Package Exports
- @fingerprintjs/fingerprintjs-pro
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@fingerprintjs/fingerprintjs-pro) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme

<script>
function onFingerprintJSLoad(fpAgent) {
// The FingerprintJS agent is ready. Get a visitor identifier when you'd like to.
fpAgent.get().then(result => {
// This is the visitor identifier:
const visitorId = result.visitorId;
console.log(visitorId);
});
}
</script>
<script
async src="https://cdn.jsdelivr.net/npm/@fingerprintjs/fingerprintjs-pro@3/dist/fp.min.js"
onload="FingerprintJS.load({ token: 'your-pro-key' }).then(onFingerprintJSLoad)"
></script>We recommend to upload the JS script to your server because AdBlock and other browser extensions can block the public script URL.
Alternatively you can install from NPM to use with Webpack/Rollup/Browserify
npm i @fingerprintjs/fingerprintjs-pro
# or
yarn add @fingerprintjs/fingerprintjs-proimport FingerprintJS from '@fingerprintjs/fingerprintjs-pro';
(async () => {
// We recommend to call `load` at application startup.
const fpAgent = await FingerprintJS.load({ token: 'your-pro-key' });
// The FingerprintJS agent is ready. Get a visitor identifier when you'd like to.
const result = await fpAgent.get();
// This is the visitor identifier:
const visitorId = result.visitorId;
console.log(visitorId);
})();
