NodeJS excels at serving HTTP requests. This is because a given request life-cycle spends much time in transit between the client and the server. During this time, Node processes other requests. In this section, we'll look at some of Node's HTTP networking capabilities, and how they fit into the IO event loop.
We'll start with a look at basic HTTP requests, and how they serve as the foundation for many Node modules and projects. Then, we'll move onto streaming responses to the client, instead of sending a giant blob of data all at once. Finally, we'll look at how Node servers can proxy requests to other services.
The http module in NodeJS takes care of all the nitty-gritty details with regard to creating and setting up HTTP servers. It should be no surprise that this module is heavily utilized by many Node projects that create web servers. It even has a helper function that will create the server for us, and setup the callback function that's used to...
