best-practices

To audit web application security and code quality, you can review your code against Lighthouse benchmarks to identify mixed content, weak Content Security Policy, and deprecated APIs, then apply secure coding patterns and efficient resource loading optimizations.

Best practices for secure cookies and HTTPS enforcement involve applying strict Content Security Policies, ensuring all resources load over HTTPS to prevent mixed content, and configuring cookie attributes to prevent unauthorized access and session hijacking vulnerabilities.

A Lighthouse audit improves browser compatibility by checking for proper Doctype declarations, character encoding configurations, and viewport settings, ensuring your web code renders consistently and functions correctly across major browsers.

You can check your HTML code for deprecated APIs and performance issues before deployment by auditing your event handling efficiency, semantic HTML structure, and resource loading patterns to ensure modern web standards adherence.

Mixed content and weak Content Security Policy warnings occur when your web application loads non-HTTPS resources or lacks strict CSP headers, requiring you to enforce HTTPS and define secure resource loading policies to mitigate risks.
