This is a new just a fun project. My imagination of how Instagram app’d look on Apples’ new VisionOS.
Note: Make sure you have completed the React Native – Environment Setup instructions till “Creating a new application” step, before proceeding.
Step 1: Start the Metro Server
To start Metro, run the following command from the root of your React Native project:
# using npm npm start # OR using Yarn yarn start
Step 2: Start your Application
Let Metro Bundler run in its own terminal. Open a new terminal from the root of your React Native project. Run the following command to start your Android or iOS app:
# using npm npm run android # OR using Yarn yarn android
# using npm npm run ios # OR using Yarn yarn ios
If everything is set up correctly, you should see your new app running in your Android Emulator or iOS Simulator shortly provided you have set up your emulator/simulator correctly.
This is one way to run your app — you can also run it directly from within Android Studio and Xcode respectively.
Step 3: Modifying your App
Now that you have successfully run the app, let’s modify it.
App.tsxin your text editor of choice and edit some lines.
For Android: Press the
Rkey twice or select “Reload” from the Developer Menu (
M(on Window and Linux) or
M(on macOS)) to see your changes!
For iOS: Hit
Rin your iOS Simulator to reload the app and see your changes!
