DynamoDB Adapter - NextAuth.js

Open Source. Full Stack. Own Your Data.

Overview

This is the AWS DynamoDB Adapter for next-auth. This package can only be used in conjunction with the primary next-auth package. It is not a standalone package.

You need a table with a partition key pk and a sort key sk. Your table also needs a global secondary index named GSI1 with GSI1PK as partition key and GSI1SK as sorting key. You can set whatever you want as the table name and the billing method.

You can find the full schema in the table structure section below.

Getting Started

1. Install next-auth and @next-auth/dynamodb-adapter

npm install next-auth @next-auth/dynamodb-adapter

1. Add this adapter to your pages/api/[...nextauth].js next-auth configuration object.

You need to pass aws-sdk to the adapter in addition to the table name.

import AWS from "aws-sdk";
import NextAuth from "next-auth";
import Providers from "next-auth/providers";
import { DynamoDBAdapter } from "@next-auth/dynamodb-adapter"

AWS.config.update({
  accessKeyId: process.env.NEXT_AUTH_AWS_ACCESS_KEY,
  secretAccessKey: process.env.NEXT_AUTH_AWS_SECRET_KEY,
  region: process.env.NEXT_AUTH_AWS_REGION,
});

export default NextAuth({
  // Configure one or more authentication providers
  providers: [
    Providers.GitHub({
      clientId: process.env.GITHUB_ID,
      clientSecret: process.env.GITHUB_SECRET,
    }),
    Providers.Email({
      server: process.env.EMAIL_SERVER,
      from: process.env.EMAIL_FROM,
    }),
    // ...add more providers here
  ],
  adapter: DynamoDBAdapter({
    AWS,
    tableName: "next-auth-test",
  }),
  ...
});

(AWS secrets start with NEXT_AUTH_ in order to not conflict with Vercel's reserved environment variables.)

Table structure

The table respects the single table design pattern. This has many advantages:

• Only one table to manage, monitor and provision.
• Querying relations is faster than with multi-table schemas (for eg. retreiving all sessions for a user).
• Only one table needs to be replicated, if you want to go multi-region.

Here is a schema of the table :
