问题 I'm using tsd to download definitions from Definitely Typed and compile into a tsd.d.ts file. I haven't been able to build yet, but when I use an import like this: import * as THREE from "three" Visual Studio intellisense is happy. However, this doesn't work for Detector.js (a three.js library for detecting webgl support), with this .d.ts file.

问题 I'm trying to install TypeScript definition files from DefinitelyTyped within a ASP.NET v5 web project in Visual Studio 2015 RC? NuGet packages don't seem to work anymore and TSD hasn't been updated in awhile and I haven't seen a lot of good documentation for it when using it within VS.

阅读更多关于 What to do if a typings (or tsd) is not available?

I was looking over the TypeScript handbook and I can't seem to find the answer. If I am using a library that no typings exist, what are my options? One is to create the typings file, but this I don't really want to do. What are my other options, I seem to remember some kind of 'declare' keyword ? Or maybe something in the tsconfig ? I assume there is a way of declaring this variable (type) globally so every time I use it, it would just work. And I presume there is a way of just declaring it only available in one file. Of course the best way would be to include a typings file but this won't

阅读更多关于 When to use ambient while searching for a type definition?

问题 I'm currently migrating from tsd to typings since it's deprecated. but It's not crystal clear when I need to use --ambient or not when looking for a definition. Also: is it correct to say that the goal of typings, in the longterm, is to completely move away from ambiant declatation from DefintelyTyped and only rely on the typings registry? 回答1: but It's not crystal clear when I need to use --ambient Always Ambient Stuff Stuff that changes the nature of the global environment (e.g. node.d.ts )

阅读更多关于 How should I use @types with TypeScript 2

So far we are used to tsd or (The better version of it) typings But now that TypeScript 2 offers the new @types feature, how should I convert my current project to work with @types? I have tsd.json (typings.json is some cases) with all the dependencies, what are the steps to do the move to TypeScript 2? What are the new best practices? Does @types support specific versions?
