FAQ

What did ArcSight find in React Router (packages/react-router)?
React Router (packages/react-router) has 69 modules and an architecture score of 72.9/100.
Why does the React Router (packages/react-router) structure matter?
The React Router (packages/react-router) score is 72.9/100 across 69 modules and 289 edges.
Which file should I inspect first in React Router (packages/react-router)?
Start with lib/router/utils. Run arc impact on that file before the change merges.

Key takeaways

  • •Structural scan reports dependency cycles — inspect impact paths before refactors that cross module boundaries.
  • •High fan-in modules are change-risk zones; run arc explain <path> before refactoring.
  • •Run the full workflow (analyze, hotspots, explain, impact, snapshot, drift) in your repo for deterministic architecture insights.
