Offline installation of npm packages
January 2, 2016 Occasionally, you may need to install npm packages while offline. This could be due to a flaky network connection, being on a flight or during a workshop. Getting this working has been a dream for a while. They say you should follow your dreams. Unless it's been a while and they haven't followed you back, in which case unfollow them and move on. Luckily, there are a few options ava
Explorations In Automatically Fixing JavaScript Linting-errors
Explorations In Automatically Fixing JavaScript Linting-errors September 30, 2014 Linting is a common step in our JavaScript iteration workflow. Most developers probably use JSHint (or ESLint) for this purpose. However, when a tool is capable of informing you of linting issues, the next logical question is..why can't it fix these issues for us? Is this taking automation too far, or a logical compl
Detect, Undo And Redo DOM Changes With Mutation Observers
Detect, Undo And Redo DOM Changes With Mutation Observers June 4, 2014 I’ve been wondering why DOM Mutation Observers, which can monitor changes to one or more DOM elements and return a report of what changed, aren’t used more often in the wild. Mutation Observers have long-replaced DOM Mutation Events (which were deemed slow, verbose and crashy), are fairly well documented and a polyfill for IE9

Patterns For Large-Scale JavaScript Application Architecture
Today we're going to discuss an effective set of patterns for large-scale JavaScript application architecture. The material is based on my talk of the same name, last presented at LondonJS and inspired by previous work by Nicholas Zakas. Who am I and why am I writing about this topic? I'm currently a JavaScript and UI developer at AOL helping to plan and write the front-end architecture to our nex
Full-Stack JavaScript With MEAN And Yeoman
December 12, 2013 Introduction A trend proliferating amongst prototypers in the Angular community is full-stack JavaScript development via the MEAN stack. The acronym stands for: (M)ongoDB - a noSQL document datastore which uses JSON-style documents to represent data, (E)xpress - a HTTP server framework on top of Node, (A)ngular - as you know, the JS framework offering declarative, two-way databin
Visualising JavaScript Processing Over Time With DevTools Flame Charts
Visualising JavaScript Processing Over Time With DevTools Flame Charts In this quick video, I walk through how to effectively use DevTools Flame Charts for visually representing your app's JavaScript processing over time. This can be useful if you're concerned it may be suffering from particularly long function executions and you want to dive into them further. Flame Charts compliment the existing

DevTools Extensions For Web App Developers
March 26, 2013 The past year has seen many leaps made to improve developer productivity through better tooling. We're paying increasing attention to our workflow and many of us have spent time optimising our usage of tools like Grunt, Bower, Yeoman and the terminal. Another important area worth spending time on is your debugging workflow - if you're like me, this starts with the Chrome DevTools. W
[O'REILLY]Developing Backbone.js Applications -
Available free for open-source reading below or for purchase via the O'Reilly store. Pull requests and comments always welcome. Prelude Not so long ago, “data-rich web application” was an oxymoron. Today, these applications are everywhere and you need to know how to build them. Traditionally, web applications left the heavy-lifting of data to servers that pushed HTML to the browser in complete pag
DevTools: Visually Re-engineering CSS For Faster Paint Times
February 7, 2013 Increasingly, whether it’s on desktop or mobile, users want their web experience to be snappy and delightful. This means that even if the browser is busy rendering the page or loading in content, the user should still be able to scroll around and interact with it. Animations need to be silky, scrolling must be buttery-smooth and your page needs to contain little to no jank. This c
Improving Web App Performance With the Chrome DevTools Timeline and Profiles

Yeoman, At Your Service.
September 10, 2012 When kicking off a new application, we always seem to have libraries we need to manually find and add, boilerplate code that needs to be written and a thorough build and testing process we need to get setup. Today we’re excited to announce the launch of Yeoman - a project which hopes to simplify these steps in your developer workflow. Package management At the moment, adding and

Digesting JavaScript MVC - Pattern Abuse Or Evolution?
Digesting JavaScript MVC - Pattern Abuse Or Evolution? June 13, 2012 In my talk from London Ajax, we'll explore the current state of MVC in the JavaScript community, how Smalltalk-80's MVC differed and whether modern frameworks abuse (or evolve) the MVC pattern. We'll also look at a framework that tries to stick more closely to Smalltalk MVC and close up with a panel discussion. http://speakerdeck
ECMAScript 6 Resources For The Curious JavaScripter
May 30, 2012 I’ve recently spent a lot of time looking at EcmaScript 6 and thought it would be useful to put together a short page of resources to help anyone else interested in exploring the next version of JavaScript further. What ES6 features do browsers support right now? Juriy Zaytsev’s ES6 compatibility table is a useful start for establishing what ECMAScript 6 features your browser does and
JavaScript Style Guides And Beautifiers
May 3, 2012 Today we're going to explore JavaScript style guides, specifically: their importance, style guides worth reviewing and tools that can assist in automated code beautification or style enforcement. What exactly is a style guide? Before we begin, let us remind ourselves exactly what a code style guide is: A style guide or style manual is a set of standards for the writing and design of co
