Open Source. Full Stack. Own Your Data.

Bundle Size @next-auth/upstash-adapter Version

Overview

This is the Upstash Redis adapter for next-auth. This package can only be used in conjunction with the primary next-auth and @upstash/redis packages. It is not a standalone package.

Getting Started

Install next-auth and @next-auth/upstash-redis-adapter as well as @upstash/redis via NPM.

npm install next-auth @next-auth/upstash-redis-adapter @upstash/redis

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

import NextAuth from "next-auth"
import { UpstashRedisAdapter } from "@next-auth/upstash-adapter"
import upstashRedisClient from "@upstash/redis"

const redis = upstashRedisClient("UPSTASH_REDIS_REST_URL", "UPSTASH_REDIS_REST_TOKEN")

// 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: UpstashRedisAdapter(redis)
  ...
})

Using Multiple Apps with a Single Upstash Redis Instance

The Upstash free-tier allows for only one 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: UpstashRedisAdapter(redis, {baseKeyPrefix: "app2:"})
  ...
})
