Client-side SDKs

This feature is available in the observability plugin for the following client-side SDKs:

JavaScript

The observability plugin provides two options for starting new spans:

  • startSpan() ends the span automatically after the callback function completes, whether it returns normally or throws an error
  • startManualSpan() ends the span when you call span.end()

To start a new span:

1// This span ends automatically after the callback completes
2LDObserve.startSpan('fetchData', (span) => {
3  // Your code here
4});

To learn more, read startSpan and startManualSpan.
