• The 15 Commandments of Front-End Performance

  This list is the product of many years of experience in the front-end web development field. I maintain this list as a reminder to myself to always follow best practices, and to not compromise on performance, even if I’m in a time crunch. I read it before I start any project, and share it with my team at work (sometimes we joke and call them “codemandments”) so we can all be on the same page and do our part to keep the web fast. Feel free to fork this for your own use. The Commandments I will gz

• The Monty Hall Rewrite

  Here at Acme, Inc. we switched to Soy Milk when we rewrote our app, and now it’s 8.3x better than our old Almond Milk app! I call this a Monty Hall Rewrite. What’s a Monty Hall? For those loyal readers who haven’t heard of The Monty Hall Problem, to which I’m alluding, it comes from an old game show, called Let’s Make A Deal. It later became an interesting probability question, and even later a less interesting common interview question. On Let’s Make A Deal (on which Monty Hall was the original

• The Productivity Cycle

  People are interesting. We know so little about ourselves compared to what we’d like to think we know. We’re all subtly different even though we’re, on a whole, overwhelmingly predictable. There are copious studies to back up “average” data from people, and plenty of arm-chair anthropologists and psychologists that have very nice theories on how we tick. But most of us aren’t ‘average,’ and perhaps some of us tock more than we tick (mark this as the first of many “stretches” in this post). I’d l

• Understanding JavaScript Inheritance

  So someone shoulder-taps you and asks you to explain the concepts behind JavaScript Inheritance to them. In my eyes you’ve got a few options. The Terminology Play You mention that it’s prototypal inheritance, not prototypical and pretty much gloss over the rest, comfortable in your superiority in terminology. You may go as far as saying “Objects just come from other Objects because there aren’t any classes.” Then you just link to Crock’s Post on it, and try to seem busy for the next few days. Ma

• Deploying JavaScript Applications

  Preface: Nothing in this post is necessarily new, or even anything I thought of first (save for a name or two). However, I’m writing it because I’d like to start building some consistency and naming conventions around a few of the techniques that I am using (and are becoming more common), as well as document some processes that I find helpful. Much of this comes from my experience deploying applications at Bazaarvoice as a large third party vendor, and should probably be tailored to your specifi

• Introducing The Jed Toolkit

  The Jed Internationalization Toolkit The Jed Toolkit is a collection of interoperable tools to help facilitate the full process of internationalizing applications in JavaScript. These tools have a wide range of utility, from small modules to help format messages, dates, and numbers to services that facilitate translation, and code integration. The goal of the project is to bring the experience and quality of internationalizing JavaScript applications up to par with the rest of the current state

• Third Party JavaScript In The Third Person

  At the end of last year I spoke at the awesome CapitolJS Conference in DC. I was encouraged to talk a little more broadly about third-party JavaScript development and its various quirks. When I got back home to AustinJS we had some time for a short talk. Luckily, Logan Lindquist is usually there to film talks for Austin Tech Videos. Long story short, my talk and slides are now available for Third Party JavaScript in the Third Person. The slides are available (likely in webkit) at: alexsexton.com

• Third Party Front-end Performance

  I work for a company called Bazaarvoice. Our core products (Ratings and Reviews is our biggest) are all implemented as third party javascript applications. We are white-label, so you don’t see a ton of our brand around, but we power the User Generated Content (UGC) behind Walmart, Samsung, Best Buy, Proctor & Gamble, etc, etc. Needless to say, we have one of the highest volume third party applications on the internet. Fun stuff. There are other massively successful and smart companies doing simi

• The UX of Language

  I once read a tweet that I haven’t been able to attribute back to its original source (Paul Irish has sleuthed and found the original source to be a Greg Brockman tweet), but said something along the lines of Web programming is the science of coming up with increasingly complicated ways of concatenating strings. I think that there’s a good reason for this. As we turn to the next chapter of the web and start building more web applications, rather than just web documents, we begin to need to mix l

• My Thoughts on AMD

  So I know it was cool to write blog posts about AMD (A CommonJS JavaScript Module Specification) like a month ago, but I’ve recently had the desire to put my two cents into the discussion. I am likely not entirely objective – as I frequently use RequireJS and have even committed tiny little parts to the project that James likely had to rewrite. I would like to point out up front, though, that AMD !== RequireJS. RequireJS is an implementation of AMD plus a whole ecosystem of usefulness. I recentl

• Uselessware :: A Brief History (JSConf 2011 Talk)

  I felt like linking up this talk that I gave on Track B of JSConf in Portland this past year. I feel passionately about the value of writing code that serves no useful purpose other than to bring joy and skills to its implementors and users. The talk is pretty short :D

• Breaking The Cross Domain Barrier (Screencast)

  I decided to try my hand at doing a screencast. I have been told my old cross-domain talk slides have always needed a little more context, so I did that. Hopefully I’ll get in the habit of doing these, they’re not so difficult. Enjoy! Breaking The Cross Domain Barrier from SlexAxton on Vimeo.

• Breaking The Cross Domain Barrier (or half of it anyways)

  I gave a talk at TXJS and AustinJS about cross domain communication in JavaScript. Here is a video that stopped halfway through that talk. Breaking The Cross Domain Barrier from yayQuery on Vimeo. The slides are available here: Breaking The Cross Domain Barrier Sorry for the half-vid, and low quality, but I figured it was worth putting out there, as I’ve had a few requests for it and I’m running out of hard drive space. Perhaps with any pressure, I’d do a screencast. Also, this was the day that

• An Accessible Way To Stop Your Content From Flashing (FOUC)

  There are a lot of different reasons why you might see content flash on your page before it’s done loading. The flash that I’m talking about usually happens when you are trying to build a JavaScript widget that gracefully degrades when JavaScript is off. You probably feel pretty cool about yourself for writing your JS in an accessible way, but you are sad that it hurts the user experience. One of the most common examples of this situation happens with tabbed interfaces, and more specifically the

• What I Learned about the Google Chrome Store

  While traveling in Europe this week, I had the pleasure of going to a Google Chrome developer event put on by Mike Mahemoff (The Moff™) and Paul Kinlan (whom Paul Irish says is a genius, so that’s a good start). I took some notes during the meeting. I didn’t know tooo much about the chrome app store, so I figured I’d post what I learned in a very digestible manner for anyone who’s googling for the right keywords next week. A bulleted list of things I learned at the meetup (other than how strong

• On "Rolling Your Own" Large jQuery Apps

  As a preface, make sure you’ve read my super-smart and talented yayQuery co-host Rebecca Murphey’s blog post on this topic here: On jQuery Large Applications and here: On Rolling Your Own. Rebecca points out some huge holes in the jQuery-verse when it comes to large-application development, and gives her opinion on why she doesn’t think jQuery is ever a good fit for a large application. I disagree, and she’s successfully convinced me to write a post on why I think what I do, so here we are. Also

• TXJS and ScriptJunkie

  I have been pretty neglectful of my blog since I started at Bazaarvoice, but I think I’m going to try to pick up a little bit. That being said, here’s a short update. I am now a featured author on ScriptJunkie – a new website from Microsoft about front end development. Check out my post “Building and Maintaining Large JavaScript Applications” I’ll likely cover a few more topics concerning large application structure in the future, both on my blog and on yayQuery and ScriptJunkie.

• Using Inheritance Patterns to Organize Large jQuery Applications

  I want to introduce/reinforce a pattern for developing large applications with jQuery. I did not invent any of this, but I find that the resources that describe this technique are few and far-between.– so I’m taking a shot at it. By and large, when using jQuery, developers seem to forget the paradigms they learned for well structured code in other languages. This is likely due to the fact that jQuery is effectively neutral when it comes to your structural methodology or inheritance patterns, and
