This is a fork of the original upstash-redis

Overview

This is a Redis (ioredis) adapter for next-auth.

Getting Started

1. Install next-auth and adapter-redis (TODO, just copy the file directly into your project for now) as well as ioredis via NPM.

npm install next-auth ioredis adapter-redis

2. Add the follwing code to your pages/api/[...nextauth].js next-auth configuration object.

import NextAuth from "next-auth"
import { RedisAdapter } from "adapter-redis"
import Redis from "ioredis"

const client = new Redis(process.env.REDIS_URL)

// For more information on each option (and a full list of options) go to
// https://next-auth.js.org/configuration/options
export default NextAuth({
  ...
  adapter: RedisAdapter(client)
  ...
})

Using Multiple Apps with a Single Redis Instance

If you have multiple Next-Auth connected apps using this instance, you need different key prefixes for every app.

You can change the prefixes by passing an options object as the second argument to the adapter factory function.

The default values for this object are:

const defaultOptions = {
  baseKeyPrefix: "",
  accountKeyPrefix: "user:account:",
  accountByUserIdPrefix: "user:account:by-user-id:",
  emailKeyPrefix: "user:email:",
  sessionKeyPrefix: "user:session:",
  sessionByUserIdKeyPrefix: "user:session:by-user-id:",
  userKeyPrefix: "user:",
  verificationTokenKeyPrefix: "user:token:",
};

Usually changing the baseKeyPrefix should be enough for this scenario, but for more custom setups, you can also change the prefixes of every single key.

Example:

export default NextAuth({
  ...
  adapter: RedisAdapter(redis, {baseKeyPrefix: "app2:"})
  ...
})

Testing

A docker-compose file is provided to run a redis instance for testing purposes.

docker-compose up
npm run test
