npm download-data warning: The npm downloads API reported suspected registry-wide zero days (2026-10-30, 2026-10-31). Trailing-week download totals on this page may be understated, not evidence of falling demand. EcosystemPulse excludes unreliable dates from momentum calculations and does not invent missing counts.
