@lumen-seo/audit

The lumen site-audit engine: a bounded, robots-respecting crawler, 18 built-in audit rules, a severity scorer, and report assembly.

• Crawler — budgeted frontier (--max-pages), per-host rate limiting, sitemap discovery, URL normalization.
• 18 built-in rules — titles, meta descriptions, H1s, canonicals, lang, viewport, image alt coverage, broken internal links, redirect chains, noindex, status errors, insecure HTTP, mixed content, latency, Open Graph tags.
• Scoring + reports — severity-weighted scores, typed findings, abort-safe partial reports, PII-sanitized output.

import { runSiteAudit } from "@lumen-seo/audit";

Usually consumed through the CLI (npx -y @lumen-seo/cli audit <url>). Ships compiled JavaScript + .d.ts — plain node import, no flags. Rules reference: https://nitishagar.github.io/lumen/docs/rules-reference/
