Discussion on: Tutorial: How to share code between iOS, Android & Web using React Native, react-native-web and monorepo

View post

Hello Bruno,

1.) Now that Expo for Web was released, what would you recommend?
To setup a monorepo for Mobile and Web packages or to use Expo for Web?
There's also a React Native Web CLI called create-react-native-web-app.

2.) And also could you give some guide how to setup Next.js as a package of this monorepo? Upon running yarn create next-app --example with-react-native-web next, here's the response:

Thanks for any response!

Expo has it's own set of limitations, e.g. I've been using hooks in production since november 2018 and it only arrived in expo may 2019. If you are ok using expo go for it! They seem to be doing great progress.

About next, I don't know what the issue is, try creating the project separately and copy pasting the folder into the monorepo. Otherwise open an issue with them about monorepo support.
