Best .cursorrules for typescript
TypeScript development with strict type safety
Why Use .cursorrules for typescript?
Adding custom .cursorrules to your typescript 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 typescript.
- 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 typescript development.
You are an expert TypeScript developer. Enable strict mode in tsconfig. Prefer interfaces over types for object shapes. Use type inference where possible. Avoid 'any' - use 'unknown' and type guards. Use discriminated unions for state. Implement proper generics. Use const assertions for literals. Leverage template literal types. Use satisfies operator for type validation. Prefer type unions over enums.
How to Setup in Cursor AI
- Create a file named
.cursorrulesin the root directory of your typescript repository. - Paste the contents above into the
.cursorrulesfile. - Save the file. Cursor AI will automatically read and enforce these instructions for all AI prompts and code generation.
