Expo + Next.js Monorepo Example

Here is an example showing how to create a universal React app using Expo and Next.js in a monorepo.

You’ll find included:

  • Expo SDK 43 (with Hermes on iOS and Android)
  • Next.js 12
  • React Native for Web
  • TypeScript
  • Babel config that works for Expo and Next.js with Reanimated in a monorepo
  • Reanimated
  • React Native Bottom Sheet
  • Dripsy

And ready-to-use (small configuration required):

  • Expo Application Services
  • Custom Development Client
  • Sentry

Architecture

App

Code shared between iOS, Android and Web

cd packages/app

Expo

Native

Expo entrypoint: packages/expo/App.tsx

cd packages/expo

yarn start:expo to start iOS and Android app with Expo

Demo: https://expo.dev/@poolpoolpool/example?release-channel=production

Pro tip: build and launch a custom development client with SCHEME=com.example.axel yarn run:ios -d (replace axel with your first name)

Next.js

Web

Next.js entrypoint: packages/next/src/pages/_app.tsx

cd packages/next

yarn dev to start web app

Demo: https://expo-next-monorepo-example.vercel.app

Notes

Root

  • Don’t add any package here

App

  • Don’t add any package here

Expo

  • Add all your React Native and universal packages here
  • Publish to Expo with yarn publish:production

Next.js

  • Add your web-only packages here
  • Deploy to Vercel with yarn deploy — if it fails, make sure to configure your project correctly:
    go to your project settings on Vercel and set the “Framework Preset” to Next.js and the “Root Directory” to packages/next

Navigation

Here is an example of how to handle navigation: https://github.com/axeldelafosse/expo-next-monorepo-example/pull/1

What should I do next?

Here are some ideas to get you started:

  • Use React Navigation
  • Style your app with Dripsy
  • Animate your app with Moti
  • Do some requests with SWR or Apollo Client
  • Build cool things with Expo Modules
  • Create a custom development client
  • Add Sentry
  • Add CI/CD with EAS via GitHub Actions
  • …
