intellisense and code complete for DefinitelyTyped (TypeScript type definitions) on WebStorm IDE

Question

How can I get WebStorm IDE to give me code completion for libraries that I've downloaded.

As you can see angularjs-DefinitelyTyped and jQuery-DefinitelyTyped have been downloaded.

Now I believe that I have to reference the definition file in my .ts files.

But, where WebStorm saves the definition files so I can reference them in my code?

Thank you!

Answer 1

As basarat says in his answer, you need to include the definitions manually. The easiest way to do this is with tsd . Once installed ( npm install -g tsd ), navigate to the directory you want to hold the typings, and install definition files (such as angular, in the following example) like this:

tsd query angular --action install

or, better yet:

tsd init
tsd query angular --save --action install

Note that you can do all this within Webstorm (alt-F12 opens a terminal window).

Answer 2

That dialog is for JavaScript scope, not TypeScript scope (eg see mocha demo http://youtu.be/4mKiGkokyx8?t=1m19s ). That is, Webstorm is using TypeScript definitions to give intellisence for JavaScript.

For TypeScript itself you need to include the definitions into your project manually ( https://github.com/borisyankov/DefinitelyTyped/blob/master/angularjs/angular.d.ts ) and reference them like you always have.

On Webstorm for mac

Preferences->Languages&Frameworks->Typescript

Use tsconfig.json should be checked and you should create a tsconfig.json file which contains

{
  "compilerOptions": {
    "module": "commonjs",
    "target": "es5",
    "sourceMap": true
  },
  "exclude": [
    "node_modules"
  ]
}
