import PostgresAdapter from "@auth/pg-adapter"
import { Pool } from "pg"
const pool = new Pool({
host: process.env.DATABASE_HOST,
user: process.env.DATABASE_USER,
password: process.env.DATABASE_PASSWORD,
database: process.env.DATABASE_NAME,

idleTimeoutMillis: 30000,
connectionTimeoutMillis: 2000,
})
export const { handlers, auth, signIn, signOut } = NextAuth({
adapter: PostgresAdapter(pool),
providers: [],
})If you are using Neon’s PostgreSQL like Vercel Postgres, you can use @neondatabase/serverless to work with edge runtime.
./auth.ts
import NextAuth from "next-auth"
import PostgresAdapter from "@auth/pg-adapter"
import { Pool } from "@neondatabase/serverless"
// *DO NOT* create a `Pool` here, outside the request handler.
// Neon's Postgres cannot keep a pool alive between requests.
export const { handlers, auth, signIn, signOut } = NextAuth(() => {
// Create a `Pool` inside the request handler.
const pool = new Pool({ connectionString: process.env.DATABASE_URL })
return {
adapter: PostgresAdapter(pool),
providers: [],
}
})Schema
