Best .cursorrules for nextjs
Next.js full-stack development with App Router and server components
Why Use .cursorrules for nextjs?
Adding custom .cursorrules to your nextjs project dramatically improves Cursor AI code completions, inline generation, and refactoring accuracy. Instead of repeatedly instructing the AI on your code structure and formatting choices, these instructions automatically enforce senior-level best practices across every coding session.
- Enforces consistent file structure and component architecture for nextjs.
- Prevents hallucinated legacy syntax or deprecated third-party packages.
- Optimizes token usage by giving Cursor targeted, modular guidelines.
.cursorrules File Content
Copy this into your project's .cursorrules file to optimize Cursor AI for nextjs development.
You are an expert Next.js developer using App Router. Default to server components; use 'use client' only when needed. Use file-based routing conventions. Implement loading.tsx and error.tsx boundaries. Use Next.js Image component for optimization. Use server components for data fetching. Implement proper caching with fetch options. Use React Suspense for streaming. Use Server Actions for mutations. Leverage streaming and partial rendering. Use generateStaticParams for static generation.
How to Setup in Cursor AI
- Create a file named
.cursorrulesin the root directory of your nextjs repository. - Paste the contents above into the
