JavaScript for Line of Business Applications

The sample app is 5 screens and fully functional with security, navigation drawer, and backend service communication. Upon completion, the app enables the user to login, make a selection of a t-shirt and place an order.

Let's talk about how to correctly organize front-end with Knockout.js require.js and TypeScript. The problem If we will read TypeScript handbook we will find a lot information about how to load mod...

React 0.13 has just been released into beta, a release I've been eagerly anticipating! This has been the release where finally they will be supporting ES6 classes to create React components. Fully supported, no messing about and jumping through hoops and hoping that breaking API changes don't drop in and catch you off guard.

TypeScript is a fantastic language that extends JavaScript by providing static typing syntax. Writing TypeScript to utilize AngularJS can be clunky at times, and one pain point for me was in writing directives.

AngularJS expects to be feed a factory function that returns an object that defines parameters and functionality for your directive.

In JavaScript, that looks like this.

This post will be part-commentary, part-resource. My goal is to give you, the reader, a better understanding of how to integrate Flow into your projects and avoid any undocumented pain points.

Flow is centered around a server architecture, which allows for online type checking. So, to start, Flow scans your entire project—or, at least, any files marked with the pragma, as Flow's type checking is opt-in. When you later change a file, Flow can intelligently type check the paths in the code that were affected by this change, rather than rescanning the entire project. This leads to big performance gains.

his month, I'm going to show how to use a Backbone View to display the Customer objects I defined in that column. This time I'll also be showing off some useful features in TypeScript, including the ellipse (…) syntax for defining a method that accepts an indefinite number of parameters and the TypeScript equivalent of a lambda expression.

Backbone is designed with the expectation that you'll put your code that generates the HTML in the View's render method. Once you generate your HTML, you can, from within the View, append your HTML to the element set in the el/$el properties. You can also use the View's setElement method to set the View's el/$el properties to your generated HTML.

A tutorial on getting started with building Windows Store apps using TypeScript. It shows you how to use frameworks you already know, like jQuery and Knockout.

In this tutorial we’re going to build a very simple Windows Store application that uses jQuery and Knockout to get some data from the internet and show this in a GridView. I’ll show you how you create a new project, get all the the TypeScript definitions you need, get data from a web service and bind that to the GridView control. I’m assuming you have at least a little TypeScript knowledge. 

If you’ve got existing ActionScript assets but want to migrate them to another language, what do you do? One possibility is to convert AS3 to TypeScript. They share similar language features, but are different enough that the process isn’t trivial.

AngularJs supports all kinds of simple client-side validation. The simplest is data-ng-required which basically says a UI element must be filled in before the form is valid. I am going to make the the phone input screen have validation.

TypeScript might not be as popular as CoffeeScript, but it seems to be catching on with a highly productive niche of developers that are building interesting open source projects. TypeScript is very much of the new school of Microsoft developers: it embraces Node, open standards, open source, while building on interesting influences from Microsoft Research and .NET.

If you’re excited by technologies like C# 5.0’s asynchronous support and ReactiveUI, then TypeScript will help you to be more productive with JavaScript. There’s even Visual Studio support! If you’re from a JavaScript client-side or server-side background, however, then it might be harder to appreciate why TypeScript is interesting.

The first thing to consider is that TypeScript adopts ideas from ECMAScript 6, while compiling down to ES3. This includes features like classes, modules, and a succinct lambda syntax:

Recently I started playing with SignalR using TypeScript, one of the things that very quickly made it's way into my project is the Hubs.tt T4 template file

Hubs.tt is a "T4 template that creates Typescript type definitions for all your Signalr hubs. If you have C# interface named "I<hubName>Client", a TS interface will be generated for the hub's client too. If you turn on XML documentation in your build, XMLDoc comments will be picked up.
