Thanks for the issue/PR @jedwards1211!

Changing the project to be type: module means a bunch of build scripts and configs need to be updated to use ESM (thus all the CI failures).

I'm actually going to close this PR because I have a similar PR (#421) that will resolve this exact issue. I was working on it a few weeks back and then got pulled to work on something different –– but I'm a bit further along on updating everything to be ESM compatible so I'll continue finishing that in my branch.

Awesome, thanks! I should have known it wouldn't be as simple as changing package.json, I hadn't gotten around to looking at the build status
