JavaScript for Line of Business Applications

Developing SPA application can be extremely exciting, but we should always stay focused on securing all the app’s possible leaks.

Managing user authentication via RIA (Rich Interface Applications) is similar to standard web Client Server Application. Usually, in Standard web apps the authentications is fully managed by the used framework (Laravel Auth, Spring Security …) and it’s pretty simple.

RIA apps uses XHR requests to retrieve data from the server via REST services, it can’t manage authentication exceptions, because the tokens verification are made server side.
In our case we will be developing a REST API that should use the Framework Authentication features and manage Authentication issues (disconnects, session expiry, hacks, etc …) and redirect the user to the login form.

Given, the attention that Web Components and Polymer.js have been getting lately, I felt this was a good opportunity to demonstrate some of the exciting new specifications that are making their way to modern browsers. For the sake of this tutorial, I'll be using and providing screenshots of Google Chrome, but it should be worth your time to explore the status of each of the specifications in other modern browsers as well.

In this tutorial, we will take a look at the HTML5 specs mentioned above in detail. Then, we will explore Polymer.js and build out an example application.

One of the most common questions I see on StackOverflow regarding Angular, are questions involving the creation of AJAX-based angular services using $http. Commonly the pattern used is very reminiscent of JQuery, where there's a method with a callback when the data is received.

In Angular, there is a service called $q. It is a deferred/promise implementation built off of Q by Kristopher Kowal.

Promises get special treatment in Angular however, because when a promise is resolved, Angular will trigger a digest, and any scope properties that contain a promise will be evaluated for that promise's resolved value. So in code, that means if you return a promise from your service, and put it directly in a scope property, it will asynchronously update that scope property and process the changes.

Building Single Page Applications aka. SPA is something that has become more popular this days. We can find a series of astute client-side JavaScript libraries helping us out to solve the most common tasks. KnockoutJS, AngularJS, DurandalJS and BreezJS are frameworks that we would recommend you to take a closer look into.

All of those frameworks delivers a wide range of functionality to solve time consuming issues such as dependency tracking, binding and associating DOM elements to objects and templating.

In this blogpost we show you how you can publish, subscribe updates via a simple RealtimeMVC controller using XSockets.NET. The controller has a dependency to a simple domain model and EntityFramework.

Both Knockout.js and Backbone.js have their strengths and weaknesses, but together they are amazing! With Knockback.js, you can use the strong ORM provided by Backbone and create dynamic views using Knockout bindings.

Features:
* Localization
* Knockout.js' bindings and automagical update
* Backbone's sleek Model definition
* Dynamic collection sorting
* Two-way string formatting

In this post:

* Specifying a function as string replacement
* Array Equality
* Dynamic Function Creation
* Using Object.prototype.toString for confirming Array
* Knowing when to break the rules

What Is Yeoman? Trick question. It's not a thing. It's this guy: Basically, he wears a top hat, lives in your computer, and waits for you to create. As an example, scaffolding a web application would look something like this: ...

Presenting content on the internet is different from what it was a few years back. Providers are trying to make it as beautiful as possible, they are trying to reach as many users as possible, and most importantly, they are trying to make the experience of consuming content as enjoyable as possible.

This last goal is where JavaScript frameworks come into the process. Using these, providers can publish their content in the most usable form, allowing users to interact with it, to share it, and contribute to it.

At this point say hi to Ember.js. By using it, I am able to provide a great experience for my users. Let us look at this in a bit more detail.

Craig asks "is your website responsive"? He doesn't need to know it works on a mobile device but whether you're using the useful script timers and profiling tools in your developer console.
