NextAuth.js Setup

Configure authentication with multiple providers

// app/api/auth/[...nextauth]/route.ts
import NextAuth from "next-auth"
import GoogleProvider from "next-auth/providers/google"
import { DrizzleAdapter } from "@auth/drizzle-adapter"
import { db } from "@/lib/db"

export const authOptions = {
  adapter: DrizzleAdapter(db),
  providers: [
    GoogleProvider({
      clientId: process.env.GOOGLE_CLIENT_ID!,
      clientSecret: process.env.GOOGLE_CLIENT_SECRET!,
    }),
  ],
  callbacks: {
    session: async ({ session, user }) => {
      session.user.id = user.id
      return session
    },
  },
}

const handler = NextAuth(authOptions)
export { handler as GET, handler as POST }

Protected Route Example

Server-side authentication check

// app/dashboard/page.tsx
import { getServerSession } from "next-auth"
import { redirect } from "next/navigation"
import { authOptions } from "@/app/api/auth/[...nextauth]/route"

export default async function DashboardPage() {
  const session = await getServerSession(authOptions)
  
  if (!session) {
    redirect("/api/auth/signin")
  }

  return (
    <div>
      <h1>Welcome, {session.user.name}!</h1>
    </div>
  )
}
