ClientJS is a JavaScript library that provides developers with an easy way to generate browser fingerprints by exposing all the browser data-points. A browser fingerprint is a unique identifier that can be used to track and identify users across different websites and online platforms. ClientJS collects various pieces of information about the user's browser, including the user agent, screen size, color depth, timezone, installed plugins, and many other data-points. All of this information is combined into a hash value that serves as the browser's fingerprint. The use of browser fingerprints has become increasingly popular in recent years as a way to track users without relying on cookies. Cookies can be deleted or blocked by users, whereas browser fingerprints are much harder to alter or fake. This technology is often used for marketing purposes, but it can also be used for security and fraud detection. One of the advantages of using ClientJS is its simplicity. Developers can easily integrate the library into their projects and start generating browser fingerprints right away. The library is also lightweight and fast, so it doesn't add significant overhead to the application. However, it's worth noting that some users may be uncomfortable with the use of browser fingerprints for tracking purposes. As such, it's important for developers to provide clear information to users about what data is being collected and how it will be used.

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=""></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.
