awesome lgtm!

@nbsp maybe you can take a look at the way i'm getting the version. Originally I had it importing package.json directly at runtime but that didn't seem to work reliably so I have it now generating a file at build time. I guess ideally the changeset script would generate this file but I read the docs and couldn't find an obvious way to do that.

idea: add the version file to gitignore, generate it on build/release time on the same step it publishes to npm. that way it pulls in the version file at runtime without redundancy.

see how livekit/protocol JS directory doesn't have protobufs, but the npm package does.

@nbsp yeah good idea - that seems to work fine and will prevent weird local churn.
