Vanilla TypeScript example

The complete example instruments a named interaction and explicit application span without a framework.

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

init({
  app: 'vanilla-example',
  release: '1.0.0',
  environment: 'development',
  endpoint: 'http://127.0.0.1:4173/__tracelens',
});

mark('example-ready');

document.querySelector('button')?.addEventListener('click', async () => {
  await trace('calculate-report', () => calculateReport());
});

Start Studio first, serve the example from a loopback origin, click Calculate report, and inspect the newest interaction.
