A proposal to use Better Auth instead of Next Auth as a the auth provider

[Bekacru]

Describe the feature you'd like to request

The current implementation of Auth requires a lot of workarounds in the user land to make NextAuth work for both Expo and nextjs, as well as to enable preview deployments.

Describe the solution you'd like to see

Better Auth is a new authentication library with a plugin ecosystem, allowing for easier integration of features like these. It includes Expo integration that works out of the box and supports OAuth logins for preview deployments without needing a proxy server.

Additional information

Perhaps before this is considered, Better Auth should be an optional authentication provider in the Create T3 App. I already have a fork that implements Better Auth for Create T3 Turbo, which you can take a look at.

Hey @Bekacru,

When I tried

npx create-turbo@latest -e https://github.com/Bekacru/create-t3-turbo

I did get the error:

│ > pnpm dlx sherif@latest
│ 1 issue found in ./:
│  ⨯ error Dependency @better-auth/expo has multiple versions defined in the workspace. multiple-dependency-versions
│   ./apps
│       expo                      ^1.1.15-beta.7   ↑ highest

and had to manually change ./packages/auth/package.json to ^1.1.15-beta.7 before reinstalling.

Would you be able to fix this, as well as consider:

• enabling issues & discussions in the fork
• syncing the latest commits from upstream

Thank you!

still having issues even after fixing this! unfortunately

@Hidde-Heijnen yeah, there's probably a few other dependencies that you will need to align for it to work.

I made a turborepo for a different stack (tanstack router + hono instead of nextjs), but I was able to integrate it successfully with Better-Auth - you can copy the relevant parts from here or use it as reference if you need:
