Web Developer's Reference Guide

By: Joshua Johanan, Talha Khan, Ricardo Zea

Overview of this book

This comprehensive reference guide takes you through each topic in web development and highlights the most popular and important elements of each area. Starting with HTML, you will learn key elements and attributes and how they relate to each other. Next, you will explore CSS pseudo-classes and pseudo-elements, followed by CSS properties and functions. This will introduce you to many powerful and new selectors. You will then move on to JavaScript. This section will not just introduce functions, but will provide you with an entire reference for the language and paradigms. You will discover more about three of the most popular frameworks today—Bootstrap, which builds on CSS, jQuery which builds on JavaScript, and AngularJS, which also builds on JavaScript. Finally, you will take a walk-through Node.js, which is a server-side framework that allows you to write programs in JavaScript.

The HTTP module


We will cover the HTTP server module. Technically, you could write your HTTP server using the net module, but you do not have to.

Some of these functions are very similar to the net module functions. This should make sense as HTTP, at its core, is a network server.

All of these functions and objects are also used with the HTTPS module. The only difference is that for the options of createServer and https.request, you can pass certificates.

All of the following examples assume that the module has been loaded:

var http = require('http');

createServer

This creates an HTTP server:

http.createServer([requestListener])

Return Value

This returns an http.Server object.

Description

Much like net.createServer, this is required to serve anything. The requestListener parameter is attached to the request event.

Here is a simple example that just logs to the console any time a request is made:

var server = http.createServer(function (req, res) {
    console.log('Someone made a request!');
    res.end...
