use namespace as type in typescript

Question

I have installed type definitions for google maps that declares a namespace like this:

namespace google.maps {   export class Map {     // ...   }    // ... } 

So if i just use the API globally it works beautifully:

const map = new google.maps.Map(); 

For unit testablity I don't want to access the API globally but instead inject it. But it seems I can't type that a variable should by from type google.map

So this doesn't work:

function mapFactory(api: google.maps) {     return new api.Map(); } 

Any solution how to use the namespace as a type?

Try:

function mapFactory(api: typeof google.maps) {     return new api.Map(); }
