next-iron-session - Authentication example

This example creates an authentication system that uses a signed and encrypted cookie to store session data.

It uses current best practices as for authentication in the Next.js ecosystem:
1. no `getInitialProps` to ensure every page is static
2. `useUser` hook together with `swr` for data fetching

Features

• Logged in status synchronized between browser windows/tabs
• Layout based on logged in status
• All pages are static
• Session data is signed and encrypted in a cookie

Steps to test the functionality:

1. Click login and enter your GitHub username.
2. Click home and click profile again, notice how your session is being used through a token stored in a cookie.
3. Click logout and try to go to profile again. You'll get redirected to the `/login` route.
