@errtap/browser

Browser error tracking for ErrTap — captures unhandled errors, promise rejections, structured logs, and Core Web Vitals.

npm i @errtap/browser

import { init } from '@errtap/browser';

init({
  dsn: 'https://et_…@api.errtap.com', // from your project's settings page
  environment: 'production',
  release: import.meta.env?.VITE_GIT_SHA,
});

init registers window.onerror and unhandledrejection handlers. Manual capture and logs:

import { captureException, captureMessage, logger } from '@errtap/browser';

logger.info('checkout started', { cartSize: 3 });
try {
  await checkout();
} catch (e) {
  captureException(e, { tags: { flow: 'checkout' } });
}

Web vitals

init also measures LCP, INP, CLS, FCP and TTFB (no extra dependency) and sends them in one request when the page is first hidden, to your project's Performance page. The URL is sent without its query string or hash. Opt out or sample:

init({ dsn, vitals: false });          // off
init({ dsn, vitalsSampleRate: 0.1 });  // 10% of page views
