ClientJS

How to use ClientJS

ClientJS is a powerful JavaScript library that can be used to generate browser fingerprints and expose various data-points about the user's browser. In this guide, we'll walk through how to use ClientJS in your web application.

First, you'll need to include the ClientJS library in your web page's HTML. You can do this by adding the following code to your HTML file:

<script src="https://cdnjs.cloudflare.com/ajax/libs/clientjs/0.1.11/client.min.js"></script>

This will load the ClientJS library from a CDN and make it available for use in your web page.

Next, you'll need to create an instance of the ClientJS object. You can do this by adding the following code to your JavaScript file:

var client = new ClientJS();

Once you have a ClientJS object, you can start using its methods to generate browser fingerprints and collect data-points. Here are some examples of how to use the ClientJS object:

// Get the user's browser name
var browserName = client.getBrowserName();

// Get the user's browser version
var browserVersion = client.getBrowserVersion();

// Get the user's operating system
var osName = client.getOSName();

// Get the user's screen resolution
var resolution = client.getScreenResolution();

// Get the user's timezone offset
var timezoneOffset = client.getTimeZoneOffset();

// Get the user's language preferences
var language = client.getLanguage();

// Get the user's IP address (requires a server-side API)
client.getIP(function(ip) {
  console.log(ip);
});

// Generate a browser fingerprint
var fingerprint = client.getFingerprint();

These methods will allow you to gather data about the user's browser, operating system, screen resolution, language preferences, and more. Note that some methods may require additional permissions (such as accessing the user's IP address), and may not be available in all browsers.

Finally, it's important to remember that browser fingerprints can be used for tracking purposes, so you should use them responsibly and with the user's consent. If you're using ClientJS to collect data for analytics or advertising purposes, you should make sure that your privacy policy clearly explains how this data will be used and give users the option to opt out.

In summary, using ClientJS is a straightforward way to generate browser fingerprints and collect data-points about the user's browser. By following these steps, you can easily integrate ClientJS into your web application and start gathering valuable information about your users.
