We are setting up a React-Native Environment In the Windows system.

Introduction:

What is React-Native:

React-Native is a JavaScript framework that is used to build cross-platform mobile applications.

Prerequisite:

JavaScript
React Core Concepts Understanding

Installation Steps:

NodeJS click here to download
Java JDK higher version click here to download (I have chosen OpenJDK to download Java you can choose Oracle official page to download Java)
Android Studio for running JDK configuration files click here to download
Then you need to configure all the environment variables in your system.

After this, you have to install the NodeJs Chocolatey, package manager.

 Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))

The reason for installing Chocolatey is that React requires Java SE Development Kit (JDK) which can be installed using Chocolatey
Open the command and run it as administration and then run the following command
```
 choco install -y nodejs-lts microsoft-openjdk17
```
After Everything is set up create a react-native project by running the following command
```
 npx react-native init appname
```
If you encounter the following error then add npm folder inside the following directory C:\Users\username\AppData\Roaming and run the step 8 command again.
Then open the project into vs code
```
cd appname
code .
```
After successfully creating your project, the structure will look like this.
Now run the following commands to execute the application

Important things to note:

💡

if you want to run your application on a virtual emulator then you have to open the Android Studio click on more Actions then select the virtual device manager option there you can select the virtual emulator.

💡

To run your application on a physical mobile device, enable USB debugging in your device settings under the Developer options. Connect your device to your PC via USB, ensure it's recognized in Android Studio, and then select it as the target device when running your app. This allows for direct testing and debugging on your mobile for real-time development feedback.

To install all the node dependencies:

npm i

To run the application on Android

npx react-native run-android

To run the application on IOS

npx react-native run-ios

After executing the command above, depending on whether you prefer iOS or Android, the execution process will begin. Please note that the duration may vary depending on your PC's performance.
After successful build completion, the application will execute

Finally, The First App Looks something like this
