Nuxt Security is a security module designed specifically for Nuxt 3 applications that automatically implements OWASP security patterns and principles through HTTP headers and middleware configuration. The module provides comprehensive security features including security response headers with Content Security Policy (CSP) support for static site generation, request size and rate limiting capabilities, Cross Site Scripting (XSS) validation, and Cross-Origin Resource Sharing (CORS) configuration. Additional security enhancements include hiding the X-Powered-By header, removing console loggers in production, HTTP method restrictions, basic authentication support, and Cross-Site Request Forgery (CSRF) protection. Installation is handled through the Nuxt module system using npx nuxi@latest module add security, which automatically registers route rules and server middlewares globally across the application. Configuration options are managed through the nuxt.config.ts file, allowing developers to customize security settings according to their application requirements. The module includes development tools for generating type stubs and running a development playground for testing security configurations.
