Live tracing lets you watch a trace fill in while it’s still running—spans show up as they finish, so you can debug long-running workflows without waiting for the root span to end. Live trace updating as spans arrive

​
How to use it

  1. Trigger a run that produces traces.
  2. Open the trace in Laminar.
  3. Keep the trace open—new spans will appear as they’re exported.

​
Reduce delay (development)

Laminar batches spans for performance by default, which can add a small delay between a span ending and it appearing in the UI. For faster updates during development, disable batching: 
import { Laminar } from '@lmnr-ai/lmnr';

Laminar.initialize({
  projectApiKey: process.env.LMNR_PROJECT_API_KEY,
  disableBatch: true,
});
Disabling batching increases export overhead. Keep batching enabled in production, and flush spans explicitly for short-lived processes. See Flushing spans and shutting down.
