Description

A comprehensive overview of this resource

This JavaScript resource loads on a webpage to passively monitor user click events. It identifies "dead clicks" by observing when a user clicks an element that does not lead to navigation, form submission, or any other visible dynamic change on the page. By capturing these events, the script helps website owners understand areas where users might be experiencing frustration, encountering broken elements, or misunderstanding the site's interface. The collected data is typically sent to Langfuse's backend for analysis, allowing for quantitative and qualitative insights into user behavior and potential areas for website optimization. The script operates entirely client-side within the user's browser, listening for specific DOM events.
