Getting Started with ES6 – Using Classes

This entry was posted in es6 javascript on by

In a previous post I introduced how ES6 can be transpiled to ES5 using Traceur or Babel. By using transpilers you can write“modern” code and leverage features found in ES6 today while still allowing the code to run in older browsers. In this post I’m going to dive into classes which is one of the shiny new features found in ES6. Getting Started with ES6/ES2015 Classes Classes are the subject of much debate in the JavaScript world with some people loving them and others hating them. I’ve never believed in one world view being right for every situation and think […]

Video: Building a Single-Page App with Angular, TypeScript, Azure Active Directory and Office 365 APIs

This entry was posted in Angular es6 javascript Office365 TypeScript on by

I had the opportunity to speak at the BUILD 2015 conference in San Francisco with my friend Andrew Connell and had a great time! We gave a talk on Angular, TypeScript, Azure AD and Office 365 APIs and I also gave two “Express” talks on TypeScript. It was super fun to meet new people and hang out with everyone at the conference. I even had the opportunity to check out the upcoming HoloLens device which was super cool! I was heading up an elevator to a meeting and a member of the HoloLens team approached me and asked if I […]

The Role of Interfaces in TypeScript

This entry was posted in .NET javascript TypeScript on by

In my last post I talked about how classes and interfaces could be extended in the TypeScript language. By using TypeScript’s extends keyword you can easily create derived classes that inherit functionality from a base class. You can also use the extends keyword to extend existing interfaces and create new ones. In the previous post I showed an example of an ITruckOptions interface that extends IAutoOptions. An example of the interfaces is shown next: interface IAutoOptions { engine: IEngine; basePrice: number; state: string; make: string; model: string; year: number; } interface ITruckOptions extends IAutoOptions { bedLength: string; fourByFour: bool; } […]

Extending Classes and Interfaces using TypeScript

This entry was posted in .NET javascript TypeScript on by

In a previous post I discussed the fundamentals of the TypeScript language and how it can be used to build JavaScript applications. TypeScript is all about strongly-typed variables and function parameters, encapsulation of code, and catching issues upfront as opposed to after the fact to provide more maintainable code bases. One of the great features it offers is the ability to take advantage of inheritance without having to be an expert in JavaScript prototypes, constructors, and other language features (although I certainly recommend learning about those features regardless if you use TypeScript or not). In this post I’ll discuss how […]

Introducing the AngularU Conference

This entry was posted in angularjs conference es6 javascript TypeScript on by

In late 2014 my good friend Peter Kellner approach me with a big idea – an idea that immediately caught my attention. He wanted to explore collaborating on a new conference idea that would highlight Angular and other “hot” Web development topics and wondered if I’d be interested in working with him and another friend of his named Kevin Nilson (who is also a good friend now) on a full-scale conference. I’ve been involved with chairing a lot of conference tracks over the years but never been the driving force behind organizing an entire conference. While the idea was definitely […]

Creating a TypeScript Workflow with Gulp

This entry was posted in .NET angularjs Gulp javascript jQuery TypeScript on by

TypeScript provides a lot of great functionality that lets you leverage many of the features available in ES6 today but how do you get started using it in your favorite editor? If you’re using Visual Studio or WebStorm then TypeScript support can be used directly and everything happens magically without much work on your part. But, if you’re using Sublime Text, Brackets, Atom, or another editor you’ll have to find a plugin to compile .ts files to JavaScript or create your own custom workflow. While several plugins exist to compile TypeScript and even provide code help as you’re writing TypeScript […]

Getting Started with TypeScript – Classes, Types and Interfaces

This entry was posted in Angular HTML5 javascript TypeScript on by

One of the big announcements at ng-conf this week was the collaborative work that the Angular and TypeScript teams have been doing. Angular 2 will leverage TypeScript heavily and you can as well in any type of JavaScript application (client-side or even server-side with Node.js). You can also use ES6 or ES5 with Angular 2 if you decide that TypeScript isn’t for you. Andrew Connell and I gave a talk on TypeScript at ng-conf that you can view here if interested: I’ve been a big fan of TypeScript for many years and decided to update a few previous posts I’ve […]

The first 2 modules of the course are available to view absolutely free so that you can check it out. Here’s an additional […]

Adding Azure Active Directory and OWIN Code into an AngularJS/ASP.NET MVC Application to Handle User Authentication

This entry was posted in .NET ActiveDirectory angularjs Azure Cloud javascript Office365 SPA on by

In a previous post I discussed how to setup the necessary configuration code and assemblies in an AngularJS/ASP.NET MVC application in order to authenticate users against Azure Active Directory (AAD). Once the initial configuration is complete you can write code to redirect users to the AAD login screen to retrieve an ID token. In Part 4 of an article series I’m writing for http://itunity.com I discuss the necessary code that’s required to authenticate a user and retrieve the ID token. Additional topics covered include hooking AAD into the ASP.NET MVC pipeline, creating an Entity Framework token cache, triggering authentication against […]

Adding Azure Active Directory Configuration Code and Assemblies into an AngularJS/ASP.NET MVC Application

This entry was posted in .NET ActiveDirectory angularjs Azure Cloud javascript Office365 SPA on by

In a previous post I discussed the process for registering an application with Azure Active Directory (AAD) so that users can be authenticated. AAD supports a wide range of features that can be used to perform authentication, authorization, and claims-based security tasks. Once an application has been registered with AAD you’ll need to add configuration code into the application’s web.config file, add related NuGet packages, and add custom C# code into the application in order to take advantage of AAD authentication functionality. In Part 3 of an article series I’m writing for http://itunity.com I discuss these tasks and walk-through the […]
