React Native

Using the FingerprintJS Pro React Native library

FingerprintJS Pro React Native is an official open-source library for projects written in React Native for iOS and Android platforms. This library allows developers to use Fingerprint Pro capabilities in the React Native context. All Fingerprint Pro agent capabilities are fully supported.

Example Use Case

Add @fingerprintjs/fingerprintjs-pro-react-native as a dependency to your application via npm or yarn.

npm install @fingerprintjs/fingerprintjs-pro-react-native --save

yarn add @fingerprintjs/fingerprintjs-pro-react-native

Wrap your application (or component) in FingerprintJsProProvider. You can specify multiple configuration options.

// src/index.js
import React from 'react';
import { AppRegistry } from 'react-native';
import { FingerprintJsProProvider } from '@fingerprintjs/fingerprintjs-pro-react-native';
import App from './App';

AppRegistry.registerComponent(
  'AppName',
  <FingerprintJsProProvider
      apiKey="fingerprintjs-pro-public-api-key"
  >
    <App />
  </FingerprintJsProProvider>
);

Use the useVisitorData hook in your components to perform visitor identification and get the data.

// src/App.js
import React, { useEffect } from 'react';
import { useVisitorData } from '@fingerprintjs/fingerprintjs-pro-react-native';

function App() {
  const {
    isLoading,
    error,
    data,
    getData,
  } = useVisitorData();

  useEffect(() => {
    getData();
  }, []);

  if (isLoading) {
    return <div>Loading...</div>;
  }
  if (error) {
    return <div>An error occured: {error.message}</div>;
  }

  if (!data) {
   return null
    }
  
  // perform some logic based on the visitor data
  return (
    <div>
      Visitor id is {data.visitorId}
    </div>
  );
}

export default App;
