Nextjs Code Review

The nextjs-code-review skill enables AI agents to analyze Next.js application code, identifying potential bugs, performance bottlenecks, and security vulnerabilities within the framework's specific architecture. It provides actionable feedback on component structure, data fetching strategies, and rendering optimizations to ensure high-quality production-ready code.

When to use it

• Before merging pull requests to catch logic errors or anti-patterns in React Server Components.
• During refactoring sessions to optimize image optimization and dynamic/static route configurations.
• When auditing existing codebases for security flaws related to client-side hydration or API routes.
• To validate that new features adhere to Next.js best practices regarding caching and revalidation.

Key capabilities

• Analyzes specific Next.js file structures including app and pages directories.
• Identifies issues with Server Components, Client Components, and the 'use client' directive usage.
• Reviews data fetching methods like fetch, getServerSideProps, and getStaticProps.
• Checks for common performance pitfalls such as unnecessary re-renders or missing metadata exports.

Example prompts

• "Review this Next.js component for potential memory leaks and improper use of the 'use client' directive."
• "Analyze the API route structure in this file for security vulnerabilities and error handling gaps."
• "Identify performance bottlenecks in this page's data fetching strategy and suggest optimizations using React Query or SWR."

Tips & gotchas

Ensure the code provided includes necessary context, such as the full component tree or relevant configuration files like next.config.js, to allow for accurate architectural analysis. This skill is specialized for Next.js; it may not provide meaningful feedback on generic React code outside this framework's ecosystem.
