Cursor Coding Prompts
Last updated: April 2026
After using Cursor daily for over a year, I've learned that prompt quality directly determines whether you get magical results or frustrating hallucinations. Good prompts leverage Cursor's unique codebase awareness—it can read your entire project context, not just the current file. These prompts were crafted through hundreds of hours of real development work and will help you generate production-ready code, debug complex issues, and refactor with confidence. Expect results that feel like pairing with a senior engineer who knows your codebase intimately.
Generate a React component with TypeScript
beginnerCreate a [ComponentName] React component using TypeScript and functional components. Include proper TypeScript interfaces for props, use React hooks for state management if needed, and add comprehensive JSDoc comments. Make it responsive with Tailwind CSS classes and include at least two interactive elements. Export the component as default.Expected Output
A complete React component file with TypeScript interfaces, useState/useEffect hooks, Tailwind classes for styling, interactive buttons/inputs, and thorough JSDoc documentation. The component will be fully typed and ready to import.
Explain this complex function
beginnerAnalyze the function at line [line number] in [filename]. Explain what it does in plain English, identify any potential bugs or edge cases, and suggest improvements for readability. Break down the algorithm step by step and comment on time/space complexity.Expected Output
A clear English explanation of the function's purpose, bullet points about edge cases, specific bug identifications with line numbers, complexity analysis (O notation), and refactoring suggestions with code examples.
Write unit tests for existing code
beginnerGenerate comprehensive unit tests for the [function/component name] in [filename]. Use [Jest/Vitest] with [React Testing Library] if it's a React component. Cover happy paths, edge cases, and error scenarios. Mock external dependencies appropriately and include descriptive test names following AAA pattern (Arrange, Act, Assert).Expected Output
A complete test file with 5-10 test cases, proper mocking setup, clear test descriptions, and assertions that verify both behavior and edge cases. Tests will be organized logically.
Convert JavaScript to TypeScript
beginnerConvert the entire [filename] from JavaScript to TypeScript. Add proper type annotations for all variables, functions, and parameters. Create interfaces/types for complex objects. Fix any implicit 'any' types and add generics where appropriate. Preserve all functionality and comments.Expected Output
A fully typed TypeScript version of the file with no 'any' types, proper interfaces defined at the top, and preserved functionality. Cursor will explain type decisions in comments.
Generate API endpoint boilerplate
beginnerCreate a [GET/POST/PUT/DELETE] API endpoint for [resource name] using [Express/Fastify/NestJS]. Include proper validation with [Joi/Zod], error handling middleware, authentication middleware check, database query with [Prisma/TypeORM], and comprehensive logging. Return appropriate HTTP status codes and standardized response format.Expected Output
A complete route handler with middleware chain, validation, database operations, error handling, and proper response formatting. Includes comments about security considerations.
Debug this error message
beginnerI'm getting this error: '[paste exact error message]' in [filename] at line [line number]. Analyze the error, trace through the relevant code in the codebase, and suggest 3 possible fixes with code examples. Explain why each fix would work and which one you recommend.Expected Output
A diagnosis of the error root cause, 3 specific fix options with code snippets, and a recommended solution with explanation of why it's the best approach.
Refactor complex conditional logic
intermediateRefactor the complex if-else/switch statement starting at line [line number] in [filename]. Use guard clauses, early returns, or strategy pattern to simplify. Extract complex conditions into well-named helper functions. Maintain exact same behavior but improve readability and testability. Show before/after comparison.Expected Output
A refactored version with clearer logic flow, extracted helper functions with descriptive names, and comments explaining the transformation. Includes metrics on reduced complexity.
Implement design pattern for specific problem
intermediateAnalyze the [feature/module name] and recommend which design pattern would be most appropriate (Factory, Observer, Strategy, etc.). Then implement that pattern for the [specific use case] with concrete examples in our codebase. Show how it improves over current implementation.Expected Output
Pattern recommendation with justification, then a complete implementation with interfaces, concrete classes, and usage example. Includes migration path from current code.
Optimize database queries
intermediateAnalyze the database queries in [filename] or related to [feature]. Identify N+1 query problems, missing indexes, or inefficient joins. Rewrite the queries for optimal performance, add appropriate indexes, and implement caching strategy where beneficial. Use [Prisma/TypeORM/raw SQL] as appropriate.Expected Output
Specific performance issues identified with line numbers, optimized queries with explanations, index recommendations, and caching implementation with invalidation logic.
Create comprehensive documentation
intermediateGenerate complete documentation for the [module/feature name]. Include: overview, architecture diagram (in Mermaid format), API reference, usage examples, setup instructions, common pitfalls, and contribution guidelines. Base this on the actual code in [list of files].Expected Output
Well-structured documentation with all requested sections, accurate code examples, Mermaid diagram syntax, and practical guidance based on actual implementation.
Implement authentication flow
intermediateImplement a complete [OAuth/JWT/session-based] authentication system for our [React/Next.js/Vue] frontend and [Node/Express] backend. Include: registration, login, password reset, email verification, role-based permissions, and secure token handling. Use industry best practices for security.Expected Output
Full-stack authentication implementation with frontend components, backend routes, middleware, database schema, and security considerations. Includes environment variable setup.
Set up CI/CD pipeline
intermediateCreate a complete CI/CD pipeline configuration for [GitHub Actions/GitLab CI/Jenkins] for our [type of application]. Include: test running, linting, building, Docker image creation, security scanning, and deployment to [AWS/GCP/Azure]. Add proper environment variable management and rollback procedures.Expected Output
Complete YAML configuration file with multiple jobs/stages, Dockerfile, deployment scripts, and environment-specific configurations. Includes comments explaining each step.
Migrate between libraries/frameworks
intermediatePlan and execute migration from [old library] to [new library] in our codebase. Start by analyzing all usages of [old library], create a compatibility layer if needed, then provide step-by-step migration plan for each file. Handle breaking changes and update tests accordingly.Expected Output
Comprehensive migration analysis, compatibility layer implementation, file-by-file migration plan with code examples, and updated test files. Includes risk assessment.

Tips for Better Prompts
Always open the relevant file before prompting—Cursor reads your current context. I've found that asking 'refactor this function' with the file open yields 70% better results than describing it from memory.
Chain prompts for complex tasks: Start with 'analyze this problem', then 'suggest 3 solutions', then 'implement option 2'. This mimics how senior engineers think and gives Cursor better context at each step.
Common mistake: Being too vague. Instead of 'fix this bug', say 'the bug occurs when [condition] and shows [error]. The relevant code is in [files].' Specificity triggers Cursor's codebase analysis capabilities.
Use @ references to point Cursor to specific files or symbols in your codebase. For example, 'Refactor the UserService class (@app/services/UserService.ts) to use dependency injection' gives dramatically better results.
Customize prompts for your stack: Mention your specific libraries (React vs Vue, Express vs Fastify). Cursor knows thousands of libraries and will use appropriate patterns for each ecosystem.
