Ideas, tutorials, and updates from our team.
We moved every BugDump portal from bugdump.com/p/acme-store to acme-store.bugdump.com without moving a route file: TanStack Router rewrites the URL on the way in and on the way out. An output rewrite that edits its URL sends links to the wrong host, navigate() can't cross origins, and a wildcard Workers route runs in front of every Custom Domain in the zone.
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.
An embedded widget can read the page's html lang, the visitor's navigator.languages, or what the site tells it. They often disagree. The order we chose for BugDump's widget, why the page goes first, and the small things that broke along the way.
We gave every priority a stable key so integrations could rely on it. That key quietly became the value we sent to clients too — so making priorities editable meant finding nine readers, four switch statements that fail silently, and one assumption that was wrong in the plan.
Your app has a dark mode toggle. The chat bubble, feedback widget, and cookie banner ignore it. Why prefers-color-scheme is the wrong signal for embedded widgets, and the small API that fixes it.
How session replay works, what it captures, and why pairing it with console and network logs turns vague bug reports into diagnosable ones.
Three ways to add a bug report button to any website — script tag, npm package, or programmatic init — with configuration tips and pitfalls.
A third-party widget that ships 450 KB to every visitor has to justify it. Ours couldn't. Here's the measurement, the fix, and the thing about defer that turned out to be wrong.
"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.
Session replay has a reputation problem, most of it earned. Here's how we use it — scoped to a report, redactable by the user, and off with one line.
A tour through every signal the BugDump widget collects, why each one earns its place, and which ones actually solve bugs.
