Methods & Parameters

TODO

Usage

To add NextAuth.js to a project create a file called [...nextauth].js in pages/api/auth.

/**
 * @file
 * pages/api/[...nextauth].js
 * */

import NextAuth from "next-auth";
import {adgangsplatformen, callbacks} from "@dbcdk/login-nextjs";
import CONFIG from "../config";

const options = {
  providers: [
    adgangsplatformen({
      clientId: CONFIG.clientId,
      clientSecret: CONFIG.clientSecret,
    }),
  ],
  callbacks: {
    ...callbacks,
  },
};

export default (req, res) => NextAuth(req, res, options);

adgangspaltformen is the provider function using login.bib.dk with next through next-auth and requires a ClientId and clientSecret

The provider automatically uses a CULR ID (from login.bib.dk it is called uniqueId) as profile ID. If another ID should be used or further validation is needed a custom profile function can be used:

adgangsplatformen({
      clientId: CONFIG.clientId,
      clientSecret: CONFIG.clientSecret,
      profile: ({id, profile}) => {
        //custom logic here
        return {id: 'some-valid-id'}
      }
    }),

callbacks contains next-auth specific callbacks that will expose the token recieved from login.bib.dk and redirect to login.bib.dk/logout at logout (See the specific implementation here).

For more information about callbacks see https://next-auth.js.org/configuration/callbacks

Client

The client library exposes two functions signIn and signOut that are wrappers around next-auth's signIn and signOut functions.

import {signIn} from "next-auth/client";

export default () => (
  <button onClick={() => signIn()}>Sign in with login.bib.dk</button>
);

import {signOut} from "next-auth/client";

export default () => <button onClick={() => signOut()}>Sign out</button>;
