Guide on setting up global typing for AngularJS in your project

I have been working on a project that initially used the deprecated typings method for incorporating Typescript definitions. I now want to transition to using the @types method instead.

Currently, we have a typings.json file located in the root of the project with the following content:

{
  "globalDependencies": {
    "angular": "registry:dt/angular#1.5.0+20161101124950",
    "angular-cookies": "registry:dt/angular-cookies#1.4.0+20160317120654",
    "angular-material": "registry:dt/angular-material#1.1.0-rc5.0+20161208205836",
    "angular-resource": "registry:dt/angular-resource#1.5.0+20160914132003",
    "angular-translate": "registry:dt/angular-translate#2.4.0+20160729132354",
    "d3": "registry:dt/d3#0.0.0+20160907005744",
    "jquery": "registry:dt/jquery#1.10.0+20160929162922",
    "lodash": "registry:dt/lodash#4.14.0+20161110215204",
    "moment": "registry:dt/moment#2.11.1+20161010105546",
    "require": "registry:dt/require#2.1.20+20160919185614"
  },
  "resolution": "src/client/typings",
  "dependencies": {
    "angular-local-storage": "registry:dt/angular-local-storage#0.1.5+20160726182927",
    "angular-ui-router": "registry:dt/angular-ui-router#1.1.5+20161222093745",
    "requirejs": "registry:npm/requirejs#2.2.0+20160319062357"
  }
}

These dependencies are currently installed as globals and are located in a src/client/typings folder within our directory structure.

I have noticed that there is an @types folder under my node_modules which includes some of the typings mentioned in the typings.json file.

Within our tsconfig.json file, we have an 'include' configuration section:

"include": [
        "./typings/index.d.ts",
        "./app/**/*.module.ts",
        "./app/**/*.run.ts",
         "./app/**/*.routes.ts",
        "./app/**/*.enum.ts",
        "./app/**/*.controller.ts",
        "./app/**/*.model.ts",
        "./app/**/*.directive.ts",
        "./app/**/*.filter.ts",
        "./app/**/*.service.ts",
        "./app/interfaces/**/*.ts"
    ],

To ensure that older typings not present in the @types folders are not being pulled in, I have commented out the ./typings/index.d.ts.

However, upon examining a .ts file containing AngularJS code, I have observed that the angular object is no longer resolving:

https://i.sstatic.net/e4Bjv.png

After researching, it seems I can resolve this issue by adding an import statement to the file (e.g.

import * as angular from 'angular'
). But this would require me to add these imports to every .ts file with Angular code.

Is there a recommended way to make the angular reference global in my project, or should I continue with the practice of adding individual imports where necessary?

Thank you

Answer №1

To streamline your project, create a shared .ts file within the 'Typings' directory and include all necessary references in that file as shown below.

https://example.com/image.png

Once you have done this, simply reference the common .ts file in all locations where these references are needed, like so:

/// <reference path="../../typings/common.d.ts" />
