vantmetry

vantmetry

Lightweight browser error tracking. Captures JavaScript errors, console errors, and unhandled promise rejections. Uses WebTransport with sendBeacon fallback so error delivery does not block page unload.

Install

npm i vantmetry

Or use the CDN script tag. See vantmetry.com/docs.

Quick start

import { init } from 'vantmetry';

init({ publicKey: 'vpk_your_key' });

That's it. Errors are auto-captured from that point on. See vantmetry.com/docs for full configuration, React/Next.js integrations, manual logging, and PII masking details.

The full TypeScript source is in the src/ directory of this package and on GitHub.
