Prisma Adapter - NextAuth.js

Open Source. Full Stack. Own Your Data.

Overview

This is the Prisma 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 can find the Prisma schema in the docs at next-auth.js.org/adapters/prisma.

Getting Started

1. Install next-auth and @next-auth/prisma-adapter@canary

npm install next-auth @next-auth/prisma-adapter@canary

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

import NextAuth from "next-auth"
import Providers from "next-auth/providers"
import { PrismaAdapter } from "@next-auth/prisma-adapter"
import * as Prisma from "@prisma/client"

const prisma = new Prisma.PrismaClient()

// For more information on each option (and a full list of options) go to
// https://next-auth.js.org/configuration/options
export default NextAuth({
  // https://next-auth.js.org/configuration/providers
  providers: [
    Providers.Google({
      clientId: process.env.GOOGLE_ID,
      clientSecret: process.env.GOOGLE_SECRET,
    }),
  ],
  adapter: PrismaAdapter(prisma)
  ...
})

Custom Fields

In order to add custom fields to the database, you must first add them to your Prisma schema file, for example.

model User {
  id            String    @id @default(cuid())
  name          String?
  email         String?   @unique
  emailVerified DateTime?
  image         String?
> google        String?
  createdAt     DateTime  @default(now())
  updatedAt     DateTime  @updatedAt
  accounts      Account[]
  sessions      Session[]
}

When running prisma migrate, Prisma will create the User table with the above schema in your specified underlying database.

Then, during the first sign-in NextAuth.js will return the simpler prototype user object, but after the first sign-in, NextAuth.js will return the full custom User object, including your custom field and userId, in callbacks such as signIn.
