How are the definitions files loaded in typescript
These days everyone use tsconfig.json, either original or atom-flavored (in Atom editor). When using tsconfig.json, you can omit files list and typescript compiler will compile all *.ts files it will find in any subdirectory, including *.d.ts. Excluding files via exclude is on the way, as well as files globbing. If...
What is the use case for supporting “both types of index” (numeric and string) in TypeScript?
I'd be glad to have some code examples demonstrates what they meant. The following is allowed : interface A{ } interface B{ foo: number; } interface Something { [index: string]: A; [index: number]: B; } But this is not: interface A{ foo: number; } interface B{ } interface Something...
Method Put not Allowed in IIS 7.5 using Type Script + Angular Js + Web API Status 405

It is likely that WebDAV is enabled and is interfering with your request. If you aren't using it, you need to get it out of the way so you can use PUT requests for your Web API. You should be able to do this using your web.config file: <system.webServer> /*...
JavaScript map(), undefined property of object from the collection
The most likely answer is that val is a string containing the JSON you see in the console. If it were an object, the console output would look different. It looks like you need to put a JSON.parse in there. You haven't shown the original TypeScript, but in the JavaScript...

How do I access the service provider when registering using typescript class
angularjs,configuration,typescript,service-provider,typescript1.5
Problem is with your registration of provider. Instead of angular.module('apiService').provider('apiService.baseService', BaseServiceProvider); do: angular.module('apiService').provider('BaseService', BaseServiceProvider); and access in the config phase like you do, BaseServiceProvider (postfix word Provider). When injecting the provider instance anywhere else you could just use BaseService. So basically you don't inject with the class name, instead you...

Exception with type definition for random-string module
Your declaration says there is a module named random-string with a function named randomString within it... So your usage should be: console.log(randomString.randomString({ length: 10 })); console.log(randomString.randomString()); If the module does actually supply the function directly, you should adjust your definition to do the same: declare module "random-string" { function randomString(opts?:...

When Using Typescript+angularjs the api result is not displaying in html
You have to be careful with this semantics. In this code: return this.$http.get('facilities.json').success(function(response) { this.result = response; console.log(this.result); }) this is not referring to your test instance, but instead to whatever context the function is running in.
