This book was borne out of frustration. I have been in software engineering for many years, and when I started learning Node.js and Backbone.js, I learned the hard way that their official documentation and the Internet lack in quick start guides and examples. Needless to say, it was virtually impossible to find all of the tutorials for JS-related modern technologies in one place.
What to Expect
A typical reader of RPJS should expect a collection of quick start guides, tutorials and suggestions (e.g., Git workflow). There is a lot of coding and not much theory. All the theory we cover is directly related to some of the practical aspects, and essential for better understanding of technologies and specific approaches in dealing with them, e.g., JSONP and cross-domain calls.
In addition to coding examples, the book covers virtually all setup and deployment step-by-step.
You'll learn on the examples of Chat web/mobile applications starting with front-end components. There are a few versions of these applications, but by the end we'll put front-end and back-end together and deploy to the production environment. The Chat application contains all of the necessary components typical for a basic web app, and will give you enough confidence to continue developing on your own, apply for a job/promotion or build a startup!
Who This Book is For

If you have always wanted to have a website, there is no better time to achieve your dream than now. Due to advancements in web designing, you do not need to spend years learning HTML; “drag and drop” website builders make everything easy for newbies. Sweetening the deal even further, you can create your website without spending a penny.
However, the difficult part is finding a good provider that will let you make a decent free website. As you may know, “free” usually comes at a cost. In this book, not only will I show you how to create a website, but I will also recommend some of the best free website providers you can sign up with.
Anyone who has ever started a website knows that making it is easy. But, finding motivation to keep it going is the most difficult part. So, I will also give you tips you can follow to keep on creating content. Furthermore, there are sections in the book dealing with website promotion, SEO, and other topics.
Since the internet can be dangerous to young people, I recommend that you communicate to your parents or guardians about your intentions to make a free website. It's even better if they take part in the whole process.

The internet was never intended for you, opines Brian McCullough in this lively narrative of an era that utterly transformed everything we thought we knew about technology. In How the Internet Happened, he chronicles the whole fascinating story for the first time, beginning in a dusty Illinois basement in 1993, when a group of college kids set off a once-in-an-epoch revolution with what would become the first “dotcom.”
Depicting the lives of now-famous innovators like Netscape’s Marc Andreessen and Facebook’s Mark Zuckerberg, McCullough also reveals surprising quirks and unknown tales as he tracks both the technology and the culture around the internet’s rise. Cinematic in detail and unprecedented in scope, the result both enlightens and informs as it draws back the curtain on the new rhythm of disruption and innovation the internet fostered, and helps to redefine an era that changed every part of our lives.
