Go backend

Hi all, I'm currently working on setting up authentication for both a web frontend (using TanStack Start) and a mobile app (Expo, though I haven't started on the mobile side yet). The project is set up as a Turborepo with shared TypeScript code, so ideally I can reuse the same auth instance across both platforms. However, I'm using Go for the backend for various reasons, and I’ve run into two main issues: Handling cookies in the Go middleware. I assume there’s a way to do this via the better-auth docs or possibly through a utility/helper package, but I haven’t found a clear example yet. Connecting the Go backend to the handler used here: https://www.better-auth.com/docs/integrations/tanstack#mount-the-handler Is there a way to wire this up with my Go backend? Or is that handler expected to run in a TypeScript environment only? Additionally, I’m could use Drizzle just for the auth-related database operations if it simplifies integration (personally sounds a bit weird). But I’m unsure how I’d then handle auth on the Expo mobile app — any advice on that would also be appreciated.

I’ve been thinking of a possible solution, but I’m not sure if it’s a good approach or not. Instead of using cookies, I’m considering using JWTs for authentication. Since I already have the token and a backend package handling JWTs, this should work fine. The main concern is around the api/auth route, especially in the context of integrating with TanStack Start and Expo, as described here: https://www.better-auth.com/docs/integrations/tanstack#mount-the-handler. One idea is to use Drizzle for managing the user auth tables and reuse the same api/auth endpoint for both the TanStack Start and Expo projects. so it can perform the same CRUD operations
