WHY USE REACT NATIVE TO PROGRAM YOUR APP

WHY USE REACT NATIVE TO PROGRAM YOUR APP?
At first, like most people, I was skeptical of
using Facebook's React . Demos of the extension
of React Java Script programming language, JSX
made some developers uneasy. For years, people
worked with HTML and Java Script separately
until React seemingly combined them. Some also
questioned whether it was necessary for there to
be another customer-based library in all of the
existing libraries. If you're interested in

EVERYTHING FOR APP APP Development and
Associated Costs As it turned out, React proved
to be the best solution for our own projects as
well as for our clients. Even companies like
Netflix or Skype use React. With React Native,
the framework is also perfect for app
programming. React Native is a great alternative
for developing perfomance-strong apps that feel
at home on both Android and iOS. Now I come to
give you an overview of the framework and to
report on my favorite features. React is
described by its developers as follows "A
JavaScript library for building user interfaces",
React puts its focus on the view of the
application. That is, when writing a React code,
the displayed code will be written React
components, which are small parts that describe
how the App will look like. Consider a small
example that can be used to display a simple
button. const Button React.createClass (
2
propTypes onPress React.PropTypes.func.isRequi
red, text React.PropTypes.string.isRequired, ,
render () return ( ltTouchableOpacity onPress
this.props.onPress style ...gt ltText
style ...gt this.props.text lt/ textgt lt/
TouchableOpacitygt ) ) This button
component has two parts of Input Data onPress,
which is a callback function in case the button
is pressed and text, which is responsible for
the view of the button. The XML-like structure
is called JSX, which is syntactic sugar for React
function calls. And TouchableOpacity and Text
are existing components that React Native
provides. After the creation of the Button
component, it can be used again and again in the
application, with recurring style and behavior.

This simple example demonstrates how a React app
is built. "Piece by piece." Even though the app
grows in function, the individual components
remain understandable and manageable at every
level. NATIVE VS HYBRID APPS. WHAT SHOULD YOU
CHOOSE IN 2017? Truly Native Most apps written
with JavaScript use Cordova , or a framework that
builds on it, as well as the popular frameworks
Ionic or Sencha Touch . But no Cordova App will
ever get the feel of a real native App.
Scrolling, keyboard behavior and navigation can
bring frustrating experiences if they do not
work as expected. Even though JavaScript is still
written in React Native, the components are
rendered as Native Platform widgets. And if
you've written apps in Java or Objective C,
you'll spot some React Native components right
away. Ease of learning One of React's biggest
strengths is reading comprehension, even for
programmers who have not worked with it yet. Many
other frameworks first require you to learn a
long list of concepts that have nothing to do
with the language building blocks. As an
example, let's compare the difference between
rendering a list of friends in React Native and
Ionic (Angular JS) Ionic uses ngRepeat
Directiv. Let's assume we have an order for
friends. Each field contains the following
fields first_name, last_name and is_online. But
we only want to show them, which are currently
online. Here is our controller function
FriendCtrl ( scope)
4
scope.friends first_name, John ',
last_name 'Doe', is_online true, , first_n
ame, Jane ', last_name 'Doe', is_online
true, , first_name, Foo ', last_name, Bar
', is_online false,
5
And here is our view ltdiv ng-controller
"FriendCtrl"gt ltUlgt ltli ng-repeat "friend in
friends filter is_online true
"gt friend.last_name, friend.first_name lt
/ Ligt lt/ Ulgt lt/ Divgt But if you are unfamiliar
with Ionic / Angular JS, you can directly ask
yourself a few questions. What is scope? What
is the syntax for a filter? And how can I add
more behaviors, such as sorting the friends
list? With React Native, one can revert to
already existing knowledge of the language,
using the filter and map functions. const
DemoComponent React.createClass ( render ()
const friends first_name, John ',
last_name 'Doe',
6
is_online true, , first_name, Jane ',
last_name 'Doe', is_online true, , first_n
ame, Foo ', last_name, Bar ', is_online
false,
return ( ltViewgt friends .filter (f gt
f.is_online)
7
.map (f gt ltviewgt f.last_name, f.first_name
lt/ viewgt) lt/ Viewgt ) ) Since the main
part is normal JavaScript and only a few small
parts are different, React Native is easier to
understand for all programmers and is easy to
use even for beginners. React is also a very good
learning tool, if you do not know how to use Map
or Filter. React also brings you closer to these
functions. Developer experiences "Happy
developers are productive developers," and React
Native has a good developer environment. Instead
of constantly waiting for the code to compile
and restart the app every time you make a small
change, your React Native Codebase changes in
the running app. ( You can see a little demo here
). And if you've already worked with JavaScript,
you probably also know the Chrome Developer
Tools. While running React Native in Developer
mode, you can tie this to your desktop Chrome
browser, so you can use your debugger tools and
profiling tools at the same time. React uses
native flexbox for the layout . While every
layout engine is different, React Native's
support for flexbox means you can use the same
layout code for Android, iOS and web.

CODE SHARING We've already looked at how to use
code between iOS and Android via React, but can
do it on the web. Everything in React that is not
bound to a Native Component is already
divisible. Imagine an app that can be rendered
through servers, or through web browsers, or
Android or iOS, all powered by a shared
codebase. We're not there yet, but the community
is working to it, in unpredictable steps. Our
conclusion Due to the ease of development, the
quality of the apps, and the diversity of the
platform and its environment, our team at
Applaunch.io has always enjoyed the learning
process and development with React Native. If you
