1. Creating Beautiful
Apps with React
React Native is a powerful tool for cross-platform app development. In
this presentation, we'll cover the fundamentals of building beautiful and
responsive mobile applications using React Native.

2. Introduction to React Native
1 What is React Native?
allows for the creation of high-performance and responsive mobile apps for iOS and
Android platforms using a single codebase.
2 Why use React Native?
React Native simplifies the app development process by reducing the time and effort
required to build high-quality mobile applications. It also provides a range of features that
allow for the creation of beautiful and intuitive user interfaces.
3 What makes React Native special?
React Native uses a unique architecture allowing it to leverage the power of native
3. Advantages of React
React Native simplifies the
process of creating apps
for both iOS and Android
platforms. It allows
developers to code once
and deploy on multiple
platforms, thus saving time
and reducing costs.
React Native's unique
architecture allows it to
provide extremely high
performance, with apps
running natively on the
target device. This results
in faster and more
that provide a better user
3 Intuitive and Customizable UI
React Native provides a range of customizable UI components,
allowing developers to build applications with beautiful and
intuitive interfaces that are tailored to the requirements of the
4. Creating a New React Native
Initializing a new
The first step in building a React
Native app is to create a new
project using the "react-native
init" command. This will create a
new project with all of the
necessary files and directories.
React Native projects have a
clear and well-organized
structure, with separate folders for
code, assets and configuration
files. This makes it easy to
manage and maintain the project
as it grows in complexity.
React Native provides a range of
development tools such as React
DevTools, Redux DevTools and
more. These can be extremely
helpful in debugging and
developing your application.
5. Basic Components and Styling in
React Native ships with a
wide range of components
right out of the box, including
text inputs, buttons, sliders
and more. These can be
easily customized and styled
to fit the requirements of your
React Native uses a
stylesheet similar to CSS to
style components. Styles
can be added inline, or
defined in a separate file for
modularity. Styling can also
be controlled by conditional
logic and animations for
more dynamic and
React Native uses a flexbox
layout to align and position
components on the screen.
This provides a responsive
and flexible layout that can
adapt to different screen
sizes and resolutions.
6. Using Redux for State
What is Redux?
Redux is a library for managing the state of
complex applications in a predictable and
easy-to-understand way. It provides a central
store for all application data, which can be
updated using a set of standard actions and
Why use Redux?
Redux can simplify application development by
providing a structured way to manage complex
state data. It also provides powerful debugging
and monitoring tools, allowing developers to
easily identify and resolve issues.
How to implement Redux
Redux is implemented in a simple three-step
process: define the store, define the actions,
and define the reducers. Once implemented,
the store can be accessed across the entire
application, providing a centralized location for
7. Debugging React Native Apps
React Native provides a range of
debugging tools like Chrome
DevTools, React DevTools and
more. These tools allow
developers to inspect and modify
the state and props of
components, as well as monitor
performance and debug issues
Logging and Tracing
Logging and tracing can be
extremely helpful in tracking
down issues with React Native
apps. The console.log function
can be used in conjunction with
third-party tools like Crashlytics or
Sentry to provide detailed
Redux debugging tools like
Redux DevTools and Reactotron
allow developers to easily monitor
and modify the state of their
Redux store. This can be helpful
in identifying issues with state
management and debugging
complex data flows.
8. Deployment of React Native App
on iOS and Android Platforms
Deploying a React Native app on iOS requires an
Apple developer account, Xcode, and a
provisioning profile. Once these are in place, the
app can be built and uploaded to the App Store
using the Xcode application uploader.
Deploying a React Native app on Android requires
an Android developer account and Android
Studio. Once these are in place, the app can be
built and uploaded to the Google Play Store, or
distributed as an APK file.
