What are those lines for ? I think it is not required for @babel/preset-env to work well.

By the way I think it is related to this error parcel-bundler/parcel#2936 ? I've faced it too and can't find a way to fix it... is it the solution ?

Hi @benavern, sorry for the delay.
It is to be able to transpile properly async functions.

Without it, I get this error in the console :

ReferenceError: regeneratorRuntime is not defined

And obviously the code does not work.

Ah ok. I have struggled with this error too but not with async functions. If I remember well this is when using a bundle (generated by parcel) as a dependancy in a project that uses parcel too.
And I don't have any async function in it.
If you wonna help on it: https://github.com/benavern/z-components

I really like this but unfortunately we're having issues with deploying the v1 site, so I'm gonna close this for now as we're mainly focusing on v2 and the docs site for that version and it doesn't seem like we'll be able to fix the deploy...
