Auth0

WunderGraph comes with built in support for Auth0. This guide will show you how to configure WunderGraph to use Auth0 as an authentication provider.

Open your project's wundergraph.config.ts and scroll down to the authentication object. Inside the nested cookieBased object is a nested array object called providers. Inside this array, add an auth0 auth provider as shown below:

// ...
authentication: {
  cookieBased: {
    providers: [
      authProviders.auth0({
        id: 'auth0', // unique id for this provider
        issuer: new EnvironmentVariable('AUTH0_ISSUER'),
        clientId: new EnvironmentVariable('AUTH0_CLIENT_ID'),
        clientSecret: new EnvironmentVariable('AUTH0_CLIENT_SECRET'),
      }),
    ];
  }
}
// ...

The openIDConnect function takes the following arguments:

• id: an unique id that identifies the provider, used to reference the provider in the clients
• issuer: the issuer provided by your identity provider
• clientId: the client ID provided by your identity provider
• clientSecret: the client secret provided by your identity provider

On production you have to configure cookie keys and crsf token secret to make sure your application is secure, read more.

Once configured you can use the WunderGraph client to authenticate users in your application.

The login function takes the provider id as the first argument and a redirectURL as the second argument. Calling the login function will initiate the authentication flow and redirect the user to the identity provider, after succesful authentication the user will be redirected back to the provided redirectURL or the default redirectURL configured at the provider.

TypeScript Client

import { createClient } from '.wundergraph/generated/client';

const client = createClient();

client.login('auth0');

Next.js Example

import { useAuth } from 'components/generated/nextjs';

export default function Page() {
  const { login } = useAuth();

  return <button onClick={() => login('auth0')}>Login with Auth0</button>;
}

The logout method can be used to log out the current user. By default this will only remove the authentication cookie from the browser. If you want to log out the user from the identity provider as well, you can pass the logoutOpenidConnectProvider option.

TypeScript Client

client.logout({
  logoutOpenidConnectProvider: true,
});

Next.js Example

import { useAuth } from 'components/generated/nextjs';

export default function Page() {
  const { logout } = useAuth();

  return <button onClick={() => logout({ logoutOpenidConnectProvider: true })}>Logout</button>;
}

You can customize the authentication flow by using hooks. For example to create a new user in your database after a successful authentication.

export default configureWunderGraphServer(() => ({
  hooks: {
    authentication: {
      postAuthentication: async ({ user, log }) => {
        log.info(`User ${user.id} has been authenticated`);
      },
    },
  },
}));
