Expo

Vercel

https://skyhitz-expo-next.vercel.app/

📦 Included packages

• solito for cross-platform navigation
• dripsy for theming/design (you can bring your own, too)
• Expo SDK 44
• Next.js 12
• React Navigation 6

🗂 Folder layout

• apps entry points for each app

  • expo
  • next

• packages shared packages across apps

  • app you'll be importing most files from app/
    • features (don't use a screens folder. organize by feature.)
    • provider (all the providers that wrap the app, and some no-ops for Web.)
    • navigation Next.js has a pages/ folder. React Native doesn't. This folder contains navigation-related code for RN. You may use it for any navigation code, such as custom links.

You can add other folders inside of packages/ if you know what you're doing and have a good reason to.

🏁 Start the app

• Install dependencies: yarn

• Next.js local dev: yarn web

  • Runs yarn next

• Expo local dev: yarn native

  • Runs expo start

🆕 Add new dependencies

Pure JS dependencies

If you're installing a JavaScript-only dependency that will be used across platforms, install it in packages/app:

cd packages/app
yarn add date-fns
cd ../..
yarn

Native dependencies

If you're installing a library with any native code, you must install it in apps/expo:

cd apps/expo
yarn add react-native-reanimated

cd ../..
yarn

You can also install the native library inside of packages/app if you want to get autoimport for that package inside of the app folder. However, you need to be careful and install the exact same version in both packages. If the versions mismatch at all, you'll potentially get terrible bugs. This is a classic monorepo issue. I use lerna-update-wizard to help with this (you don't need to use Lerna to use that lib).

Graphql

To add graphql query/mutation simply create file in the proper folder:

• packages/app/api/queries/your_query.graphql for queries
• packages/app/api/mutations/your_mutation.graphql for mutations

Then run the following script and let codegen generate graphql types for you:

yarn graphql:gen
