How to add extra properties to the user and save it to the database?

[vlohar08]

Hi,
I want to add a role to every user that creates an account. I managed to add the role on the client side but the role is not being saved on the database. Is there any way by which I can save the user role in the database?

My code

import NextAuth from "next-auth";
import EmailProvider from "next-auth/providers/email";
import GoogleProvider from "next-auth/providers/google";
import FacebookProvider from "next-auth/providers/facebook";
import TwitterProvider from "next-auth/providers/twitter";
import { MongoDBAdapter } from "@next-auth/mongodb-adapter";
import clientPromise from "@/db/mongodbClient";
import { CustomsendVerificationRequest } from "./signinemail";

export default NextAuth({
  session: {
    strategy: "jwt",
  },
  secret: process.env.NEXTAUTH_SECRET,
  adapter: MongoDBAdapter(clientPromise),
  providers: [
    EmailProvider({
      server: {
        host: process.env.EMAIL_SERVER_HOST,
        port: process.env.EMAIL_SERVER_PORT,
        auth: {
          user: process.env.EMAIL_SERVER_USER,
          pass: process.env.EMAIL_SERVER_PASSWORD,
        },
      },
      from: process.env.EMAIL_FROM,
      sendVerificationRequest({ identifier, url, provider }) {
        CustomsendVerificationRequest({ identifier, url, provider });
      },
    }),
    GoogleProvider({
      clientId: process.env.GOOGLE_CLIENT_ID,
      clientSecret: process.env.GOOGLE_CLIENT_SECRET,
    }),
    FacebookProvider({
      clientId: process.env.FACEBOOK_CLIENT_ID,
      clientSecret: process.env.FACEBOOK_CLIENT_SECRET,
    }),
    TwitterProvider({
      clientId: process.env.TWITTER_ID,
      clientSecret: process.env.TWITTER_SECRET,
      version: "2.0",
    }),
  ],
  pages: {
    signIn: "/login",
    verifyRequest: "/verify-request",
  },
  callbacks: {
    jwt({ token, user }) {
      if (user) {
        user.role = "customer";
        return {
          ...token,
          role: user.role,
        };
      } else {
        return token;
      }
    },
    session({ session, token }) {
      return {
        ...session,
        user: {
          ...session.user,
          role: token.role,
        },
      };
    },
  },
});
