • Actionable logs to quickly fix the issues.

Hence, the current version of LogBox provides -

  • Redesigned warning notifications.
  • Code frame for each error and warning.
  • Stripped component stacks from error messages.
  • Default call stack frame collapsing.
  • Improved syntax error formatting.
  • New core component ‘Pressable’, to detect distinct interactions. 
  • Dropping support for Node.js 8 and iOS 9.
  • Render any ‘view’ inside a ‘text’ component without size explicitly.
  • React native template compatibility through Xcode storyboard.

In a Nutshell -

React Native has taken the GAAD pledge in order to make this open-source project more accessible and secure. Ranging from the Native API accessibility to the core components, the community is focused on bridging the gap necessary for an exceptional user experience. Hence, the ever-enthusiastic and vigilant community for enterprise software development services is always looking forward to contributing in addressing the root cause of the issue and finding innovative ways to deal with them. So the changes mentioned above are the result of their progressive efforts and will continue to offer throughout the time.
