Error tracking for a small web app comes down to four things: catch what breaks, group the repeats, read the stack in your own code, and keep the minute before the crash. How each one works in the browser, what to throw away, and when you need a full monitoring tool.
How session replay works, what it captures, and why pairing it with console and network logs turns vague bug reports into diagnosable ones.
"Cannot reproduce" is not a property of the bug. It is a statement about the difference between two machines. There are only about eight such differences, and each one leaves a distinct fingerprint.
DevTools is open on the wrong machine. Here's how to instrument console, errors, fetch, and XHR so a user's browser can tell you what actually happened — and the traps that make naive implementations break the page they're monitoring.
A tour through every signal the BugDump widget collects, why each one earns its place, and which ones actually solve bugs.
