Hi @tall bloom. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

To use NextAuth with TypeScript in your Next.js project, you need to set up a specific route for authentication and configure NextAuth.js with your GitHub OAuth credentials and the Prisma adapter. Here's how you can do it:

1. Create a new directory and a new file in the pages/api directory:

mkdir -p pages/api/auth && touch pages/api/auth/[...nextauth].ts

2. In the new pages/api/auth/[...nextauth].ts file, add the following boilerplate to configure your NextAuth.js setup with your GitHub OAuth credentials and the Prisma adapter:

import { NextApiHandler } from 'next';
import NextAuth from 'next-auth';
import { PrismaAdapter } from '@next-auth/prisma-adapter';
import GitHubProvider from 'next-auth/providers/github';
import prisma from '../../../lib/prisma';

const authHandler: NextApiHandler = (req, res) => NextAuth(req, res, options);
export default authHandler;

const options = {
  providers: [
    GitHubProvider({
      clientId: process.env.GITHUB_ID,
      clientSecret: process.env.GITHUB_SECRET,
    }),
  ],
  adapter: PrismaAdapter(prisma),
  secret: process.env.SECRET,
};

3. If you have a custom App, you can use the built-in type AppProps and change the file name to ./pages/_app.tsx:

import type { AppProps } from 'next/app'
 
export default function MyApp({ Component, pageProps }: AppProps) {
 return <Component {...pageProps} />
}

4. For the custom login page, you can use the loginWithMagicLink function from Magic to handle the login process. Here's an example of how you can do it:

import { useContext, useState, useEffect } from 'react';
import { UserContext } from '@/lib/UserContext';
import { useRouter } from 'next/router';
import { magic } from '@/lib/magic';

export default function Login() {
const [user, setUser] = useContext(UserContext);
const [email, setEmail] = useState('');
const router = useRouter();

useEffect(() => {
user?.issuer && router.push('/dashboard');
}, [user]);

const handleLogin = async (e) => {
e.preventDefault();

try {
  const didToken = await magic.auth.loginWithMagicLink({ email, });

  const res = await fetch('/api/login', {
    method: 'POST',
    headers: {
      'Content-type': 'application/json',
      Authorization: `Bearer ${didToken}`,
    },
  });
} catch (error) {
  console.error(error);
}

};

return (
<form onSubmit={handleLogin}>
<label htmlFor="email">Email</label>
<input name="email" type="email" value={email} onChange={(e) => setEmail(e.target.value)} />
<button type="submit">Send Magic Link</button>
</form>
);
}

Please note that you need to replace `'@/lib/UserContext'` and `'@/lib/magic'` with the actual paths to your UserContext and Magic libraries.
