While attempting to set up a unit testing environment that involves MochaJS and BabylonJS, the importing of BabylonJS parts threw two kinds of errors: SyntaxError: Named export 'Camera' not found. for import { Camera } from '@babylonjs/core/Cameras/camera.js'; SyntaxError: Cannot use import s…

Has anybody had any new insights on this topic? If I can contribute something on top of the provided demo case, please let me know!

It looks like you are using a special loader ts-node/esm and I am wondering if you do not need another one to consume es6 import styles from our package in mocha. Did you check with them on Github or their forum ???

@sebavan thanks for the suggestion. I actually tried a couple of things, but it’s just shifting the problem around (read: solving one, opening another) as you can see in the several branches.

After several tries and lots of errors, I went with instant-mocha, which is a bundle that packages all the magic of Babel, Webpack, etc. The tsconfig.json and so on are provided. But I just worked around the is…

i’ll download the code tomorrow and see if I can understand the issue better

Hi there! I’m facing the same problems as @fjk . We’re working on a TS project using Webpack & BabylonJS and are a little stuck on making our code testable as importing certain classes from BabylonJS always breaks the tests with different errors. We’re not “bound” to a specific testing framework A…
