Developer recommends backend error tracking for React apps to balance debugging and privacy

A developer argues that React frontend error tracking should use a backend collector that retains only specific evidence needed to reconstruct user issues. This approach aims to debug problems like broken lessons without collecting full session transcripts, protecting user privacy. The recommended method involves sending a small, predefined set of data including exception fingerprints, stack traces, release information, and timestamps. This bounded data collection prevents accidental transmission of sensitive user information like form data or authorization headers. The system separates error metrics for detecting release health from detailed incident reports needed to debug specific user problems.
