Welcome to Day 3 of 30 days of Next JS!

Today, we will be diving into Next Auth, a complete authentication solution for Next.js. Next Auth provides a simple and secure way to add authentication to your Next.js apps with built-in support for various authentication providers such as Google, Facebook, Twitter, GitHub, and more.

Getting Started with Next Auth

To get started with Next Auth, first install the necessary packages:

npm install next-auth
npm install next-auth-provider

After installing the packages, you can set up your Next.js app to use Next Auth by creating a new file for the authentication configuration. Here’s an example of how you can set up Next Auth in your Next.js app:

import NextAuth from 'next-auth';
import Providers from 'next-auth/providers';

export default NextAuth({
  providers: [
    Providers.Google({
      clientId: process.env.GOOGLE_CLIENT_ID,
      clientSecret: process.env.GOOGLE_CLIENT_SECRET
    }),
    // Add other providers as needed
  ],
  // Other configuration options
});

Once you have set up the authentication configuration, you can use the `useSession` hook to access the user’s session data in your Next.js pages. For example:

import { useSession, signIn, signOut } from 'next-auth/client';

function Profile() {
  const [session, loading] = useSession();

  if (loading) {
    return 
Loading...
;
  }

  if (!session) {
    return 
Please sign in to access this page
;
  }

  return (
    

      
Welcome, {session.user.name}
       signOut()}>Sign out
    
  );
}

export default Profile;
