Expo Starter Kit with React Viro (TypeScript)

React Viro AR/VR starter kit for Expo with TypeScript.

Prerequisites

• React Viro requires native code and cannot run in Expo Go
• You must use development builds or prebuild to run this project

Installation

npm install

Setup

Generate native directories (required for ViroReact):

npx expo prebuild --clean

Check for any project issues:

npx expo-doctor

Running

Development builds (recommended):

npx expo run:ios
npx expo run:android

Development server (after building):

npx expo start --dev-client

Troubleshooting

iOS Build Error: "no such module 'ExpoModulesCore'"

If building through npx expo run:ios presents the following error "no such module 'ExpoModulesCore'", follow these steps:

1. Start your development server:

   npx expo start --dev-client

2. Open the Xcode workspace for the project within the ios folder:

   open ios/expostarterkittypescript.xcworkspace

3. Build and run the application directly within Xcode

This ensures the Metro bundler is running and properly connected to your iOS build.
