Server for node. JS: The first line requests (require) node. js's own HTTP module and assigns it to the HTTP variable. Next we invoke the function provided by the HTTP module: Createserver. This function returns an object that has a method called Listen, which has a numeric parameter that specifies the port number that the HTTP server listens on.

event pattern are also obvious, as it does not conform to the usual linear approach of the developer, often requiring a complete logic split into events, which increases the difficulty of development and debugging. For this issue, the node. JS third-party module presents a number of solutions, which we'll discuss in detail in the 6th chapter. node.
