Fingerprint — Vue
Integrate Fingerprint into a Vue 3 app to identify visitors: register the plugin once at startup,
then ask it for the visitor's visitor_id and a single-use event_id wherever you need it (on
mount, or on an action like login or checkout).
Docs: https://docs.fingerprint.com/docs/vuejs · JS Agent v4: https://docs.fingerprint.com/reference/js-agent-v4
Package
@fingerprint/vue — install the latest version. (Nuxt uses the same package, registered
client-side. For plain HTML or an unsupported framework, use @fingerprint/agent instead.)
Env var
FINGERPRINT_PUBLIC_API_KEY — the public key, safe to ship to the browser.
Bundlers only expose prefixed vars to client code — map the key to the bundler's convention:
- Vite:
VITE_FINGERPRINT_PUBLIC_API_KEY → import.meta.env.VITE_...
- Vue CLI:
VUE_APP_FINGERPRINT_PUBLIC_API_KEY → process.env.VUE_APP_...
Never expose FINGERPRINT_SECRET_API_KEY to the frontend.
Steps
-
Install @fingerprint/vue.
-
Initialize once at the app root. Register FingerprintPlugin with app.use(...), passing
the public key and region (us | eu | ap, matching the workspace). See snippets/plugin.js.
-
Get the identification where you need it. Use the useVisitorData composable. For
identify-on-demand pass { immediate: false } and call getData() on the action you care
about; it returns { visitor_id, event_id, ... }. See snippets/use-visitor-data.vue.
-
Verify it works. Disable your ad blocker, run the dev server, trigger the call, and confirm
a visitor_id is logged in the browser console (or that the event appears on the dashboard
Events page).
Notes
- Region must match the workspace (
us | eu | ap).
- Register the plugin once at the app root; don't re-instantiate per component. Don't block the UI
on identification — handle the composable's
isLoading / error state.
- Production: protect the agent from ad blockers with a custom subdomain or proxy —

- Don't use legacy
@fingerprintjs/fingerprintjs-pro, FingerprintJS.load(), or scriptUrlPattern.
