Version: v4-unreleased

Upgrade Guide (v4)

NextAuth.js version 4 includes a few breaking changes from the last major version (3.x). So we're here to help you upgrade your applications as smoothly as possible. It should be possible to upgrade from any version of 3.x to the latest 4 release by following the next few migration steps.

note

Version 4 has been released to GA 🚨

We encourage users to try it out and report any and all issues they come across.

You can upgrade to the new version by running:

npm install next-auth

next-auth/jwt​

We no longer have a default export in next-auth/jwt. To comply with this, change the following:

- import jwt from "next-auth/jwt"
+ import { getToken } from "next-auth/jwt"

next-auth/react​

We've renamed the client-side import source to next-auth/react. To comply with this change, you will simply have to rename anywhere you were using next-auth/client.

For example:

- import { useSession } from "next-auth/client"
+ import { useSession } from "next-auth/react"

We've also made the following changes to the names of the exports:

  • setOptions: Not exposed anymore, use SessionProvider props
  • options: Not exposed anymore, use SessionProvider props
  • session: Renamed to getSession
  • providers: Renamed to getProviders
  • csrfToken: Renamed to getCsrfToken
  • signin: Renamed to signIn
  • signout: Renamed to signOut
  • Provider: Renamed to SessionProvider

Introduced in https://github.com/nextauthjs/next-auth/releases/tag/v4.0.0-next.12

SessionProvider​

Version 4 makes using the SessionProvider mandatory. This means that you will have to wrap any part of your application using useSession in this provider, if you were not doing so already. The SessionProvider has also undergone a few further changes:

  • Provider is renamed to SessionProvider
  • The options prop is now flattened as the props of SessionProvider.
  • keepAlive has been renamed to refetchInterval.
  • clientMaxAge has been removed in favor of refetchInterval, as they overlap in functionality, with the difference that refetchInterval will keep re-fetching the session periodically in the background.

The best practice for wrapping your app in Providers is to do so in your pages/_app.jsx file.

An example use-case with these new changes:

import { SessionProvider } from "next-auth/react"

export default function App({
  Component,
  pageProps: { session, ...pageProps },
}) {
  return (
    // `session` comes from `getServerSideProps` or `getInitialProps`.
    // Avoids flickering/session loading on first load.
    <SessionProvider session={session} refetchInterval={5 * 60}>
      <Component {...pageProps} />
    </SessionProvider>
  )
}

Introduced in https://github.com/nextauthjs/next-auth/releases/tag/v4.0.0-next.12

Providers​

Providers now need to be imported individually.

- import Provider from "next-auth/providers"
- Providers.Auth0({...})
- Providers.Google({...})
+ import Auth0Provider from "next-auth/providers/auth0"
+ import GoogleProvider from "next-auth/providers/google"
+ Auth0Provider({...})
+ GoogleProvider({...})
  1. The AzureADB2C provider has been renamed AzureAD.
  2. The Basecamp provider has been removed, see explanation here.
  3. The GitHub provider by default now will not request full write access to user profiles. If you need this scope, please add user to the scope option manually.

The following new options are available when defining your Providers in the configuration:

  1. authorization (replaces authorizationUrl, authorizationParams, scope)
  2. token replaces (accessTokenUrl, headers, params)
  3. userinfo (replaces profileUrl)
  4. issuer(replaces domain)

For more details on their usage, please see options section of the OAuth Provider documentation.

When submitting a new OAuth provider to the repository, the profile callback is expected to only return these fields from now on: id, name, email, and image. If any of these are missing values, they should be set to null.

Also worth noting is that id is expected to be returned as a string type (For example if your provider returns it as a number, you can cast it by using the .toString() method). This makes the returned profile object comply across all providers/accounts/adapters, and hopefully cause less confusion in the future.

Implemented in: #2411 Introduced in https://github.com/nextauthjs/next-auth/releases/tag/v4.0.0-next.20

useSession Hook​

The useSession hook has been updated to return an object. This allows you to test states much more cleanly with the new status option.

- const [ session, loading ] = useSession()
+ const { data: session, status } = useSession()
+ const loading = status === "loading"

Check the docs for the possible values of both session.status and session.data.

Introduced in https://github.com/nextauthjs/next-auth/releases/tag/v4.0.0-next.18

Named Parameters​

We have changed the arguments to our callbacks to the named parameters pattern. This way you don't have to use dummy _ placeholders or other tricks.

Callbacks​

The signatures for the callback methods now look like this:

- signIn(user, account, profileOrEmailOrCredentials)
+ signIn({ user, account, profile, email, credentials })
- redirect(url, baseUrl)
+ redirect({ url, baseUrl })
- session(session, tokenOrUser)
+ session({ session, token, user })
- jwt(token, user, account, OAuthProfile, isNewUser)
+ jwt({ token, user, account, profile, isNewUser })

Introduced in https://github.com/nextauthjs/next-auth/releases/tag/v4.0.0-next.17

Events​

Two event signatures have changed to also use the named parameters pattern, signOut and updateUser.

// [...nextauth].js
...
events: {
- signOut(tokenOrSession),
+ signOut({ token, session }), // token if using JWT, session if DB persisted sessions.
- updateUser(user)
+ updateUser({ user })
}

Introduced in https://github.com/nextauthjs/next-auth/releases/tag/v4.0.0-next.20

JWT configuration​

We have removed some of the configuration options when using JSON Web Tokens, here's the PR for more context.

export default NextAuth({
  // ...
  jwt: {
    secret,
    maxAge,
-   encryptionKey
-   signingKey
-   encryptionKey
-   verificationOptions
    encode({
        token
        secret
        maxAge
-       signingKey
-       signingOptions
-       encryptionKey
-       encryptionOptions
-       encryption
    }) {},
    decode({
        token
        secret
-       maxAge
-       signingKey
-       verificationKey
-       verificationOptions
-       encryptionKey
-       decryptionKey
-       decryptionOptions
-       encryption
    }) {}
  }
})

Logger API​

The logger API has been simplified to use at most two parameters, where the second is usually an object (metadata) containing an error object. If you are not using the logger settings you can ignore this change.

// [...nextauth.js]
import log from "some-logger-service"
...
logger: {
- error(code, ...message) {},
+ error(code, metadata) {},
- warn(code, ...message) {},
+ warn(code) {}
- debug(code, ...message) {}
+ debug(code, metadata) {}
}

Introduced in https://github.com/nextauthjs/next-auth/releases/tag/v4.0.0-next.19

nodemailer​

Like typeorm and prisma, nodemailer is no longer included as a dependency by default. If you are using the Email provider you must install it in your project manually, or use any other Email library in the sendVerificationRequest callback. This reduces bundle size for those not actually using the Email provider. Remember, when using the Email provider, it is mandatory to also use a database adapter due to the fact that verification tokens need to be persisted longer term for the magic link functionality to work.

Introduced in https://github.com/nextauthjs/next-auth/releases/tag/v4.0.0-next.2

Theme​

We have added some basic customization options to our built-in pages like signin, signout, etc.

These can be set under the theme configuration key. This used to be a string which only controlled the color scheme option. Now it is an object with the following options:

theme: {
  colorScheme: "auto", // "auto" | "dark" | "light"
  brandColor: "", // Hex color value
  logo: "" // Absolute URL to logo image
}

The hope is that with some minimal configuration / customization options, users won't immediately feel the need to replace the built-in pages with their own.

More details and screenshots of the new theme options can be found under configuration/pages.

Introduced in #2788

Session​

The session.jwt: boolean option has been renamed to session.strategy: "jwt" | "database". The goal is to make the user's options more intuitive:

  1. No adapter, strategy: "jwt": This is the default. The session is saved in a cookie and never persisted anywhere.
  2. With Adapter, strategy: "database": If an Adapter is defined, this will be the implicit setting. No user config is needed.
  3. With Adapter, strategy: "jwt": The user can explicitly instruct next-auth to use JWT even if a database is available. This can result in faster lookups in compromise of lowered security. Read more about: https://next-auth.js.org/faq#json-web-tokens

Example:

session: {
- jwt: true,
+ strategy: "jwt",
}

Introduced in #3144

Adapters​

Most importantly, the core next-auth package no longer ships with typeorm or any other database adapter by default. This brings the default bundle size down significantly for those not needing to persist user data to a database.

You can find the official Adapters in the packages directory in the primary monorepo (nextauthjs/next-auth). Although you can still create your own with a new, simplified Adapter API.

If you have a database that was created with a 3.x.x or earlier version of NextAuth.js, you will need to run a migration to update the schema to the new version 4 database model. See the bottom of this migration guide for database specific migration examples.

  1. If you use the built-in TypeORM or Prisma adapters, these have been removed from the core next-auth package. Thankfully the migration is easy; you just need to install the external packages for your database and change the import in your [...nextauth].js.

The database option has been removed, you must now do the following instead:

// [...nextauth].js
import NextAuth from "next-auth"
+ import { TypeORMLegacyAdapter } from "@next-auth/typeorm-legacy-adapter"

...
export default NextAuth({
-  database: "yourconnectionstring",
+  adapter: TypeORMLegacyAdapter("yourconnectionstring")
})

  1. The prisma-legacy adapter has been removed, please use the @next-auth/prisma-adapter instead.

  2. The typeorm-legacy adapter has been upgraded to use the newer adapter API, but has retained the typeorm-legacy name. We aim to migrate this to individual lighter weight adapters for each database type in the future, or switch out typeorm.

  3. MongoDB has been moved to its own adapter under @next-auth/mongodb-adapter. See the MongoDB Adapter docs.

Introduced in https://github.com/nextauthjs/next-auth/releases/tag/v4.0.0-next.8 and #2361

Adapter API​

This does not require any changes from the user - these are adapter specific changes only

The Adapter API has been rewritten and significantly simplified in NextAuth v4. The adapters now have less work to do as some functionality has been migrated to the core of NextAuth, like hashing the verification token.

If you are an adapter maintainer or are interested in writing your own adapter, you can find more information about this change in #2361 and release https://github.com/nextauthjs/next-auth/releases/tag/v4.0.0-next.22.

Schema changes​

The way we save data with adapters have slightly changed. With the new Adapter API, we wanted to make it easier to extend your database with additional fields. For example if your User needs an extra phone field, it should be enough to add that to your database's schema, and no changes will be necessary in your adapter.

  • created_at/createdAt and updated_at/updatedAt fields are removed from all Models.
  • user_id/userId consistently named userId.
  • compound_id/compoundId is removed from Account.
  • access_token/accessToken is removed from Session.
  • email_verified/emailVerified on User is consistently named emailVerified.
  • provider_id/providerId renamed to provider on Account
  • provider_type/providerType renamed to type on Account
  • provider_account_id/providerAccountId on Account is consistently named providerAccountId
  • access_token_expires/accessTokenExpires on Account renamed to expires_at
  • New fields on Account: token_type, scope, id_token, session_state
  • verification_requests table has been renamed to verification_tokens
See the changes

Database migration​

NextAuth.js v4 has a slightly different database schema compared to v3. If you're using any of our adapters and want to upgrade, you can use on of the below schemas.

They are designed to be run directly against the database itself. So instead of having one in Prisma syntax, one in TypeORM syntax, etc. we've decided to just make one for each underlying database type. i.e. one for Postgres, one for MySQL, one for MongoDB, etc.

MongoDB​

MongoDB is a document database and as such new fields will be automatically populated. You do, however, need to update the names of existing fields which are going to be reused.

db.getCollection('accounts').updateMany({}, {
  $rename: {
    "provider_id": "provider",
    "provider_account_id": "providerAccountId",
    "user_id": "userId",
    "access_token_expires": "expires_at"
  }
})
db.getCollection('users').updateMany({}, {
  $rename: {
    "email_verified": "emailVerified"
  }
})
db.getCollection('sessions').updateMany({}, {
  $rename: {
    "session_token": "sessionToken",
    "user_id": "userId"
  }
})

Missing secret​

NextAuth.js used to generate a secret for convenience, when the user did not define one. This might have been useful in development, but can be a concern in production. We have always been clear about that in the docs, but from now on, if you forget to define a secret property in production, we will show the user an error page. Read more about this option here

You can generate a secret to be placed in the secret configuration option via the following command:

$ openssl rand -base64 32

Therefore, your NextAuth.js config should look something like this:

/pages/api/auth/[...nextauth].js
...
export default NextAuth({
  ...
  providers: [...],
  secret: "LlKq6ZtYbr+hTC073mAmAh9/h2HwMfsFo4hrfCx5mLg=",
  ...
})

Introduced in #3143

Session strategy​

We have always supported two different session strategies. The first being our most popular and default strategy - the JWT based one. The second is the database adapter persisted session strategy. Both have their advantages/disadvantages, you can learn more about them on the FAQ page.

Previously, the way you configured this was through the jwt: boolean flag in the session option. The names session and jwt might have been a bit overused in the options, and so for a clearer message, we renamed this option to strategy: "jwt" | "database", it is still in the session object. This will hopefully better indicate the purpose of this option as well as make very explicit which type of session you are going to use.

See the session option docs for more details.

Introduced in #3144

Summary​

We hope this migration goes smoothly for each and every one of you! If you have any questions or get stuck anywhere, feel free to create a new issue on GitHub.
