Turborepo: Supabase Social Authentication with Expo Router

A blog post that explains the process of creating Google/Apple logins with Supabase, accompanies this repository. With this repository, I wanted to give an example and guidance on how to use Supabase Social Authentication together with Expo Router v2. Both Google Authentication as well as Apple Authentication are covered. This repository is built as a monorepo using Turborepo and PNpm.

How to use

git clone git@github.com:rnnyrk/social-auth-monorepo.git YOUR_PROJECT
cd YOUR_PROJECT
pnpm i

For local development you should also run pnpm build, to build the local /packages folder. And run pnmp dev after to build the Expo app. If the bundling isn't working directly, first prebuild your application:

cd apps/native
pnpm prebuild

The pnpm dev command is configured to bundle an iOS app. If you rather develop by default for Android, change the NPM dev script in apps/native/package.json to pnpm android.

Within the apps/native directory, you can find the Expo app. Over there, create an environment file on .env.development and fill in the required properties:

EXPO_PUBLIC_SUPABASE_URL_DEV=
EXPO_PUBLIC_SUPABASE_PUBLIC_KEY_DEV=
EAS_PROJECT_ID=

Create a build for a simulator

iOS eas build --profile simulator --platform ios
Android eas build --profile development --platform android

OR Create a build for a device

iOS eas device:create && eas build --profile development --platform ios
Android eas build --profile development --platform android

Submit the build:

iOS APP_ENV=staging eas submit -p ios --profile staging
