javascript - d3-geo-projection es6 imports -

i've started using es6 imports in projects , id import d3-geo-projection in such way can call projections have, in:

var proj = d3.geoaitoff();

and i'd avoid rolling own bundle.

i have tried

import * d3 'd3'; import 'd3-geo-projection';

and tried

import * d3 'd3'; import {geoaitoff} 'd3-geo-projection';

neither results in being able call var proj = d3.geoaitoff();

can advise on how should done?
