Hello World, Welcome to projectsplaza.com. Today I am going to create a hello world app with react native. I will create this react native app with expo. This is a very simple application. Our main goal of this tutorial is to install react native on the window system and create our first application. I have defined the following steps to create a hello world app with react native.

• Install NodeJs
• Install expo mobile app from play store
• Install expo with this command “npm i -g expo-cli”
• Install react native with this command “expo init app-name”. It will ask you about app type template. You will just create a blank template.
• Go to app folder with this command “cd app-name”
• Now run the app “npm start” command.
• You will see the bar code.
• Open your expo mobile app and scan the bar code.
• Now the app is running on your screen.
