best-practices

To audit web app security headers and CSP compliance, run a best-practices audit that checks HTTPS, HSTS, Content Security Policy, and secure cookies, returning a prioritized checklist of security fixes using tools like SecurityHeaders.com and Mozilla Observatory.

The best way to improve Lighthouse performance scores for a single-page app is to apply best-practice tuning: avoid blocking scripts, implement efficient event handling, optimize source maps, and manage memory effectively to satisfy Lighthouse recommendations.

To check browser compatibility and replace deprecated APIs in a static site, apply progressive enhancement techniques: validate doctype, charset, and viewport settings, then implement feature detection and polyfills to ensure cross-browser support.

Yes, you can use this to run dependency vulnerability checks on your web application by executing npm audit instructions to identify vulnerable libraries and keep dependencies up to date as part of a comprehensive production readiness audit.

To fix React error boundaries and semantic HTML issues for production readiness, apply code quality and UX best practices by implementing proper error handling patterns, using semantic HTML tags, and completing an audit checklist for production deployment.

You should not rely solely on automated web audit tools for security hardening when dealing with complex application logic, as tools like W3C Validator and Lighthouse provide baseline checks but require manual implementation of secure cookies, CSP rules, and HSTS enforcement.
