AngularJS’s Controller As and the vm Variable


The great thing about coding is that we are able to mix coding style and personal/team preference together. This post is all about a preference of mine that has helped me stick to be principles of readable, efficient, and maintainable code with AngularJS. It’s no secret that I am a fan of the “Controller As” syntax that was revealed in AngularJS 1.2.0, in fact I wrote an entire post about the Controller As feature. I’m also a fan of readable code and keeping things consistent and simple. We tend to spend a lot of time reading code. In fact, I […]

Easy Fix to a Common Angular Module Error


I love running my code right after making some new changes, so I can see them light up in the browser. But I don’t love when error messages are not straight forward. At least not to me. Recently I ran a project and was told ngLocale is not available! What? I’m not loading ngLocale, what does Angular want from me? After some digging in the console and Chrome debugger I uncovered more information about the issue. “[$injector:nomod] Module ‘ngLocale’ is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you […]

Gulp and Grunt at AngleBrackets


I love JavaScript and task automation is a key ingredient to building awesome browser based apps. Today I presented how I prefer to do task automation using gulp.js and contrasted it to grunt.js at AngleBrackets, a newer web conference. I’ll be blogging more about these and putting a course out, but for now here are the slides from the conference and you can find the grunt and gulp demos here.

New Breeze Angular Service


The world of JavaScript changes at a fast pace and in the time since my Angular and Breeze Part 1 and Angular and Breeze Part 2 Pluralsight courses have been released, both libraries have had some revisions. One such revision is worth making some changes in your code. The good news is that the folks at Angular and Breeze made it easier on us all. This post explains the changes and how you can refactor your code quickly to work with the latest Angular and Breeze libraries. Short Version With HotTowel.Angular.Breeze 2.1.0 (and prior), we used to need these 3 […]

Angular App Structuring Guidelines


App Structure I find it extremely helpful to have an idea of what is important to me and my team in structuring my app instead of focusing on the actual structure. You have to find your own path that is comfortable for you and your team. Instead of just picking a structure, it’s helpful to think about the “why”, so I’ll walk you through the guidelines I follow and my thought process on why I choose how I do. This is a follow up to my post on Angular Structure. How you organize your structure is up to you. There […]

Angular and Progressive Saving


Last week I had the privilege of presenting at ngConf which was jam packed with some awesome presentations. My presentation was on Progressive Saving with Angular, where you can stash work in progress in local storage and come back to it. It was an abbreviated version of what I present in my Pluralsight course Building Apps with Angular and Breeze Part 1 and Part 2, where I explore this concept in detail. You can watch my presentation here. Here are the slides from my presentation. And you can run the live demo of the app from this link. The conference […]

It’s High Time to Learn Git


It’s time. Admit it. You’ve put it off too long and now that Git is tied at the hip to Visual Studio 2013 and there is some great training on it by my friend Esteban Garcia, it’s time to learn it. I use git for all of my code. You can find Esteban’s new course Git for Visual Studio 2013 at Pluralsight. Git has gained a lot of popularity in the last couple of years and I’m seeing more and more developers adopting it. If you use Visual Studio as your primary IDE, there is a bit of a learning […]
