🗂 Project organization

This project was bootstrapped with npm create tamagui

The main apps are:

• expo (native)

• next (web)

• packages shared packages across apps

  • ui includes your custom UI kit that will be optimized by Tamagui
  • 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.)

🏁 Start the app

• Install dependencies: yarn

• Next.js local dev: yarn web

To run with optimizer on in dev mode (just for testing, it's faster to leave it off): yarn web:extract. To build for production yarn web:prod.

To see debug output to verify the compiler, add // debug as a comment to the top of any file.

• Expo local dev: yarn native

🆕 Adding 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 expo:

cd apps/expo
yarn add react-native-reanimated
cd ..
yarn

Updating dependencies

Pure JS dependencies

yarn upgrade-interactive

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).

You may potentially want to have the native module transpiled for the next app. If you get error messages with Cannot use import statement outside a module, you may need to use transpilePackages in your next.config.js and add the module to the array there.
