Problem

When I was trying to use heremaps typings in a typescript file in my Angular project

import { H } from 'heremaps'

I got this issue

TS2306: File '<project-path>/node_modules/@types/heremaps/index.d.ts' is not a module.

It is because heremaps is a browser library, but I'm using moduleResolution: "node" in my tsconfig.json.

Solution

The solution is to add heremaps to types field in tsconfig.json

"types": ["heremaps"]

alternative solution is to add this below at the top of the Typescript file

/// <reference types="heremaps" />
