Introduction
In this tutorial, we will be exploring how to use Fingerprint.js library in a ReactJS application. Fingerprint.js is a library that allows you to uniquely identify a user based on their device and browser attributes. This can be useful for tracking users, personalizing content, and enhancing security.
Setting up the project
First, we need to create a new ReactJS project. You can do this by using the create-react-app command:
npx create-react-app fingerprint-demo
Installing Fingerprint.js
Next, we need to install the Fingerprint.js library. You can do this by running the following command in your project directory:
npm install fingerprintjs2
Using Fingerprint.js in ReactJS
Now that we have the Fingerprint.js library installed, we can start using it in our ReactJS application. Here is an example of how to get the user’s fingerprint:
import Fingerprint2 from 'fingerprintjs2';
class App extends React.Component {
componentDidMount() {
Fingerprint2.get((components) => {
const fingerprint = Fingerprint2.x64hash128(components.map((component) => component.value).join(), 31);
console.log(fingerprint);
});
}
render() {
return (

);
}
}
Conclusion
Using Fingerprint.js in a ReactJS application can be a powerful tool for identifying users and personalizing their experience. By following the steps outlined in this tutorial, you can easily integrate the library into your project and start using it to enhance your application’s functionality.
