  • What happens to persistent-notes when mongodb is not running when the app is started? What if it is shut down while the app is running?
    • You can stop and start mongodb by typing sudo service mongodb stop and sudo service mongodb start.
  • When does the app open a connection to MongoDB? Note that it happens twice.
  • You'll notice that restarting the app preserves current sessions. How can you disconnect from a session manually (without "logging out") from the browser? How can you terminate a select session from the server? What about all sessions?
