MongoDB Adapter - NextAuth.js

Open Source. Full Stack. Own Your Data.

Overview

This is the MongoDB Adapter for auth.js. This package can only be used in conjunction with the primary auth.js package. It is not a standalone package.

Getting Started

1. Install mongodb, next-auth and @next-auth/mongodb-adapter

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

2. Add lib/mongodb.js

// This approach is taken from https://github.com/vercel/next.js/tree/canary/examples/with-mongodb
import { MongoClient } from "mongodb"

const uri = process.env.MONGODB_URI
const options = {
  useUnifiedTopology: true,
  useNewUrlParser: true,
}

let client
let clientPromise

if (!process.env.MONGODB_URI) {
  throw new Error("Please add your Mongo URI to .env.local")
}

if (process.env.NODE_ENV === "development") {
  // In development mode, use a global variable so that the value
  // is preserved across module reloads caused by HMR (Hot Module Replacement).
  if (!global._mongoClientPromise) {
    client = new MongoClient(uri, options)
    global._mongoClientPromise = client.connect()
  }
  clientPromise = global._mongoClientPromise
} else {
  // In production mode, it's best to not use a global variable.
  client = new MongoClient(uri, options)
  clientPromise = client.connect()
}

// Export a module-scoped MongoClient promise. By doing this in a
// separate module, the client can be shared across functions.
export default clientPromise

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

import NextAuth from "next-auth"
import { MongoDBAdapter } from "@next-auth/mongodb-adapter"
import clientPromise from "lib/mongodb"

// For more information on each option (and a full list of options) go to
// https://authjs.dev/reference/configuration/auth-options
export default NextAuth({
  adapter: MongoDBAdapter(clientPromise, {
    databaseName: 'my-data-base-name'
  }),
  ...
})
