Where could I find v4 adapters documentation?

[pschaub]

I would like to use the current stable version of next-auth (v4.22.1) with the current stable version of the prisma adapter. I am using Next.js v13.4 with app router.

I followed the documentation for route handlers: https://next-auth.js.org/configuration/initialization#route-handlers-app

Then I tried to add the prisma adapter by reading the documentation: https://next-auth.js.org/adapters
There the documentation is linking to the new @auth/prisma-adapter in the Auth.js documentation: https://authjs.dev/reference/adapter/prisma

I tried to use the new @auth/prisma-adapter with next-auth v4.22.1 but this does not work. I tried this code:

import NextAuth from "next-auth";
import { PrismaAdapter } from "@auth/prisma-adapter";
import { PrismaClient } from "@prisma/client";

const prisma = new PrismaClient();

const handler = NextAuth({
    adapter: PrismaAdapter(prisma),
    // ...
})

export { handler as GET, handler as POST }

The IDE shows this error on the adapter key:

TS2322: Type 'Adapter' is not assignable to type 'Adapter | undefined'.

Then I understood that the new @auth/* adapters are not compatible with the current stable version of next-auth (v4.22.1).
The solution is to use the v4 compatible adapters @next-auth/prisma-adapter instead.

Where could I find the documentation for v4 adapters? Have they been fully removed?

Use import { PrismaAdapter } from "@next-auth/prisma-adapter" instead of import { PrismaAdapter } from "@auth/prisma-adapter". @auth/prisma-adapter is for version 5.

I found documentation in the Internet Archive - v4 Database Adapters
