Expo + Next.js + Storybook (using React Native for Web) 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
• Storybook using React Native for Web

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 apps/expo

yarn dev 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 apps/next

yarn dev to start web app

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

Storybook React

Storybook for Web (using React Native for Web)

Storybook config: apps/storybook/.storybook/*

cd apps/storybook

yarn storybook to start Storybook

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
• ...
