npm install @leracherry/[email protected]

Usage

import { init } from '@leracherry/tracelens-browser';

const stop = init({
  app: 'dashboard',

  endpoint: 'http://127.0.0.1:4173/__tracelens',
});

// Await during application teardown when possible.
await stop();

Captures interactions, Web Vitals, long frames, fetch/XHR timings, and custom spans. Browser support varies. URL queries and fragments are stripped by default; IDs and aria-labels require opt-in. Review explicit names and metadata for sensitive data. Shutdown restores patched APIs and drains queued batches; it rejects on persistent delivery failure so the caller can retry while the page remains alive.
