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).

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.
