A few weeks ago, I made this nice little side-bar that allowed a user to click an element and then perform actions on that element. They could also add new elements.
The idea of showing a quick animation for when a new element is animated using Angular’s animation framework sounded easy. However, it turned out to be problematic.

If you’ll recall my previous post on building a simple menu navigation system with Angular, I alluded to advanced scenarios such as determining when, or if, a user can navigate away from the current state.
There are many ways to prevent a user from changing state, but providing reusable mechanisms/services to achieve a unified solution should be our goal.

One of the best features of Angular is also one of its most impactful on performance. That feature is two-way binding.
To achieve two-way binding Angular “watches” for when JavaScript objects change and when the DOM values change during Angular’s digest cycle. It’s not an extremely complex mechanism, conceptually, but it’s very effective.

The Covenant Health Knoxville Marathon / marathon weekend is over for the me and my family. I think I may have enjoyed the volunteering, and being around friends and family more than running.. But I did get to talk to and see a lot of friends – runners, spectators, and volunteers – on the course. So, it’s a toss up, but having my girls more involved was pretty cool. They’ve already told me that they enjoyed it. The Girls on the Run Pasta Party was a very nice treat as well.

The Covenant Health Knoxville Marathon (CHKM) is tomorrow. This marks two full years that I’ve been running in organized races and the third time that I will participate in this event.
My preparation for the half-marathon has not been quite what I wanted. Pervasive aches and pains have side-lined me for most of March, and at this point I would be extremely lucky to complete the half-marathon in less than two hours. In fact, this may go on record as being one of my worst performances.

Previously in my discussion of how I like to use the ui-router and states for basic layout functionality, I touched on the basic tenants of what I see as prominent in many SPA applications. In this discussion, I’d like to dig a little deeper and illustrate a simplified implementation of a menu navigation system.
In developing a menu navigation system, I initially consider how flexible I need the navigation to be. If users can change states with hopeless abandon, then define your states and use ui-sref and nothing more. If we need more functionality, we need a more robust solution.

Angular’s routing does a lot for us. Whether you’re using ui-router or ngRouter, you get a many powerful mechanisms to determine when your state has changed. There are times, though, that I want a “global state.”
What do I mean by global state?

Today I spent a few hours playing around with Apache Cordova. If you don’t know what that is, it’s basically a set of API’s that let you deploy Web Apps (JavaScript) to a mobile device and then have access to that device’s hardware.
If you’re already writing SPA-type apps, Apache Cordova can be a quick way to deploy your Web App to a mobile device and have it behave just like a native app.

Yes, yes, you’ve probably seen posts regarding creating a modal dialog service before. I’ve been using one for a bit and wanted to share my spin on this concept.
Angular’s ui-bootstrap directives provide a lot of functionality out of the box. Having the $modal providers really make it easy to manage dialogs. While it is easy to create your own service that can create simple OK/Cancel requests, it is also pretty straight forward to create modals that let you pass data back and forth to your calling controller.

In .NET when I’m dealing with WebAPI controllers, I like to secure them. Typically, this is done with an [Authorize] attribute on the controller or the controller’s actions.
One problem that arises with .NET, though, is that a user’s auth token/cookie could be expired because they are inactive for a set amount of time. Imagine that you’ve written a shiny new SPA-type web app and is SOA driven. When the user resumes accessing your site, all of the API end-points will fail until the user logs back in.
