This project has been converted to a Turborepo monorepo containing both a Next.js web application and an Expo 54 mobile application with shared packages.

This monorepo includes the following packages and apps:

• apps/web: Next.js 15 web application

  • Full-stack SaaS starter kit with authentication (NextAuth.js)
  • Database integration with Prisma (PostgreSQL)
  • Stripe payment integration
  • MDX blog support
  • Styled with Tailwind CSS
  • Runs on port 5000 for Replit compatibility

• apps/mobile: Expo 54 mobile application

  • Built with Expo Router for file-based navigation
  • React Native 0.81
  • React 19 support
  • TypeScript enabled
  • Cross-platform (iOS, Android, Web)

• packages/typescript-config: Shared TypeScript configurations

  • base.json: Base TypeScript config
  • nextjs.json: Next.js specific config
  • react-native.json: React Native/Expo config

• packages/eslint-config: Shared ESLint configurations

  • next.js: ESLint config for Next.js
  • react-native.js: ESLint config for React Native

From the root directory:

npm install --legacy-peer-deps

Note: The --legacy-peer-deps flag is required due to React 19 compatibility.

cd apps/web && npm run dev

The web app will be available at http://localhost:5000

cd apps/mobile && npm run dev

Then:

1. Install the Expo Go app on your mobile device
2. Scan the QR code displayed in the terminal
3. Your app will open in Expo Go

npm run dev

This runs all development servers concurrently.
