React-Native is a game changer when it comes to mobile-apps Development. You can use React-Native for modifying your existing android/ios or you can create a whole new app from scratch.
In this article I will teach you to set your developer environment with visual studio code which allows you to get started with react-native quickly. So, let's get started by following all the given steps.
STEP 1: Go to your command prompt
Open up your command terminal by simply searching for "command prompt" in your search bar. First of all you have to install the latest version for node(https://nodejs.org/en/).If you have already installed, you can check that up by typing "node -v" in your command promt.
After you successfully confirmed your node installed, you can now further type in "npm i -g expo-cli"
This will install the expo command line interface(CLI) which hides alot of complexity while building the native apps.
STEP 2: Open up Visual Studio Code
Go to the terminal of vs code and type in "expo init your-project-name"
STEP 3: Install NPM modules
Initialize package manager by typing in "npm init" and after that install the modules for npm by typing "npm install" and at last start your application with "npm start"
Now, everything is set-up and you can play around with react-native pretty much in no time.You can download android emulator
(https://developer.android.com/studio) and run your application on it.This is it :)
Thank you so much.
