`imagetools-core` 0.1.0-next.8 uses `||=` which is only available in Node 15 about imagetools

Thanks for the heads up! Typescript should now compile down to es2018, I also fixed the github workflow so unit tests get run in all nodes LTS versions 👍
Vitejs only supports nodes 12.x upwards, so vite-imagetools will too. This means compiling to es2019 should be alright 👍

Should be addressed in release [email protected]([email protected])
(Don't ask me why it's alpha instead of next, I sometimes don't get Lerna 😄)

Update:
The previous version didn't really work so there is a new version published on npm [email protected] that fixes the previous version and also the weird naming!
I consider this issue closed, but if it persists for you feel free to reopen it!
