Issue

The code works fine in development builds, but when published (in my case with AOT, I didn’t test without), I am getting l.Control.Draw is not a constructor.

Solution

Be prepared. This is uglier than Ted Cruz and Papa John’s bastard baby.

First

Import leaflet and leaflet-draw into your equivalent of vendors.ts:

import 'leaflet';
import 'leaflet-draw';

Second

Wherever you have used these imports in your code, replace it with:

declare const L: any;

If you encounter build errors, you can use @ts-ignore:

// @ts-ignore
drawControl: L.Control.Draw;

Et voila.

F***ing stupid.
