How does NextAuth persist session cookie in t3 stack
In an app created with create-t3-app, NextAuth is set up without the use of Next middlewares.
From my experience using Next with App Dir, a cookie can only be set server-side in a middleware or in a route handler. As said earlier, there are no NextAuth middlewares in created project, nor does NextAuth use a route handler to persist a session (eg. refresh session token).
The only NextAuth entrypoint in project is
getServerAuthSession call in createTRPCContext.
Furthermore, tRPC is setup to use unstable_httpBatchStreamLink which streams the response (same streaming RSC), so you can't set a cookie with tRPC.
After thinking a bit,
probably, createTRPCContext is run prior to sending the initial response. This is the only way I could imagine this works.
https://trpc.io/docs/server/context suggests that createTRPCContext is run "for each invocation of tRPC". However, that does not suggest that it is run prior to sending the initial response.
Am I right? What am I missing here? Where can I find relevant documentation?3 replies
