NextAuth.js with hygraph

The popular React framework that has dominated developers node_modules folders over the last few years we all know of is Next.js — and rightly so, with its stellar developer experience, blazing fast compiler, and tons more.

One topic that often comes up in discussions when evaluating if Next.js is right for you is whether or not it can handle authentication. For a long time there wasn't any "documentation" around this, which led to many developers building and pitching their own solutions to handle Next.js Auth.

Let me introduce to you NextAuth.js — Authentication for Next.js. It's completely open source, and you are in control of your data. It boasts itself on being secure, flexible, and easy to use.

Note: You'll need a Hygraph account, and Next.js application if you're following along. You'll also need your Hygraph endpoint, and a Permanent Auth Token with permissions to query and mutate the NextUser model.

#1. Configure Hygraph

I'll make the assumption you already have a Hygraph account, and project. If not, you know what to do.

We'll opt to store user data from NextAuth.js, including user email and encrypted passwords.

To keep things simple for the purposes of this tutorial, create the model NextUser with two fields:

  • Email / Single line text / Required / Unique
  • Password / Single line text / Required / API Only

NextUser Model Schema

Make sure you set the Password field to API only within the advanced visibility settings.

#2. Setup dependencies

We'll be using the following dependencies to configure, and work with NextAuth.js:

  • next-auth
  • bcrypt
  • graphql-request
  • graphql
npm install next-auth@beta bcrypt graphql-request graphql

Next, create the file .env and add your Hygraph endpoint and token:


#3. Configure NextAuth.js

Within your Next.js project, add the file [...nextauth].js in pages/api/auth and invoke the CredentialsProvider.

import NextAuth from "next-auth";
import CredentialsProvider from "next-auth/providers/credentials";
export default NextAuth({
providers: [
name: "Email and Password",
credentials: {
email: {
label: "Email",
type: "email",
placeholder: ""
password: {
label: "Password",
type: "password",
placeholder: "Password"

Now, this code alone won't do anything other than give you an email and password form at the route /api/auth/signin.

NextAuth Credentials Form

Next you'll want to create (or update if it exists) pages/_app.[js,ts] to wrap your application with `SessionProvider, passing it the session from the component props:

import { SessionProvider } from 'next-auth/react';
export default function MyApp({
pageProps: { session, ...pageProps },
}) {
return (
<SessionProvider session={session}>
<Component {...pageProps} />

#4. Integrate Hygraph

We'll be working within pages/api/auth/[...nextauth].js to handle checking Hygraph if a user exists, and if they don't, create one.

Add the following imports:

import { compare, hash } from "bcrypt";
import { GraphQLClient } from "graphql-request";

Let's now create a GraphQL client for Hygraph with our endpoint and Permanent Auth Token.

const client = new GraphQLClient(process.env.HYGRAPH_ENDPOINT, {
headers: {
Authorization: `Bearer ${process.env.HYGRAPH_TOKEN}`,

Now, we'll add a query to get a user by email and a mutation to create a user with an email and password:

const GetUserByEmail = gql`
query GetUserByEmail($email: String!) {
user: nextUser(where: { email: $email }, stage: DRAFT) {
const CreateNextUserByEmail = gql`
mutation CreateNextUserByEmail($email: String!, $password: String!) {
newUser: createNextUser(data: { email: $email, password: $password }) {

Don't worry, we won't be saving passwords as plain text, but instead using the bcrypt library we installed to hash, and verify.

Inside of the CredentialsProvider config below credentials, add the following authorize function:

authorize: async ({ email, password }) => {
const { user } = await client.request(GetUserByEmail, {
if (!user) {
const { newUser } = await client.request(
password: await hash(password, 12),
return {
username: email,
const isValid = await compare(password, user.password);
if (!isValid) {
throw new Error("Wrong credentials. Try again.");
return {
username: email,

#5. Current user UI

Now, let's finish by updating creating an pages/index.js to show our current user state and links to sign in/out based on our session state.

import { useSession, signIn, signOut } from "next-auth/react";
function AuthLinks() {
const { data: session, status } = useSession();
const loading = status === "loading";
if (loading) return null;
return (
{session ? (
<span>Signed in as {session?.user?.email}</span>
<button onClick={signOut}>Sign out</button>
) : (
<button onClick={signIn}>Sign in</button>
export default function IndexPage() {
return <AuthLinks />;

#6. Demo

You should by now have something that looks like this:

There you have it! You've now used NextAuth.js and Hygraph to authenticate your Next.js users.
