angularjs definitely typed visual studio 2015

Question

I'm trying to get my first angularjs project to work within Visual Studio 2015. Worked fine until I tried to move to Typescript. Installed the DefinitelyTyped projects and get lots of error messages.

Here is how to reproduce it:

• Create an empty ASP.NET 4.5.2 application
• Nuget AngularJS Core 1.4.4
• Nuget AngularJS.TypeScript.DefinitelyTyped 4.1.1 (includes jQuery 0.0.1)
• Add an empty TypeScript file

• Add

  /// <reference path="typings/angularjs/angular.d.ts" />
  

  to that file.

• that's when I get 444 errors, starting with

  Error   TS2411  Property 'find' of type '{ (selector: string): 
  IAugmentedJQuery; (element: any): IAugmentedJQuery; (obj: JQuery): 
  IAugment...' is not assignable to string index type 'HTMLElement'.  
  TypeScript Virtual Projects l:\M\eigene dateien\visual studio 
  2015\Projects\WebApplication3\WebApplication3\Scripts\typings
  \angularjs\angular.d.ts
  

Any idea what I'm doing wrong or how to work around it?

Answer 1

I checked this package and most of the errors seem to come from the jquery.d.ts file, which just looks old. That file still uses "bool" instead of "boolean", which was a breaking change made long ago.

I fixed it by adding "jQuery.Typescript.DefinitelyTyped" to the project, which upgraded the jQuery.d.ts file to a version that parsed properly. As soon as I did that, all of the compiler errors went away.

This seems like a bug in the nuget package authoring. I'll look into opening an issue on github.

Hope that works for you.
