Required dependencies

Install only what your chosen adapter requires:

# Core (always required)
npm install @auth/core

# Drizzle ORM adapter
npm install drizzle-orm @auth/drizzle-adapter
npm install drizzle-kit --save-dev

# Prisma adapter
npm install @prisma/client @auth/prisma-adapter

# DynamoDB adapter
npm install @aws-sdk/lib-dynamodb @aws-sdk/client-dynamodb @auth/dynamodb-adapter

# Azure Table Storage adapter
npm install @azure/data-tables @auth/azure-tables-adapter

# Cloudflare D1 adapter (Workers runtime — no separate npm install needed)
npm install @auth/d1-adapter

# Dgraph adapter
npm install @auth/dgraph-adapter

# MongoDB adapter
npm install mongodb @auth/mongodb-adapter

# Upstash Redis adapter
npm install @upstash/redis @auth/upstash-redis-adapter

# Next.js
npm install next-auth

No native build steps (pod install / NDK) are required. For Cloudflare D1, the @cloudflare/workers-types and @miniflare/d1 packages are type-only peer dependencies; install them as devDependencies.

Project setup

1. Copy the source/ directory into your project root, e.g. src/auth-source/.

2. In tsconfig.json add path aliases so relative workspace imports resolve:

{
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "@auth/core/*": ["src/auth-source/core/src/*"],
      "@auth/drizzle-adapter": ["src/auth-source/adapter-drizzle/src/index.ts"],
      "@auth/dynamodb-adapter": ["src/auth-source/adapter-dynamodb/src/index.ts"]
    },
    "moduleResolution": "Bundler",
    "target": "ES2022"
  }
}

3. Set required environment variables:

AUTH_SECRET=your_32_byte_random_secret
AUTH_URL=https://yourdomain.com
# Provider-specific keys, e.g.:
AUTH_GITHUB_ID=...
AUTH_GITHUB_SECRET=...

4. For the Drizzle adapter, generate and run migrations with drizzle-kit push against your target DB dialect.

5. For the D1 adapter, call the exported up() migration function once during Worker startup.

Public API

DrizzleAdapter

import { DrizzleAdapter } from "@auth/drizzle-adapter"
import type { Adapter } from "@auth/core/adapters"

function DrizzleAdapter<SqlFlavor extends SqlFlavorOptions>(
  db: SqlFlavor,
  schema?: DefaultSchema<SqlFlavor>
): Adapter

Pass a Drizzle db instance (MySQL, Postgres, or SQLite). Optionally supply a custom schema object mapping the four Auth.js tables. Throws at runtime if an unsupported DB type is passed.

DynamoDBAdapter

import { DynamoDBAdapter } from "@auth/dynamodb-adapter"
import type { DynamoDBAdapterOptions } from "@auth/dynamodb-adapter"

function DynamoDBAdapter(
  client: DynamoDBDocument,
  options?: DynamoDBAdapterOptions
): Adapter

interface DynamoDBAdapterOptions {
  tableName?: string        // default: "next-auth"
  partitionKey?: string     // default: "pk"
  sortKey?: string          // default: "sk"
  indexName?: string        // default: "GSI1"
  indexPartitionKey?: string
  indexSortKey?: string
}

Wraps @aws-sdk/lib-dynamodb's DynamoDBDocument. Override key/index names when your table schema differs from the defaults.

TableStorageAdapter

import { TableStorageAdapter } from "@auth/azure-tables-adapter"
import type { TableClient } from "@azure/data-tables"

function TableStorageAdapter(client: TableClient): Adapter

Takes an @azure/data-tables TableClient and returns a fully compliant Adapter. Use when deploying to Azure with Table Storage as your session/account backend.

DgraphAdapter

import { DgraphAdapter } from "@auth/dgraph-adapter"
import type { DgraphAdapterOptions, DgraphClientParams } from "@auth/dgraph-adapter"

function DgraphAdapter(
  client: DgraphClientParams,
  options?: DgraphAdapterOptions
): Adapter

Connects to a Dgraph GraphQL endpoint. The optional fragments field in DgraphAdapterOptions lets you extend the default entity shapes.

Working examples

Scenario - Drizzle ORM with Postgres and NextAuth.js

Configure NextAuth.js to persist sessions and accounts in a Postgres database via Drizzle.

// src/auth.ts
import NextAuth from "next-auth"
import GitHub from "next-auth/providers/github"
import { drizzle } from "drizzle-orm/node-postgres"
import { Pool } from "pg"
import { DrizzleAdapter } from "@auth/drizzle-adapter"

const pool = new Pool({ connectionString: process.env.DATABASE_URL })
const db = drizzle(pool)

export const { handlers, auth, signIn, signOut } = NextAuth({
  adapter: DrizzleAdapter(db),
  providers: [
    GitHub({
      clientId: process.env.AUTH_GITHUB_ID!,
      clientSecret: process.env.AUTH_GITHUB_SECRET!,
    }),
  ],
})

Scenario - DynamoDB adapter in a serverless API

Use the DynamoDB adapter with a single-table design on AWS Lambda.

// src/auth.config.ts
import { DynamoDBAdapter } from "@auth/dynamodb-adapter"
import { DynamoDBClient } from "@aws-sdk/client-dynamodb"
import { DynamoDBDocument } from "@aws-sdk/lib-dynamodb"
import NextAuth from "next-auth"
import Google from "next-auth/providers/google"

const client = DynamoDBDocument.from(
  new DynamoDBClient({ region: process.env.AWS_REGION }),
  { marshallOptions: { convertEmptyValues: true, removeUndefinedValues: true } }
)

export const { handlers, auth } = NextAuth({
  adapter: DynamoDBAdapter(client, {
    tableName: "my-auth-table",
    partitionKey: "PK",
    sortKey: "SK",
    indexName: "GSI1",
    indexPartitionKey: "GSI1PK",
    indexSortKey: "GSI1SK",
  }),
  providers: [Google],
})

Scenario - Azure Table Storage adapter with Express

Integrate Auth.js into an Express server backed by Azure Table Storage.

// src/server.ts
import express from "express"
import { ExpressAuth } from "@auth/express"
import { TableClient } from "@azure/data-tables"
import { TableStorageAdapter } from "@auth/azure-tables-adapter"
import GitHub from "next-auth/providers/github"

const tableClient = TableClient.fromConnectionString(
  process.env.AZURE_STORAGE_CONNECTION_STRING!,
  "nextauth"
)

const app = express()
app.set("trust proxy", true)

app.use(
  "/auth/*",
  ExpressAuth({
    providers: [GitHub],
    adapter: TableStorageAdapter(tableClient),
    secret: process.env.AUTH_SECRET,
  })
)

app.listen(3000)

Scenario - Cloudflare D1 adapter with Workers

Apply the D1 schema migration and configure the adapter inside a Cloudflare Worker.

// src/worker.ts
import { D1Adapter, up } from "@auth/d1-adapter"

export default {
  async fetch(request: Request, env: { DB: D1Database; AUTH_SECRET: string }) {
    // Run once to create tables (idempotent)
    await up(env.DB)

    // Adapter is ready for use with your Auth.js handler
    const adapter = D1Adapter(env.DB)
    // ... pass adapter to your Auth.js configuration
  },
}

File walkthrough

• core/ - Auth.js core: provider definitions, JWT helpers, session logic, and all shared TypeScript types (Adapter, AdapterUser, AdapterSession, etc.). Every adapter imports from here.
• adapter-drizzle/ - Drizzle ORM adapter; sub-files lib/pg.ts, lib/mysql.ts, lib/sqlite.ts handle dialect-specific SQL.
• adapter-dynamodb/ - DynamoDB adapter using the @aws-sdk/lib-dynamodb document client; includes Jest config for local DynamoDB testing.
• adapter-azure-tables/ - Azure Table Storage adapter; exports TableStorageAdapter, keys, and withoutKeys helper.
• adapter-d1/ - Cloudflare D1 adapter; exports D1Adapter, up migration runner, and raw SQL query constants.
• adapter-dgraph/ - Dgraph GraphQL adapter; uses internal client.ts and fragments.ts for query composition.
• adapter-prisma/ - Thin Prisma ORM wrapper; delegates all DB calls to the generated Prisma Client.
• adapter-mongodb/ - MongoDB adapter using the native mongodb driver.
• adapter-upstash-redis/ - Upstash Redis adapter for fully serverless, edge-compatible session storage.
• frameworks-express/ - ExpressAuth middleware for wiring Auth.js into Express apps.
• frameworks-sveltekit/ - SvelteKit handle hook and server helpers.
• frameworks-solid-start/ - SolidStart server handler integration.
• frameworks-qwik/ - Qwik City server loader integration.
• next-auth/ - The next-auth npm package; re-exports core with Next.js Route Handler wiring.
• utils/ - Internal shared utilities (not intended for direct import by consumers).

Common pitfalls and fixes

• AUTH_SECRET missing at runtime - Auth.js throws a generic error without it; set a 32-byte random string in every environment including CI and edge deployments.
• ESM/CJS interop with drizzle-orm - Drizzle ships ESM-only in recent versions; set "moduleResolution": "Bundler" or "Node16" in tsconfig.json and ensure your bundler handles .js extension imports.
• D1 adapter up() called on every request - The migration is idempotent but still incurs a DB round-trip; call it once during Worker initialization or a dedicated deploy step, not in the hot path.
• DynamoDB GSI not created - The adapter requires a GSI named GSI1 (or your override) with GSI1PK / GSI1SK attributes; missing this causes getSessionAndUser and getUserByAccount to fail silently with empty results.
• Azure Table Storage withoutKeys mutates the response object - The helper deletes partitionKey, rowKey, etag, timestamp, and odata.metadata in-place; do not cache the raw entity before calling it.
• Dgraph schema not deployed - The DgraphAdapter requires the schema from adapter-dgraph/src/lib/graphql/schema.gql to be applied to your Dgraph Cloud or self-hosted instance before any auth operations succeed.

Vibe-coding prompt template

I have dropped the Auth.js adapters source into `src/auth-source/` in my project.
The USAGE.md is at `src/auth-source/USAGE.md`.
The upstream package name is `user@example.com` (next-auth monorepo, packages/ root).

Please integrate Auth.js into my existing Node.js / TypeScript project step by step:

1. Read USAGE.md and the relevant adapter source under `src/auth-source/` for the
   database I am using: [REPLACE WITH: drizzle-postgres | dynamodb | d1 | prisma | etc.].
2. Install only the npm dependencies listed in USAGE.md for that adapter.
3. Create `src/auth.ts` that initialises Auth.js with my chosen adapter and at least
   one OAuth provider. Use environment variables for all secrets.
4. Wire the Auth.js request handler into my existing [Express / Next.js App Router /
   SvelteKit / other] server.
5. Add the required environment variables to `.env.example`.
6. If a migration step is needed (Drizzle, D1, Prisma), add a `scripts/migrate.ts`
   that runs it.
7. Do not invent any API that is not present in `src/auth-source/` or USAGE.md.
