Summary
We learned a lot in this chapter about Node's HTTP support, and implementing web applications. In particular, we learned about the following topics:
EventEmitters
Listening to HTTP events
A simple web application with no frameworks
The Express application framework
How to deal with computationally intensive code
Constructing a multi-tier application with a REST service
Now we can move on to implementing a more complete application, one for taking notes. We will use the Notes application for several upcoming chapters as a vehicle to explore the Express application framework, database access, deployment to cloud services or on your own server, and user authentication. In the next chapter, we will build the basic infrastructure of a simple Express application.
