strip-tracking-params

Remove common tracking query parameters (UTM tags, ad click IDs like gclid and fbclid, email-tracking ids) from a URL, returning a clean one. Runs locally, zero dependencies, nothing stored or sent anywhere.

const stripTrackingParams = require('strip-tracking-params');

stripTrackingParams('https://example.com/page?utm_source=news&id=42&fbclid=abc');
// 'https://example.com/page?id=42'   (functional params like id are kept)

stripTrackingParams('https://shop.com/p?ref=x&gclid=z', { extra: ['ref'] });
// 'https://shop.com/p'

What it removes

A documented default list: utm_*, gclid/gbraid/wbraid/dclid, fbclid, igshid, msclkid, ttclid, yclid, mc_cid/mc_eid, _hsenc, mkt_tok and other common analytics and email trackers. See stripTrackingParams.DEFAULT_PARAMS.

Pass { params: [...] } to replace the list, or { extra: [...] } to add to it.

Honest note: it only strips query parameters. A non-absolute URL is returned unchanged (it cannot be parsed safely without a base), and it does not touch path segments or fragments. It reduces tracking, it does not make a link anonymous.
