How does one add a typing to typings.json for Typescript in Visual Studio 2015?

Question

I have to ask because this is driving me crazy. I see the npm way of installing typings on Google, but Angular2's tutorial has one add a typings.json file then it added the typings folder and downloaded d.ts files from DefinitelyTyped automatically. I tried this with jquery but it didn't download. I also tried rebuilding the project, which I would expect the package.json to include the commands to add additional typings.

Here's my scripts from the package.json file:

"scripts": {
  "start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\" ",
  "tsc": "tsc",
  "tsc:w": "tsc -w",
  "lite": "lite-server",
  "typings": "typings",
  "postinstall": "typings install"
}

Here's the typings.json file I tried. es6-shim and jasmine downloaded.

{  "ambientDependencies": {
   "es6-shim": "github:DefinitelyTyped/DefinitelyTyped/es6-shim/es6-shim.d.ts#7de6c3dd94feaeb21f20054b9f30d5dabc5efabd",
   "jasmine": "github:DefinitelyTyped/DefinitelyTyped/jasmine/jasmine.d.ts#7de6c3dd94feaeb21f20054b9f30d5dabc5efabd",
   "jquery": "github:DefinitelyTyped/DefinitelyTyped/jquery/jquery.d.ts#7de6c3dd94feaeb21f20054b9f30d5dabc5efabd"
}}

It's probably something simple like not having what appears to be a checksum after the hashtag. Where would I find the correct checksum, or what command do I need to add to package.json to retrieve the typings upon compile, or what am I doing wrong?

Here's another example of adding a line to the typings.json file and then it installs the d.ts files for you. Scroll down until you see Manual Typings

Solution 1

1. Make sure you have npm installed
2. Open up your console of choice (e.g. command prompt or powershell)
3. Navigate to your project folder

Using only npm (TypeScript 2 and later):

4. npm install --save @types/jquery

   Done: See this for more info.

Using typings (Typescript before v.2):

4. Make sure you have typings installed, if not run npm install typings --global

5. Write typings install dt~jquery --save --global

   This should update your typings.json file and download the definition files.

   In the above example for typings, 'dt~' means that it should look for jquery in the DefinitelyTyped repository, the default is 'npm'. The syntax has changed slightly from version 0.x to 1.0, the flag --global was previously --ambient.

Solution 2

I found that opening and resaving package.json once the typings.json file had been created triggered the typings to pull down. This is my current typings file:

{
    "ambientDependencies": {
        "es6-shim": "github:DefinitelyTyped/DefinitelyTyped/es6-shim/es6-shim.d.ts#7de6c3dd94feaeb21f20054b9f30d5dabc5efabd",
        "jasmine": "github:DefinitelyTyped/DefinitelyTyped/jasmine/jasmine.d.ts#7de6c3dd94feaeb21f20054b9f30d5dabc5efabd"
  }
}
