Last weekend I had the pleasure of presenting a couple sessions on TypeScript at Boston Code Camp 25, one on my own and one with my good friend and colleague, Bob Goodearl. We've just posted the materials, which may be useful beyond the presentation.
This session covers the basics of the language. I tried to distill the whole thing into a set of code samples, inspired by the old "Got Dot Net" site from days of yore. You can find the Github repo here, including project folders for both Visual Studio Code and Visual Studio 2013.
This session delves into creating AngularJS 1.x applications in TypeScript. I started off with the simple example of a weather "widget". A widget is a small application that runs independently on a page; in this case I used the Widget Wrangler library to place the widget on the page. Because it's small and simple, you can easily see how to set up an Angular controller and service in TypeScript, and how to handle Angular promises.
After that, Bob Goodearl picked it up with a more advanced example that shows a hybrid Angular/ASP.NET MVC application with a WebAPI back-end service. Pointers to his code and the other session materials are here on his web site.
Please check it out and send feedback in the comments; thanks!
