1. When to choose and avoid react native for mobile app development?
What Is Mobile App Development?
Mobile application development refers to the methods and techniques involved in developing
software for compact, wireless computing devices such as mobile phones and other hand-
held gadgets.
Mobile application development, like web application development, has its origins from
earlier software development methods. Mobile applications, on the other hand, are frequently
designed specially to take the benefit of the unique capabilities of a particular mobile device.
A game software, for example, might make use of the smartphone's accelerometer, while a
mobile health app could make use of the temperature sensor on a smartwatch.
Apple's iOS and Google's Android are the two most popular mobile systems currently. Apple
phones and tablets come equipped with key apps, such as a complete web browser and
access to the Apple App Store. Similar applications come preinstalled on Android
smartphones, and you can download more from the Google Play Store.
Apple and Google both offer their own set of development tools, UI components, and SDKs to
app developers. Most businesses will engage in native mobile app development due to the
numerous advantages it provides over other types of applications such as hybrid or web. Since
mobile software is becoming more and more of a necessity for businesses, it's critical for them
to understand the benefits and drawbacks of various app development approaches.
What is React Native?

2. React Native (often referred to as RN) is a renowned JavaScript-based mobile app framework
that is used to create completely rendered iOS and Android apps. Using the framework,
developers can build applications for a variety of platforms with the same source. Facebook
originally launched React Native as an open-source project in 2015. It became one of the most
popular mobile development solutions in just a few years. Some of the world's most popular
mobile apps, such as Instagram, Facebook, and Skype, use React Native development.
React Native's worldwide success can be attributed to a number of factors. To begin,
businesses can use React Native to build code once and use it to power both their iOS and
Android apps. This saves a lot of time and money. Second, React Native was developed on
top of React, a JavaScript library that was already well-known before the mobile framework
was introduced. Furthermore, the framework enabled frontend developers who could earlier
just deal with web-based tools to construct sophisticated, production-ready mobile
applications.
React Native, like many ground breaking innovations, was created in reaction to...a major
technical blunder. It has been embraced by hundreds of companies around the world,
including Uber, Microsoft, and Facebook, and it is utilized in a variety of sectors. However,
before you decide to go all-in with React Native, you must first learn how it works and
determine whether it is the best match for your project. What are the most significant benefits
and drawbacks? What makes it unique among other cross-development platforms? Last but
not least, what should your developers be aware of before embarking on the React Native
adventure?
We'll address these and other questions in this blog so you can make an informed decision
about whether React Native is right for your company.
When to choose to React Native?

3. When you need to design a mobile app that works on a variety of platforms, React Native is
the way to go. It saves developers time by providing pre-built components and code that may
be reused across platforms. React Native is mostly used for mobile development; however,
you can use React Native for Web, which uses React DOM to execute React Native
components and APIs on the web.
Yet, ReactXP, a Microsoft cross-platform development framework, is the technology that's
most suited for this purpose. It integrates with React and React Native to simplify the process
even more by allowing much of the code to be reused across iOS, Android, Windows, and the
web versions of an application.
You must analyse the benefits and limits of React Native. It may be a good technique to create
apps if you have the correct use-case and development team.
1. To Create Personalized Design:
If you don't want the vanilla iOS and Android designs and instead want a customized design
that looks the same on all platforms, React Native is the way to go. For instance, if the business
or the product has a well-established design. Unlike other cross-compiling frameworks, React
Native implements native UI, but not everywhere you'd expect.
2. To cut the costs:
When the users want the logistical advantages that a hybrid framework delivers, such as a
single codebase and supporting development process, as well as cost savings.
3. To Create a Web App:
React Native is built on React, as the name indicates. As a result, if your app is built on React,
you can exchange code between your mobile and web applications, which is something other
frameworks can't do right now. You won't have to develop everything from scratch, but you
will be able to reuse some components and business processes, as well as have a single
development team that can handle both mobile and web development.
4. To make a prototype instantly:
Even if you plan to use native development to get a product to market, React Native is terrific
to get something up quickly. This might be a useful test of the framework's suitability for your
specific use case - perhaps native isn't required after all.
5. To Develop Only an App:
This is true for the vast majority of cross-platform frameworks. They're wonderful for creating
apps, but they'll be tough to use outside of that domain.
Platforms in an app provide a lot of flexibility for rendering other things, which cross-platform
frameworks take advantage of. However, outside of the app context, such as for battery-saving

4. purposes, there is less freedom. If you merely want an app and aren't concerned about
platform integration, extensions, or anything else, then it can be used.
When to Avoid React Native?
Let's take a look at a few of the React Native framework's drawbacks and why it's probably
not the ideal choice for building your project.
1. Apps created particularly for a single operating system:
Since there are so many apps designed specifically for Android and iOS, a React Native
application will always feel worthless to these apps, merely because it cannot deal with the
complexities of a native app. The performance of your app is determined by a variety of factors,
however, it has been proven time and time again that native apps outperform React Native
apps.
2. User interfaces that are complex to use:
If the application necessitates a great level of modification, and at any given moment, there
are several processes running in the background, it’s unlikely that they'd respond with React
Native. When compared to React Native, Native iOS provides considerably superior solutions
for developing complicated animations. Also, if your program requires the usage of a camera,
touch ID, GPS, or other features, React Native does not support them. As there are so many
differences between Android and iOS touch subsystems to be integrated into a single API,
developers may run into challenges when working with displays that use complicated motions.
3. Building services like battery monitoring:
When creating utilities such as battery monitoring, media players, antivirus, and so on, native
app development is considerably easier than React Native. This is because these apps always
make use of iOS's native capabilities and APIs.
4. Issues with the architecture:
Another significant disadvantage of choosing React Native is the lengthy setup process. This
is due to the fact that every Javascript code must be parsed by the JavaScript Virtual Machine.
When compared to binary loading, the start-up time will always be longer. Be careful of these
architectural challenges before digging into React Native to design your project.
5. The Abstraction Layer Problem:
On Android and iOS, an abstraction layer known as "the bridge" allows React Native to activate
the real rendering APIs. To add functionality to the native platform, this abstraction layer is
created on top of it. React Native as a framework also suffers from implementation difficulties.
Overall, if your project is built using React Native and relies on an abstraction layer, it's past
time to reevaluate your decision.

5. Benefits of Choosing React Native:
It will take a long time to create an application with native languages like Java, Objective-C,
and C#. And hiring an expert in these languages will set you back a small sum. So, what
options do you have in this condition? When it comes to developing your next mobile app, you
could pick React Native.
Let's have a look at why React Native is a good choice for mobile app development.
● Cross-Platform Development:
Once you've coded, you can use it elsewhere. Building cross-platform apps saves time and
money. However, remember that some platform-specific changes may still be required. One
codebase runs on iOS, Windows, and Android with React Native, each operating system
requires only a tiny percentage of the software to be changed. It also outperforms hybrid and
web applications in terms of speed and reliability.
● React Native Apps Have the Best Performance:
No other programming language, according to the developer community, can match the
performance of Native applications. React-native, on the other hand, behaves like native apps
and takes advantage of graphics processing units, which speeds up the apps. React-native
applications offer native UI components that increase performance and user experience. The

6. user experience is meticulously maintained and developed, which is why apps appear and
perform like native programs.
● Comparatively less usage of memory:
It is compatible with third-party plugins, and React Native technologies allow for a more fluent
run-time. The profitable architecture makes third-party engagement considerably easier,
thanks to its well-diversified components. It is possible to link the module to the plugin without
using Web View by using a native module. This stage is connected to the app's outcome
characteristics, which allow it to respond more quickly. Since cross-bridge linking is not
necessary and most of the scripts are utilized during run-time, React Native for iOS and
Android platforms consume significantly less memory.
● A Well-Designed User Interface:
Picker, Button, Slider, Switch, and other pre-built declarative components in React Native
allow you to construct distinctive, eye-catching UIs. You can also use Touchable Native
Feedback and Touchable Opacity to create your own components. Many iOS and Android-
specific components are provided to ensure that it runs well on both Android and iOS devices.
Conclusion
When you look at the benefits and drawbacks of React Native, it's clear that the benefits much
exceed the drawbacks. You'll notice a few small flaws. The disadvantages of this framework
are minor in comparison to the incredible benefits you'll receive. Other fascinating features
and benefits of this modern mobile application development platform include easy
communication between React Native and native, easy publication to Google Play Store,
ability to create for TV devices, and compatibility with existing apps.
React Native is an excellent choice for many businesses. However, if you demand absolute
performance or have a use case that necessitates it, Native may be the best option. Finally,
there is no antidote. When making such a crucial decision, it is necessary to think carefully.
