ng namespace not found

I am currently in the process of converting a simple Angular 1.6 project to TypeScript. I have declared all the necessary typings dependencies and they have been compiled and installed successfully. However, I am encountering a compilation error stating "Cannot find namespace 'ng'" in my service file. The Angular name is also not being recognized.

Here is a screenshot for reference

Here is the content of tsconfig.json:

{
    "files": [
        "app/**/*.ts",
        "app/**/*.js",
        "main.js",
        "renderer.js"
    ],
    "compilerOptions": {
        "target": "es5",
        "module": "commonjs",
        "moduleResolution": "node",
        "sourceMap": true,
        "declaration": false,
        "noImplicitAny": false,
        "allowJs": false,
        "rootDir": ".",
        "typeRoots": ["./typings"] 
    }
}

The contents of typings.json are as follows:

{
  "dependencies": {
    "angular": "registry:dt/angular#1.6.0+20170321201455"
  },
  "globalDependencies": {
    "jquery": "registry:dt/jquery#1.10.0+20170310222111"
  }
}

Lastly, here is an excerpt from the service.ts file:

module Services {

    export interface IMyService {
    }

    export class MyService {

        http: ng.IHttpService;
        location: ng.ILocationService;

        constructor($http: ng.IHttpService, $location: ng.ILocationService) {
            this.http = $http;
            this.location = $location;
        }

    }
}

Answer №1

Perhaps it would be beneficial to update your tsconfig.json file by including the types for Angular like so:

{
    ...
    "compilerOptions":
        ...
        "types": [
            "angular"
        ],
}

If this approach does not yield results, considering that 'typings' is no longer in use, I recommend utilizing npm to install @types/angular:

npm install --save-dev @types/angular

and then reference it in the same manner as depicted above.

Cheers.

Answer №2

To add the necessary npm package, follow these steps:

npm install --save-dev @types/angular

Afterwards, include this line at the top of your .ts file:

import * as angular from "angular"
.

This solution should resolve any errors. Thank you.
