If you're reading this, you most probably tried to make a long and/or complex list of items using a ng-repeat directive, and after seeing how it performs in terms of speed, felt like AngularJS failed you.

One of the most frequently asked questions we get is when would Angular be a poor choice to use as a framework. Our default answer is usually when writing games as Angular has it’s own event loop handling (the $digest loop) and games usually require lots of low-level DOM manipulation. This is an inaccurate description as there are manytypes of games where Angular can support. Even games that require heavy DOM manipulation can use the angular framework for the static parts, such as tracking high scores and game menus.

Here are a comparison of technologies adoption, thanks to the "google trends" tool, each comparing :

angularjs tutorial (in red) 
vs 
[techname] tutorial (in blue)

The word "tutorial" help here to avoid noise signal due to ambiguous name (jsf is a too generic acronym), and it also help to detect which technology people will in adopt in the very near future (thus avoiding noise due to maintenance on an old technology).

The date following indicates when AngularJS overrun the [techname] technology. 

Front-end application frameworks have given developers the tools to build client side applications with rich user experiences. Let’s say your application is built with one of these frameworks and you want to notify connected clients that something on the server has changed – how can you do that while keeping a rich user experience? This is wherePusher and angular-pusher come into play.

AngularJS is a modern JavaScript framework that allows creating rich client-side apps in a fast and productive way. It goes without saying that AngularJS is convenient and powerful in working with HTML. However, it doesn’t have ready to use complex UI components yet. In this article we’ll try to partially eliminate this drawback by showing how to add support of dhtmlxScheduler, a Google-like event calendar, for an AngularJS app.

Have you used AngularJs and ran into some performance problems? Using ReactJs rendering becomes much faster. A small examples explains how to use ReactJs for rendering in AngularJs and a comparison is made between native rendering and rendering using ReactJs.

I like AngularJS. I use it when I do some little fun projects and I use it professionally in large Web apps. I tried other frameworks as well, likeBackboneJS and EmberJS, which both are great tools as well. All three of them belong to the class of MVC frameworks (or MVVC whatever you want o call them). But whenever I used any of such a tool I always ran and still run into the same problem: Rendering performance of lists of items. Two way binding or one-way binding makes no real difference. For me BackboneJS had better performance for rendering than AngularJS. Lets put that on the back of two-way binding.

This week we’re going to look at form validation with AngularJS. Angular has several directives that support form field validation, and they’re based on theHTML5 form validators. You can specify that a field is required, a certain size, a certain type, and should match a given pattern.

We should have a VNC server on the machine we want to control. This machine provides interface accessible through the RFB protocol. The proxy in the middle has RFB client, which knows how to talk to the RFB server. The proxy also provides HTTP server, which is responsible for serving static files to the client and also allows communication through socket.io. The last component in our diagram is the “AngularJS VNC client”, which consists few HTML and JavaScript files provided to the browser by the proxy. This is what actually the user of our VNC client sees. He or she use the form provided in the “AngularJS VNC client” in order to enter connection details and connect to the machine he or she wants to control
