Rethinking Responsive SVG

If you haven’t seen Joe Harrison’s responsive icons technique yet, you’ll most probably be impressed as much as I was when I first discovered it. In this article, I’d like to explore what we can do with SVG beyond “traditional” scalable vector graphics that are used to replace bitmap PNGs.

Rethinking Responsive SVG

In fact, we can see SVG as an independent module that encapsulates CSS for the customization of views as well as the responsive behavior that also encapsulates JavaScript for the interaction logic. Now, let’s dig a bit deeper into this technique.

A Detailed Introduction To Custom Elements

You’ve probably heard all the noise about Web Components and how they’re going to change Web development forever. If you haven’t, you’ve either been living under a rock, are reading this article by accident, or have a full, busy life which doesn’t leave you time to read about unstable and speculative Web technologies. Well, not me.

A Detailed Introduction To Custom Elements

Web Components are a suite of connected technologies aimed at making elements reusable across the Web. The lion’s share of the conversation has been around Shadow DOM, but probably the most transformative technology of the suite is Custom Elements, a method of defining your own elements, with their own behavior and properties.

Creating A Client-Side Shopping Cart

Session storage is a new feature introduced by the W3C’s “Web Storage” specification. It’s supported in Internet Explorer 8+, Firefox, Chrome, Safari and Opera Desktop (for a complete list, please consult “Can I Use”).

var total = parseInt( sessionStorage.getItem( "total" ) );
var quantity = 2;
var updatedTotal = total * quantity;
sessionStorage.setItem( "total", updatedTotal ); // '240', a string

In this series of articles, we’ll cover in depth a practical implementation of session storage by creating a complete e-commerce shopping cart with the sessionStorage object and jQuery.

How To Build A CLI Tool With Node.js And PhantomJS

In this article, we’ll go over the concepts and techniques required to build a command line tool using Node.js and PhantomJS. Building a command line tool enables you to automate a process that would otherwise take a lot longer.

Build A CLI Tool With Node.js And PhantomJS

Command line tools are built in a myriad of languages, but the one we’ll focus on is Node.js. For those short on time, I’ve condensed the core process into three steps. This is the secret sauce to convert your Node.js script into a fully functioning command line tool. But do stick around to see what else I have to show you.

Introducing Live Extensions For Better-DOM: What They Are And How They Work

After recently writing an article on “Writing A Better JavaScript Library For The DOM”, I realized that the topic is indeed a very complex one and that it's important to understand what exactly live extensions are and how they work.

Introducing Live Extensions For Better-DOM: What They Are And How They Work

In today's article, I will answer most questions that were asked regarding "live extensions" and help you get going with this new concept.

Understanding JavaScript’s Function.prototype.bind

Function binding is probably your least concern when beginning with JavaScript, but when you realize that you need a solution to the problem of how to keep the context of this within another function, then you might not realize that what you actually need is Function.prototype.bind().

render: function () {

    this.getAsyncData(function () {

        this.specialFunction();

        this.anotherSpecialFunction();

    }.bind(this));

}

The first time you hit upon the problem, you might be inclined to set this to a variable that you can reference when you change context. Many people opt for self, _this or sometimes context as a variable name. They’re all usable and nothing is wrong with doing that, but there is a better, dedicated way.

Writing A Better JavaScript Library For The DOM

At present, jQuery is the de facto library for working with the document object model (DOM). It can be used with popular client-side MV* frameworks (such as Backbone), and it has a ton of plugins and a very large community.

Writing A Better JavaScript Library For The DOM

As developers’ interest in JavaScript increases by the minute, a lot of people are becoming curious about how native APIs really work and about when we can just use them instead of including an extra library. Lately, I have started to see more and more problems with jQuery, at least my use of it.

An Introduction To Full-Stack JavaScript

Nowadays, with any Web app you build, you have dozens of architectural decisions to make. And you want to make the right ones: You want to use technologies that allow for rapid development, constant iteration, maximal efficiency, speed, robustness and more.

An Introduction To Full-Stack JavaScript

You want to be lean and you want to be agile. You want to use technologies that will help you succeed in the short and long term. And those technologies are not always easy to pick out. In my experience, full-stack JavaScript hits all the marks.

The Future Of Video In Web Design

Federico was the only other kid on the block with a dedicated ISDN line, so I gave him a call. It had taken six hours of interminable waiting (peppered with frantic bouts of cursing), but I had just watched 60 choppy seconds of the original Macintosh TV commercial in Firefox, and I had to tell someone. It blew my mind.

The Future Of Video In Web Design

Video on the Web has improved quite a bit since that first jittery low-res commercial I watched on my Quadra 605 back in 7th grade. But for the most part, videos are still separate from the Web, cordoned off by iframes and Flash and bottled up in little windows in the center of the page. They’re a missed opportunity for Web designers everywhere.
