47 exported functions, zero JSDoc. 12 public APIs, no descriptions. DocCoverage measures documentation coverage and finds every undocumented function before your team pays the price.
Undocumented functions slow onboarding, hide assumptions, and breed bugs. Every missing docstring is a question your teammates will ask on Slack instead of reading the code. DocCoverage finds every gap and gives you a clear path to fix it.
Finds every exported function, class, and method that lacks documentation. Catches the #1 documentation gap in any codebase.
Detects docs missing parameters, return types, or exception descriptions. Partial docs are often worse than no docs at all.
Validates your README has installation, usage, API reference, and contributing sections. No more empty READMEs passing review.
Scans REST and GraphQL endpoint handlers for missing documentation. Every public API deserves a clear description.
Checks that exported types, interfaces, and structs have descriptions. Complex types without docs become tribal knowledge.
Flags stale, misleading, or low-value comments like "TODO" or "fix later." Measures comment quality, not just quantity.
They generate docs. DocCoverage measures coverage.
