Introduction to the HTTP Module

With many server-side languages, a separate program such as Apache or Nginx accepts the HTTP connection and passes the request on to your code. In Node.js, your own JavaScript can accept the connection directly, through the built-in http module. No package needs to be installed.

This chapter builds web servers with that module alone: this lesson creates a server and sends responses, the next lessons read requests, route URLs to different code, and serve files from disk
