Observability: source-map handling
Source maps connect minified production code back to original source so error stacks are readable.
"I get unreadable stack traces from production — source maps should make errors useful, not leak secrets."
Source-map handling means generating accurate .map files, uploading them to your error-reporting service, and protecting them so only trusted systems can access full source code while still enabling readable stack traces.
