How the Health Score Works
Each package is scored across six dimensions with a maximum of 100 points. Publish recency (25pts) rewards packages with recent releases. Download trend (20pts) measures whether adoption is growing or shrinking. GitHub activity (20pts) checks when the last commit was made and whether the repository has been archived. Issues health (15pts) looks at the ratio of open to closed issues. Maintainer count (10pts) flags single-maintainer bus factor risk. Dependencies (10pts) scores packages with fewer transitive dependencies higher.
Grades run from A (85+) through F (below 30). A deprecated or archived package will score very low regardless of its download numbers. That matters because a dependency can still be widely installed while carrying real maintenance or supply-chain risk.
