This script monitors user click events within a web application to identify instances where a click does not result in an expected change or action, commonly referred to as a 'dead click'. It operates by observing the DOM for changes after a click or tracking if an associated event handler was triggered. When a dead click is detected, the script captures relevant context, such as the clicked element, its position, and other interaction details, and transmits this data to the Langfuse backend for analysis. This helps website owners diagnose user experience issues, identify unresponsive UI elements, and improve overall usability. The script runs client-side and is typically integrated as a third-party dependency.
