Example Nextjs Firebase authentication application using next-iron-session

Inspired by the with-iron-session example.

This example creates an authentication system that uses a signed and encrypted cookie to store session data. It relies on next-iron-session.

It uses current best practices for authentication in the Next.js ecosystem.

Features:

• Static Generation (SG), recommended example
• Server-side Rendering (SSR) example in case you need it
• Logged in status synchronized between browser windows/tabs using withUser hook and swr module
• Layout based on the user's logged-in/out status
• Session data is signed and encrypted in a cookie

next-iron-session also supports:

• Express / Connect middlewares
• Multiple encryption keys (password) to allow for seamless updates or just password rotation
