best-practices

To audit web application security and code quality, review HTTPS enforcement, Content Security Policy implementation, and dependency vulnerabilities. This process identifies mixed content, weak CSP, and deprecated APIs to enhance overall robustness and maintainability.

Content Security Policy implementation mitigates common web vulnerabilities by restricting resource loading and execution. It serves as a critical security layer that prevents cross-site scripting and data injection attacks when properly configured in web applications.

To ensure browser compatibility, verify proper doctype, character encoding, and viewport meta tags. Use feature detection instead of browser detection and avoid deprecated APIs to guarantee code works across different browsers.

Yes, you can check for vulnerable dependencies before merging a new feature branch by running a dependency vulnerability audit. This verifies that your project meets security requirements and identifies outdated or compromised packages.

The best way to enforce HTTPS and fix mixed content is to audit your application for insecure resource loading. Identifying and upgrading HTTP requests to HTTPS ensures all content is served securely and prevents protocol downgrade attacks.

You need feature detection when deprecated APIs are removed from modern browsers. Checking for feature availability before usage ensures your code maintains compatibility and prevents runtime errors across different browser environments.
