README

Enables tracking of users via a favicon tricks in your Laravel project. Even when they are incognito. For educational purposes only.

Installation

  • run composer require julesgraus/favicontracker in the root of your laravel 6+ project.
  • Publish the config file using php artisan vendor:publish --tag=fit in the root of your laravel project.

Usage

When you've installed the package you will have some extra routes. The /fit route can be used to test the package. It will display a page on which you can start the read and write processes. You can also head to /fit/read and /fit/write yourself to programmatically start these processes. In the Verified tracking procedures section you will see what you need to do to track users. At the moment it does not seem to be possible to start a read action first, and then reliable write a tracking id into the favicons cache without closing the browser. Also a delay must be used to iterate over the tracking routes as it takes some time for the browser to start requesting a favicon.
