The bug nobody can find, because nobody wrote it down
Vibe-coded apps generate code for the happy path — never code that records what happened when things go wrong.
The app breaks. A user reports "it just stopped working." When? Doing what? What error? You check the logs and there aren't any — no timestamps, no breadcrumbs, no trace of the request that failed. Now you're debugging blind: sprinkling console.log after the fact, trying to reproduce a bug you never actually witnessed. In production, the "sometimes, for some users" bug is unfindable — there's no evidence it even happened.
Production-ready logging isn't a nice-to-have bolted on later. It's infrastructure you can't retrofit onto a crisis.
Two checks from this doctrine
Real value, not a teaser — two of the 4 checks in full. The rest are in the one-pager.
console.log text nobody can search.debug for development, info for normal operations, error for things that break. Dumping everything into one stream is the same as logging nothing.You can't fix what you can't see — and you can't see what you never recorded.
