This script is a core component of PostHog's survey functionality, designed to enable dynamic deployment and interaction with surveys on a website or within a web application. Upon integration, it allows site administrators to define and target specific user segments with various survey types, such as NPS, multiple-choice, or open-ended questions. The script communicates with the PostHog backend to fetch survey definitions, render the survey user interface (e.g., as pop-ups, banners, or embedded elements), and capture user responses. It handles client-side logic for displaying surveys, managing their state (e.g., preventing repeat displays to the same user), and securely transmitting collected data back to PostHog for analytics and reporting. This capability empowers businesses to gather direct qualitative insights, understand user satisfaction, and collect actionable feedback for product improvement.
