Add this behavior to Babel

[robdodson]

I spoke with @hzoo at the recent Chrome Dev Summit afterparty about this issue, and we discussed updating the behavior in Babel to call Reflect.construct when extending exotic things like HTMLElement.

I was wondering if the maintainers of this project would be interested in helping put together a PR to explore updating Babel's behavior?

FWIW, I strongly support this as a way to fix facebook/create-react-app#3225

It may just be me but, I've never actually been able to get this plugin to work.

[robdodson]

@treshugart I put together a simple vanilla element and example and it seems to be working OK. Do you happen to have a reproducible test case where it breaks?

Would love to deprecate this repository if this feature is upstreamed.

is anyone familiar enough with the Babel codebase to do the upstreaming work...? 😁

Can do a call to go over things if it's helpful. babel/babel#4480 (comment) some people are really excited for this kind of thing + https://github.com/WebReflection/babel-plugin-transform-builtin-classes

Ok @nicolo-ribaudo started a PR so maybe everyone can help review if it covers the same behavior as this plugin. babel/babel#7020

Hey @robdodson, I think I was just being a dummy. I was using it on the consuming end as opposed to building Skate with it (IIRC). See comment here. Looks like there's plans for this to go into Skate as well.

Hi everyone,
Can someone confirm if the behavior of this plugin is covered by babel/babel#7020 or not?
I don't want to block that PR on this, but I can look to port this plugin in @babel/plugin-transform-classes if the other Babel team members agree.
