Cursor IDE .cursorrules Pack for Production‑Ready React + TypeScript Projects

Stop fighting Cursor’s inconsistent React outputs. Start generating production‑ready code on the first try.

You know the pain: Cursor gives you components with random structures, hooks that don’t follow React rules, TypeScript that compiles but isn’t safe, and test files that feel like afterthoughts. You waste time correcting the AI instead of building features. And every new file generation feels like starting from zero.

This .cursorrules pack fixes that. You get a set of 12 production‑ready rule files engineered to force Cursor into consistent React + TypeScript patterns. Every component, hook, util, and test file is generated with strict architecture, stable dependencies, safe TypeScript, and secure data handling—without you having to explain anything to the model.

What’s Included:
- 1 React Component Rule enforcing structure, props typing, safety checks, and file layout
- 1 Hooks Rule ensuring correct dependency patterns and no stale closures
- 2 TypeScript Strictness Rules covering generics, return types, narrowing, and common unsafe patterns
- 1 State Management Rule for predictable selectors, actions, and store shape
- 1 API Layer Rule enforcing typed fetchers, schema validation, and safe client-side data handling
- 1 Security Rule preventing unsafe HTML injection and unsanitized values
- 2 Vitest Rules for test file scaffolding, mocks, and coverage patterns
- 1 File Structure Rule guaranteeing consistent folder and naming conventions
- 2 Utility + Helper Rules for reusable patterns Cursor normally gets wrong

These rules come from real production audits of React teams where AI‑generated code caused regressions, performance bugs, and security issues. Every file is based on patterns used in apps serving millions of users under strict TypeScript and testing requirements.

Who This Is For:
- React devs using Cursor daily who want stable, predictable generations
- Teams enforcing consistent architecture across contributors
- Solo builders who want production‑quality output without memorizing every best practice

Who This Is NOT For:
- Developers building simple prototypes with no need for structure
- Anyone who wants Cursor to be “creative” instead of consistent

If this doesn’t save you at least 5 hours in your first week, reach out for a full refund.
