Provide noscript fallback content
Users with JavaScript disabled, blocked by corporate firewalls, or with failed script loads see blank pages without proper noscript fallbacks.
Quick Reference
- Add with helpful message for JS-dependent features
- Provide alternative content, not just 'Enable JavaScript'
- Use for critical features: analytics fallback, lazy-loaded images
- Consider progressive enhancement: content works without JS
- Important content should be present in the initial HTML, not fetched only after hydration
Check
Verify that this page provides appropriate noscript fallbacks for users with JavaScript disabled or unavailable, ensuring core functionality remains accessible. Confirm important content exists in the initial HTML and is not blocked on hydration.
Fix
Add noscript elements with alternative content or functionality for critical features that depend on JavaScript. Replace UA-sniffed behavior with feature detection and make sure the server-rendered HTML already contains the important content and pagination paths.
