Product analytics for websites. No cookies, no fingerprinting, no personal data.

npm install @analyticstrend/web

import { init } from "@analyticstrend/web";

const analytics = init({ writeKey: "wk_your_key_here" });

analytics.track("page_view");

init sends anything left over from a previous visit, and flushes again as the page is leaving.

Single-page applications need one more line. init runs once per document load, so client-side navigation fires nothing and your page views count first loads only. Track route changes yourself.

What is captured

From 0.2.0 the SDK adds a few properties of its own, so that traffic sources and page flow work without your wiring anything up:

| Property | From | | --- | --- | | $referrer | the referring site's hostname, when it is not your own | | $utm_source, $utm_medium, $utm_campaign, $utm_content, $utm_term | the landing URL | | $ref | the ref or source parameter | | $click_id | the name of a gclid, msclkid or fbclid parameter, never its value | | $path | the current path | | $from_path | the previous path, on page views |

Only those parameter names are read. The rest of the query string is never looked at, which matters because query strings routinely carry email addresses and one-time tokens.

To turn it off:

const analytics = init({ writeKey: "wk_your_key_here", autoCapture: false });
