I've been playing around with AngularDart, the up-and-coming Dart web framework from the Angular team. Not only because we have a Dart Flight School event in Espoo this weekend, but also because it's an interesting piece of technology to me as an AngularJS developer: Many of the ideas and features that will eventually ship with AngularJS 2.0 are already in AngularDart today.
In this article I'll talk about a few of the observations I've made about AngularDart, mainly comparing it to AngularJS. For a prior article about similar subjects, do take a look at Victor Savkin's excellent "AngularDart for AngularJS Developers".
Update: A revised version of this is now in the official Angular docs.
There are three different mechanisms for watching a value on an Angular scope: Reference watches, collection watches, and equality watches. The difference between the three is in the depth in which they watch their values.
Choosing the most appropriate watch mechanism is important, not only because the three mechanisms behave differently, but also because they have very different performance characteristics.
This short article describes the differences between the three watch depths.
While the Angular documentation is getting very good, and there's an increasing number of third-party resources, there's really no better way to really learn a technology than to take it apart and see what makes it tick.
In this article series, I'm going to build an implementation of AngularJS from the ground up. As I take you through it step by step, you'll gain a deep understanding of exactly how Angular works.
In this first installment of the series we'll see how Angular scopes work and what things like
$apply actually do. The dirty-checking logic of Angular may seem somewhat magical, but it really isn't, as you'll see.
Pedestal is an interesting beast. It aims to provide tools for building single-page ClojureScript webapps with the simplicity and elegance we've become accustomed to in Clojure. It is also perceived as a difficult technology to master with several new concepts to grasp, some of them quite subtle.
I think there's some truth in both claims. In this post I'll share my experiences with Pedestal so far. It is loosely based on a talk I gave at the ClojuTre event earlier this fall.
