It acts as a style guide that AI follows when generating or modifying code, ensuring consistency with your codebase conventions. When you place a `.cursorrules` file in your project root, Cursor AI automatically reads it and adheres to the defined: - **Coding conventions** - Language idioms, naming patterns, file organization - **Framework patterns** - Best practices for your specific framework - **Testing requirements** - When and how to write tests - **AI behavior** - How verbose or concise responses should be ## Supported Technologies ### Programming Languages The generator supports **10 programming languages** with language-specific rules: | Language | Key Features | |----------|--------------| | TypeScript | Strict typing, interfaces, modern ES features | | JavaScript | ES6+, modern patterns, clean code | | Python | PEP 8, type hints, Pythonic idioms | | Go | Effective Go patterns, error handling | | Rust | Memory safety, ownership, async patterns | | Java | Enterprise patterns, modern Java features | | C# | .NET conventions, LINQ, async/await | | PHP | PSR standards, modern PHP 8+ | | Ruby | Ruby idioms, convention over configuration | | Swift | Swift style guide, protocol-oriented design | ### Frameworks **25+ frameworks** across all supported languages: - **TypeScript/JavaScript**: Next.js, React, Vue.js, Angular, Svelte, Express.js, NestJS - **Python**: FastAPI, Django, Flask - **Go**: Gin, Echo, Fiber - **Rust**: Actix Web, Rocket, Axum - **Java**: Spring Boot, Quarkus, Micronaut - **C#**: ASP.NET Core, Blazor - **PHP**: Laravel, Symfony - **Ruby**: Ruby on Rails, Sinatra - **Swift**: SwiftUI, UIKit, Vapor ## How to Use 1. **Select your programming language** - Choose from 10 supported languages 2. **Choose your framework** - Options adapt based on your language selection 3. **Configure code style** - Functional, Object-Oriented, or Pragmatic 4. **Set testing approach** - From TDD to no tests 5. **Select AI behavior** - How verbose AI responses should be 6. **Add additional rules** - Toggle optional guidelines 7. **Copy or download** - Get your `.cursorrules` file Place the generated file in your project root directory. --- ## Code Style Options ### Functional Emphasizes pure functions, immutability, and composition. Ideal for React hooks, Redux patterns, and data transformation pipelines. ### Object-Oriented Uses classes, inheritance, and encapsulation. Best for enterprise applications, game development, and complex domain models. ### Pragmatic Mixed approach that uses the best tool for each situation. Most flexible option for real-world projects. --- ## Testing Approaches | Approach | Description | Best For | |----------|-------------|----------| | TDD | Write tests before implementation | High-quality libraries, critical systems | | Comprehensive | High coverage, unit + integration | Production applications | | Moderate | Key paths tested, pragmatic | Most projects | | Minimal | Critical paths only | MVPs, prototypes | | None | No automated tests | Quick experiments | --- ## AI Behavior Modes - **Explicit**: Detailed explanations and step-by-step guidance - **Balanced**: Explains when needed, concise code (recommended) - **Concise**: Code only, minimal commentary - **Teaching**: Educational focus, explains concepts --- ## Additional Rules Toggle optional guidelines to fine-tune AI behavior: - **TypeScript Strict Mode** - Enable strict type checking - **No Console Logs** - Remove console statements - **Prefer Async/Await** - Modern async patterns - **No Mutations** - Immutable data structures - **Error Boundaries** - Comprehensive error handling - **Accessibility First** - WCAG compliance, ARIA labels - **Security First** - OWASP awareness, input validation - **Performance Focused** - Optimize for speed and memory - **SOLID Principles** - Follow SOLID design patterns - **DRY Principle** - Extract repeated code --- ## Frequently Asked Questions ### What is the best .cursorrules configuration for a new project? For most new projects, we recommend: - Your primary language (TypeScript for web, Python for backend/ML) - Your chosen framework - **Functional** or **Pragmatic** code style - **Moderate** testing approach - **Balanced** AI behavior - Enable **strict types** and **early returns** ### Can I use .cursorrules with other AI tools? The `.cursorrules` format is designed for Cursor AI, but the rules are plain text that other AI tools may interpret. The guidelines represent universal best practices that can improve code generation in any AI coding assistant. ### How do generated rules compare to community rules? Our templates are sourced from and enhanced based on the [awesome-cursorrules](https://github.com/PatrickJS/awesome-cursorrules) community collection (35k+ stars) and other high-quality sources. Each template is curated to be actionable, specific, and non-conflicting. ### Why should I use a .cursorrules file? Without a `.cursorrules` file, AI assistants make generic assumptions about your coding preferences. A custom rules file ensures: - Consistent code style across AI-generated code - Framework-specific best practices are followed - Your testing philosophy is respected - AI responses match your preferred verbosity --- ## Try the Generator Ready to create your custom `.cursorrules` file?
