Cursor Directory Overview
Introduction to Cursor Directory
Cursor Directory is a comprehensive resource hub designed to provide developers with a curated collection of rules and guidelines for various programming languages, frameworks, and tools. It aims to enhance coding practices by offering expert insights and best practices for a wide range of technologies.
Key Features
The platform covers a vast array of topics including TypeScript, Python, Next.js, React, Node.js, and many more. Each topic is broken down into detailed rules and principles that guide developers on how to write concise, maintainable, and efficient code. Cursor Directory also emphasizes the importance of following best practices in software development to ensure code quality and performance.
TypeScript Best Practices
Code Style and Structure
TypeScript developers are encouraged to write concise, technical code with accurate examples. Functional and declarative programming patterns are preferred over classes to promote iteration and modularization. Descriptive variable names with auxiliary verbs (e.g., isLoading, hasError) are recommended for clarity.
TypeScript Usage
The use of TypeScript for all code is emphasized, with a preference for interfaces over types. Enums should be avoided in favor of maps for better type safety and flexibility. Functional components with TypeScript interfaces are the standard for React development.
Next.js Development Guidelines
Performance Optimization
Next.js developers are advised to minimize the use of 'use client', 'useEffect', and 'setState' in favor of React Server Components (RSC). Wrapping client components in Suspense with fallback and using dynamic loading for non-critical components are recommended practices to optimize performance.
UI and Styling
The use of Shadcn UI, Radix, and Tailwind for components and styling is encouraged. Implementing responsive design with Tailwind CSS and adopting a mobile-first approach enhances the user experience across different devices.
Python Development with FastAPI
Key Principles
FastAPI developers should write concise, technical responses with accurate Python examples. Functional, declarative programming is preferred, and iteration and modularization are encouraged over code duplication. Descriptive variable names with auxiliary verbs (e.g., is_active, has_permission) are recommended for clarity.
Error Handling and Validation
Prioritizing error handling and edge cases is crucial. Developers should handle errors and edge cases at the beginning of functions, use early returns for error conditions, and avoid unnecessary else statements. Implementing proper error logging and user-friendly error messages is essential for maintaining code reliability.
