# Cursor Reference Architecture

Reference architecture patterns for optimizing Cursor IDE project setup. Covers directory structure, rules organization, indexing strategy, and multi-project configuration for maximum AI effectiveness.

## Project Layout for Cursor

A well-structured project makes AI features significantly more effective:

```
my-project/
├── .cursor/
│   └── rules/
│       ├── project.mdc          # alwaysApply: true (stack, conventions)
│       ├── security.mdc         # alwaysApply: true (security constraints)
│       ├── typescript.mdc       # globs: "**/*.ts,**/*.tsx"
│       ├── api-routes.mdc       # globs: "src/api/**/*.ts"
│       ├── database.mdc         # globs: "src/db/**/*.ts,prisma/**"
│       └── testing.mdc          # globs: "**/*.test.ts,**/*.spec.ts"
├── .cursorignore                # Exclude from AI + indexing
├── .cursorindexingignore        # Exclude from indexing only
├── .gitignore
├── src/
│   ├── api/                     # API routes
│   ├── services/                # Business logic
│   ├── db/                      # Database layer
│   ├── types/                   # Shared TypeScript types
│   ├── utils/                   # Utility functions
│   └── components/              # UI components
├── tests/
├── prisma/
├── docs/                        # Architecture docs (good for @Docs)
└── package.json
```

### Why This Structure Helps Cursor

1. **Glob patterns work predictably**: `src/api/**/*.ts` cleanly scopes API rules
2. **@Files references are intuitive**: `@src/types/user.ts` is discoverable
3. **Indexing is focused**: clear separation of code vs build output vs data
4. **Rules inheritance**: project-level always-on + directory-scoped rules

## Rules Architecture

### Layer 1: Always-On Global Rules

```yaml
# .cursor/rules/project.mdc
---
description: "Core project context and conventions"
globs: ""
alwaysApply: true
---
# SaaS Dashboard Application

Stack: Next.js 15 (App Router), TypeScript 5.7, PostgreSQL 16, Prisma 6
Auth: NextAuth.js v5 with GitHub OAuth
Styling: Tailwind CSS 4
Testing: Vitest + Playwright
Package manager: pnpm

## Architecture Decisions
- Server Components by default, "use client" only when needed
- Repository pattern for database access
- Zod schemas for all external input validation
- Result types for error handling (never throw from services)
```

### Layer 2: Security (Always-On)

```yaml
# .cursor/rules/security.mdc
---
description: "Security constraints for all AI-generated code"
globs: ""
alwaysApply: true
---
# Security Requirements
- NEVER hardcode secrets, API keys, or passwords
- ALWAYS use parameterized queries (no string interpolation in SQL)
- ALWAYS validate and sanitize user input with Zod
- NEVER disable CORS, CSRF protection, or TLS verification
- Use httpOnly, secure, sameSite cookies for auth tokens
- Rate limit all public API endpoints
```

### Layer 3: Technology-Specific (Glob-Scoped)

```yaml
# .cursor/rules/react-components.mdc
---
description: "React component patterns"
globs: "src/components/**/*.tsx,app/**/*.tsx"
alwaysApply: false
---
# Component Standards
- Named exports only (no default exports)
- Props interface: {ComponentName}Props
- Use forwardRef for interactive components
- Colocate tests: Component.test.tsx next to Component.tsx
- Loading states: use Suspense boundaries, not conditional rendering
```

```yaml
# .cursor/rules/api-routes.mdc
