let googleStrategy = new GoogleStrategy(
  {
    clientId: 'YOUR_CLIENT_ID',
    clientSecret: 'YOUR_CLIENT_SECRET',
    redirectURI: 'https://example.com/auth/google/callback',
  },
  async ({ accessToken, refreshToken, extraParams, profile }) => {
    // Get the user data from your DB or API using the tokens and profile
    return User.findOrCreate({ email: profile.emails[0].value })
  },
)

authenticator.use(googleStrategy)

Setup your routes

// app/routes/login.tsx
export default function Login() {
  return (
    <Form action="/auth/google" method="post">
      <button>Login with Google</button>
    </Form>
  )
}

// app/routes/auth.google.tsx
import { redirect, type ActionFunctionArgs } from '@remix-run/node'
import { authenticator } from '~/services/auth.server'

export let loader = () => redirect('/login')

export let action = ({ request }: ActionFunctionArgs) => {
  return authenticator.authenticate('google', request)
}

// app/routes/auth.google.callback.tsx
import type { LoaderFunctionArgs } from '@remix-run/node'
import { authenticator } from '~/services/auth.server'

export let loader = ({ request }: LoaderFunctionArgs) => {
  return authenticator.authenticate('google', request, {
    successRedirect: '/dashboard',
    failureRedirect: '/login',
  })
}
