v0.0.34

New Audit Rules

1 new rule added to help optimize your site's performance:

Performance

• https://docs.squirrelscan.com/rules/perf/js-file-size - Detects oversized JavaScript files that block the main thread and delay interactivity

Other Improvements

• Overhauled asset size rules - Image, CSS, and PDF size checks now use tiered warn/error thresholds instead of single limits:
  • Images: warn at 200KB, error at 1MB (https://docs.squirrelscan.com/rules/images/image-file-size)
  • CSS: warn at 150KB, error at 500KB (https://docs.squirrelscan.com/rules/perf/css-file-size)
  • JavaScript: warn at 250KB, error at 1MB (https://docs.squirrelscan.com/rules/perf/js-file-size)
  • PDFs: warn at 30MB, error at 60MB (https://docs.squirrelscan.com/rules/crawl/pdf-size)
• Fixed React SSR compatibility - Rules now correctly detect attributes like charset, tabindex, nomodule, colspan, and rowspan regardless of casing — handles React's camelCase SSR output like charSet, tabIndex (https://docs.squirrelscan.com/rules/core/charset). Thanks to https://github.com/EnkiYouTube-ui for reporting https://github.com/squirrelscan/squirrelscan/issues/8!
• Updated Googlebot limits - PDF truncation limit corrected to 60MB (was 64MB) (https://docs.squirrelscan.com/rules/crawl/pdf-size)
