We've come a long way in this chapter about user authentication in Node, and several aspects of deploying and scaling Node applications.
Specifically we covered:
Session management in Connect and Express
Cookie handling in Express
The passport user authentication system
Router middleware in Express
Setting up multiple-data models
The cluster and workforce modules to scale within the server
Using forever to keep a background Node application running
Configuring an LSB-compliant script to start a Node application on Debian at system boot
Deploying applications to AppFog
Tunneling to the database service on AppFog
In the next chapter, we'll be taking the Notes application to a whole new level. We'll be exploring how to bridge between the browser side and server side, using JavaScript code on both ends to create real-time communication between the two.
