React Native: Build mobile apps with javascript

While ReactJs is a web front-end framework, React Native has been designed for app development. To give you a brief overview of React Native and the To begin with the application of this framework, let’s start with the question of what React Native is.

What is React Native?

In one sentence, React Native is a framework for building mobile applications using Javascript and the React Library. Similar to frameworks such as Cordova or Ionic, React Native pursues the approach of providing multiple platforms with one codebase.
However, this is a big and crucial difference to all these so-called hybrid
Frameworks. Unlike many other frameworks, React Native does not use a webview to make an app native to the smartphone, but converts the written JavaScript
and JSX in native code for each platform. This results in some advantages, which I emphasize below.
React Native already has some of React’s concepts, such as the components, the states, the lifecycle methods, and more. Therefore, it is also easy to fi nd into React Native if React is already mastered.

Benefits of React Native

A codebase, many platforms
Because React Native with a codebase supports several different platforms like iOS and Android, it can save a lot of developer resources. In addition, it is no longer necessary to create multiple projects for each platform, but one project can serve any mobile operating system. This greatly facilitates the development, maintenance and distribution of such an app.

Speed ​​and performance

Because React Native is not a hybrid framework that only uses a Webview to run code on multiple platforms, but converts JavaScript and JSX to native code, it also has an impact on application performance. Here, an app programmed with React Native scores significantly better than a hybrid app developed with Cordova or Ionic. It also makes the look and feel native, whereas a hybrid app often does not feel native.

Well-known development language

An advantage of React Native is not just that it needs only one code base for multiple platforms. Also, the chosen language is another plus. Because almost every developer has ever been concerned with JavaScript, which of course makes getting started much easier.

Disadvantages of React Native

featured

React Native has already integrated some native smartphone features, which have one
certain API can be addressed. However, not all features can be retrieved so far, as is possible with native apps. Although these functions can be extended by native modules, it is relatively complicated and not that easy.

New framework

In addition, a previous disadvantage of React Native is that this framework is so new. As a result, the documentation is not as detailed and mature as other more widely used frameworks. This relatively new and small community also adds new features slower than others do. That’s how it takes
for example, until now relatively long, until new SDKs of the platforms are integrated and the old become again.

When should React Native be used and when not?

The still relatively new framework is becoming increasingly popular and more and more used by larger companies. Instagram, Netflix and AirBnB use React Native. But when should you consider using React Native as the app creation framework?
It depends entirely on your circumstances and resources. If an app with not too much functionality and a short period of time to develop must be created, so
offers React Native. However, if your app has more special features that React Native does not support, then it’s often better to opt for a different solution or even native development.
