@types/googlemaps/index.d.ts' is not a module

Question

I want to use the Google Maps API with my Angular project, so I used these two commands to install npm packages:

npm install @agm/core --save-dev
npm install         


        

Answer 1

Thanks to this documentation link : https://www.typescriptlang.org/docs/handbook/triple-slash-directives.html

[Angular 6+] You only have to add this line at the beginning (meaning line 1, with nothing before) of your Typescript file :

/// 

[Angular 5-] You only have to add this line anywhere in your Typescript file imports :

import {} from "googlemaps";

Thanks to the answer below, you may also need to add a file /index.d.ts containing (didn't need it though in my case) :

declare module 'googlemaps';
