DIY Session Replay - How tools like Sentry and Posthog Work

About This Event

DenverScript is hosting an evening meetup focused on how session replay tools like Sentry, PostHog, and Pendo work under the hood. Sean Beard will walk through the engineering behind recording browser state, tracking DOM mutations with MutationObserver, and replaying sessions in an isolated iframe, with a demo of a working proof-of-concept. Attendees can expect networking, JS news, a short talk, food and drinks, and a recorded presentation that will be uploaded to YouTube after the event.
