I am not familiar with this in Node.js, but while looking into what this is, I ran into this: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBuffer#security_requirements
Does this affect the usability of this in Node.js? Or is this an issue that is only relevant to code running in a browser?
