Turbo-t3-expo

This is an example monorepo for create-t3-app and expo. If you want to create your own from scratch, make sure all of your react, react-dom, @types/react, and @types/react-dom are at the same version as the expo app in other apps.

What's inside?

This turborepo uses Yarn as a package manager. It includes the following packages/apps:

Apps and Packages

• docs: a Next.js app
• web: a create-t3-app app
• api: a shared library for all apps. Includes a prisma client, a trpc router, next-auth options, and expo-auth functionalities
• ui-web: a stub React component library shared by both web and docs applications
• eslint-config-custom: eslint configurations (includes eslint-config-next and eslint-config-prettier)
• tsconfig: tsconfig.jsons used throughout the monorepo
• prisma: a schema.prisma file with optional db.sqlite

Next-auth with Expo

This example app uses a lot of logic from Next-auth to implement the same/similar features for mobile. To make this possible, no cookies are used for authentication. Here's how it works:

1. From the Expo app, a request is made and the response is verified.
2. The Expo verfied response, is sent to a tRCP endpoint and verfied once again by the .expo-auth router.
3. Once successful, a JWT token is generated, the user and account is updated accordingly, and the new JWT and user is sent to the Expo app.

Remote Caching

Turborepo can use a technique known as Remote Caching to share cache artifacts across machines, enabling you to share build caches with your team and CI/CD pipelines.

By default, Turborepo will cache locally. To enable Remote Caching you will need an account with Vercel. If you don't have an account you can create one, then enter the following commands:

cd my-turborepo
npx turbo login

This will authenticate the Turborepo CLI with your Vercel account.

Next, you can link your Turborepo to your Remote Cache by running the following command from the root of your turborepo:

npx turbo link
