Visual Studio Code is alerting users that it cannot locate the namespace for types specified in *.d.ts files

Upon using the gulp-angular Yeoman generator with TypeScript as the language, I successfully created a new project. Running the Gulp build process and opening the page in a web browser went smoothly, except for a minor adjustment needed in the tsd.json file. Specifically, I had to change ref: "master" to ref: "1.4.1". The commands executed were:

yo gulp-angular
vim tsd.json
gulp
gulp serve
code .

Subsequently, I accessed the project in Visual Studio Code.

Visual Studio Code flagged issues such as the inability to locate the 'ng' namespace whenever AngularJS data types were used, along with similar problems related to MomentJS and other typings from *.d.ts files.

The content of the project's tsd.json is as follows:

{
  "version": "v4",
  "repo": "borisyankov/DefinitelyTyped",
  "ref": "1.4.1",
  "path": ".tmp/typings",
  "bundle": ".tmp/typings/tsd.d.ts"
}

The .tmp/typings folder contains the following files:

angular-ui-router/angular-ui-router.d.ts
angularjs/angular-animate.d.ts
angularjs/angular-cookies.d.ts
angularjs/angular-mocks.d.ts
angularjs/angular-resource.d.ts
angularjs/angular-sanitize.d.ts
angularjs/angular.d.ts
jquery/jquery.d.ts
moment/moment-node.d.ts
moment/moment.d.ts
toastr/toastr.d.ts
tsd.d.ts

For example, here is part of the navbar.directive.ts source file where Visual Studio Code shows errors:

module editorTs {
  'use strict';

  /** @ngInject */
  export function acmeNavbar(): ng.IDirective {

    return {
      restrict: 'E',
      scope: {
        creationDate: '='
      },
      templateUrl: 'app/components/navbar/navbar.html',
      controller: NavbarController,
      controllerAs: 'vm',
      bindToController: true
    };

  }

  /** @ngInject */
  class NavbarController {
    public relativeDate: string;

    constructor(moment: moment.MomentStatic) {
      this.relativeDate = moment(1444135396045).fromNow();
    }
  }
}

In this code snippet, Visual Studio Code highlights issues with the 'ng.IDirective' and 'moment.MomentStatic' types being unidentified namespaces.

edit:

To resolve these problems, explicitly referencing the type definition files at the beginning of navbar.directive.ts eliminates the errors:

/// <reference path="../../../../.tmp/typings/angularjs/angular.d.ts"/>
/// <reference path="../../../../.tmp/typings/moment/moment.d.ts"/>

It's worth noting that these files are already referenced in .tmp/tsd.d.ts as shown below:

/// <reference path="angular-ui-router/angular-ui-router.d.ts" />
/// <reference path="angularjs/angular-animate.d.ts" />
/// <reference path="angularjs/angular-cookies.d.ts" />
/// <reference path="angularjs/angular-mocks.d.ts" />
/// <reference path="angularjs/angular-resource.d.ts" />
/// <reference path="angularjs/angular-sanitize.d.ts" />
/// <reference path="angularjs/angular.d.ts" />
/// <reference path="jquery/jquery.d.ts" />
/// <reference path="moment/moment-node.d.ts" />
/// <reference path="moment/moment.d.ts" />
/// <reference path="toastr/toastr.d.ts" />

Hence, there should be no requirement to explicitly reference the files again.

Answer №1

After including a tsconfig.json in the main directory of my VS Code project, the problem I was facing got resolved. Additionally, I had to restart VS code for the changes to take effect. Below is what I included in the file:

{
    "compilerOptions": {
        "target": "es5",
        "module": "commonjs",
        "sourceMap": true
    }
}

Answer №2

The namespace 'ng' cannot be found."

Ensure that there are no references to declare module ng in the project. The same applies for moment.

Update

Following the edit made in the question:

To solve the issue, you can explicitly reference the type definition files by adding the following at the top of navbar.directive.ts file.

Please consider using a tsconfig.json: https://basarat.gitbooks.io/typescript/content/docs/project/compilation-context.html

Answer №3

While glancing through the code, I stumbled upon something hidden away in a secretive spot. It appears to have been intentionally positioned there to prevent any potential type errors. It seems that vscode came across this and decided to redefine the overarching 'angular' variable as of type 'any'.

var angular = window['angular'];

Answer №4

Facing a similar issue myself, it seems typings removed the initial definition file that mentioned the "ng" import.

To resolve this, insert the following line back into your angular/index.d.ts file:


// Alias angular as ng
import ng = angular;

Alternatively, consider moving this line to a separate ng.d.ts file to prevent it from getting overwritten by typings in the future.
