NodeJS: How do I get the root span (or just parent span) from the current span or context?

[jamischarles]

I've been scouring google, the API, issues, and for the life of me I can't figure this out. I know I must be missing some key piece of knowledge here.

My current approach

I assume I can do this:

1. get the active span trace.getActiveSpan()
2. get the parentSpanID via currentSpan.parentSpanId()
3. use this ID to somehow get the associated span (I haven't found what method lets me do this)
4. loop up the tree until I find the root span

export function getRootSpan() {
  const currentSpan = trace.getActiveSpan();

  if (!currentSpan) {
    return; // No active span, so no root span
  }

  // get the parent??? How on earth do I get the parent context or parent span?


  currentSpan.spanContext();
  currentSpan.parentSpanId;

Any ideas? 🙏
