Refactoring Admin Dashboard to Customer Portal

http://localhost:3000/api/auth/signin

Ok before i go any further i want to adapt this feature so that it's not an admin dashboard but it's a customer portal, i want toget it working first as it is and then refactor for my purpose but i want omake sure that the auth isn't exclusive to me and that i can create user accounts

ChatGPT said: That's a smart move — get it working first, then refactor for your actual use case. Here's a breakdown of what you've got and what you'll need to consider to adapt the admin-style dashboard into a proper customer portal with multi-user support.

✅ Current Auth Setup (Likely State) Right now, based on the project structure and example, your app probably uses:

• NextAuth.js with GitHub provider

• Only you can sign in (hardcoded email check in middleware or session logic)

• Users aren’t stored or used for access control beyond the GitHub session

🧭 What You Want (Customer Portal Goals) You’re aiming for:

🔍 Immediate To-Do for a Customer-Friendly Auth

Before refactoring the rest of the UI:

1. Create a users Table (if not done yet) You can use this schema to start:

CREATE TABLE users (
  id SERIAL PRIMARY KEY,
  email VARCHAR(255) NOT NULL UNIQUE,
  name VARCHAR(255),
  username VARCHAR(255),
  created_at TIMESTAMP DEFAULT now()
);

2. Update Auth Callback to Save Users In your auth.ts (or [...nextauth]/route.ts), add a signIn or jwt/session callback to:

• Automatically insert new users into the DB if they don’t exist

• Fetch user details into the session

import { db } from '@/customer-portal/lib/db';
 
callbacks: {
  async signIn({ user }) {
    const existingUser = await db.query(
      'SELECT * FROM users WHERE email = $1',
      [user.email]
    );
 
    if (!existingUser.rowCount) {
      await db.query(
        'INSERT INTO users (email, name) VALUES ($1, $2)',
        [user.email, user.name]
      );
    }
 
    return true;
  },
  async session({ session }) {
    // attach user info to session
    return session;
  },
}

You may already be using Prisma or Drizzle — adapt to your ORM or SQL helper.

3. Remove Hardcoded Auth Email Checks If somewhere in the code you have:

if (session?.user.email !== 'you@domain.com') {
  redirect('/login');
}

Replace with a generic if (!session?.user) or check user roles later instead.

4. Optional: Add Roles (admin/customer) Add a role column if needed:

ALTER TABLE users ADD COLUMN role TEXT DEFAULT 'customer';

Then assign roles during user creation:

await db.query(
  'INSERT INTO users (email, name, role) VALUES ($1, $2, $3)',
  [user.email, user.name, 'customer']
);

This way you can control admin access later.

1. ✅ Summary: What to Do Next
2. ✅ Seed DB and confirm login works
3. ✅ Add users table
4. ✅ Update auth to store new users
5. ✅ Remove any hardcoded admin checks
6. 🛠 (Later) Tie product data to users if needed
7. 🛠 (Later) Refactor dashboard for customer-facing UI

If you show me the auth.ts config or [...nextauth] route, I can help patch it for multi-user setup immediately.

🔧 Step-by-Step: Support Multiple Users

1. Add a callbacks block to NextAuth Update your NextAuth() config like this:

import NextAuth from 'next-auth';
import GitHub from 'next-auth/providers/github';
 
export const { handlers, signIn, signOut, auth } = NextAuth({
  providers: [GitHub],
  callbacks: {
    async signIn({ user, account, profile }) {
      // Optionally check profile/email domain
      return true; // Allow all GitHub users
    },
    async session({ session, token }) {
      // Attach user ID or role to session
      return session;
    },
    async jwt({ token, user, account }) {
      // Persist user info to JWT
      return token;
    }
  }
});

2. Automatically Store New Users in Your DB If you want to store new users in your own users table (Postgres), you’ll need to add a events handler or use signIn() callback to upsert into your database.

Example with Drizzle:

import { db } from './db';
import { users } from './schema';
 
callbacks: {
  async signIn({ user }) {
    if (user?.email) {
      await db.insert(users).values({
        email: user.email,
        name: user.name ?? '',
        username: user.name?.toLowerCase().replace(/\s+/g, '_') ?? null
      }).onConflictDoNothing();
    }
    return true;
  }
}

You can adjust this based on your ORM (e.g., Prisma, Drizzle, raw SQL).

🧪 Summary

Right now, your auth setup is technically already multi-user — any GitHub user can sign in if you allow it. But to make it truly multi-user for a customer portal:

• ✅ Ensure the DB has a users table

• ✅ In the signIn() callback, insert or find the user in your database

• ✅ In the session() callback, optionally attach extra info (like user ID or role)

Sounds good! You've made great progress so far. When you're ready to pick it back up — whether it's finalizing the auth flow, adapting it to a customer-facing portal, or wiring up the database — just drop your context here and I’ll jump back in with you.

Catch you later, and good luck in the meantime! 🚀
