Phaser particle editor and webpack/es6

i’m wondering if anyone has tried the phaser 3 particle editor, available here:
https://github.com/koreezgames/phaser3-particle-editor
along with a webpack project.

the editor exports a .json format sort of configuration object which is loaded fine by phaser, but within the json i have the following:

spacesemitZone":{"source":new Phaser.Geom.Triangle(24,51,41,0,60,51),"type":"random"}}

sublime editor outlines the constructor in red, so i’m pretty sure that the .json file isn’t linking up with phaser, due to the webpack construction. i can’t just import phaser into the json in the normal way, and my particles don’t appear onscreen.

has anybody dealt with this before?
