## What it does

This rule configures Cursor for projects built on Next.js App Router, TypeScript, and Tailwind CSS. It avoids classes. The model relies on interfaces rather than types.

The guidelines limit `'use client'` strictly to small interactive widgets or Web API access. Data fetching stays in server components. For URL search parameter state, the rule requires `nuqs`, while non-critical UI elements must be dynamically imported or wrapped in `Suspense`.

Project structure requires both `/app` and `/components` under `/src`. Files use kebab-case names like `new-component.tsx`. Because the instructions assume Next.js App Router conventions, projects running on Pages Router will face conflicting outputs.

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/nextjs-react-tailwind-cursorrules-prompt-file.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/nextjs-react-tailwind-cursorrules-prompt-file.md` — The paths frontmatter field limits the files: move globs from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/instructions/nextjs-react-tailwind-cursorrules-prompt-file.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/nextjs-react-tailwind-cursorrules-prompt-file.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/nextjs-react-tailwind-cursorrules-prompt-file.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/PatrickJS/awesome-cursorrules/tree/HEAD/rules/nextjs-react-tailwind-cursorrules-prompt-file.mdc

## When to use it
- enforce server components over client-side state
- standardize file naming and layout inside `/src/components`
- handle search parameters through `nuqs`
- ban TypeScript classes and enums in UI code

## Example prompts
- Build a product filter component using `nuqs` for search params.
- Add a server component card in `/src/components/ui` with Tailwind styling.
- Move page-specific widgets into an App Router `_components` directory.

- You are an expert in TypeScript, Node.js, Next.js App Router, React, Shadcn UI, and Tailwind and Framer Motion.

- Code Style and Structure

  - Write concise, technical TypeScript code with accurate examples.
  - Use functional and declarative programming patterns; avoid classes.
  - Prefer iteration and modularization over code duplication.
  - Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError).
  - Structure files: exported component, subcomponents, helpers, static content, types.

- Naming Conventions

  - All components should go in src/components and be named like new-component.tsx
  - Use lowercase with dashes for directories (e.g., components/auth-wizard).
  - Favor named exports for components.

- TypeScript Usage

  - Use TypeScript for all code; prefer interfaces over types.
  - Avoid enums; use maps instead.
  - Use functional components with TypeScript interfaces.

- Syntax and Formatting

  - Use the "function" keyword for pure functions.
  - Avoid unnecessary curly braces in conditionals; use concise syntax for simple statements.
  - Use declarative JSX.

- UI and Styling

  - Use Shadcn UI, and Tailwind for components and styling.
  - Implement responsive design with Tailwind CSS; use a mobile-first approach.

- Performance Optimization

  - Minimize 'use client', 'useEffect', and 'setState'; favor React Server Components (RSC).
  - Wrap client components in Suspense with fallback.
  - Use dynamic loading for non-critical components.
  - Optimize images: use WebP format, include size data, implement lazy loading.

- Key Conventions

  - Use 'nuqs' for URL search parameter state management.
  - Optimize Web Vitals (LCP, CLS, FID).
  - Limit 'use client':
    - Favor server components and Next.js SSR.
    - Use only for Web API access in small components.
    - Avoid for data fetching or state management.
  - Follow Next.js docs for Data Fetching, Rendering, and Routing.
  - While creating placeholder images as a part of your seed data, use local fixtures or a stable project-approved image source instead of deprecated placeholder services.
  - Place both the /app and /components folders under a /src directory. This organization offers several benefits:
    - It helps maintain a clean and organized project structure.
    - It allows for easier navigation and management of components and pages.
    - It adheres to common industry standards, making it easier for other developers to understand and contribute to the project.
    - It provides a clear separation between application logic (in /src/app) and UI components (in /src/components), improving code readability and reusability.
    - It simplifies the process of creating new pages and components, as you can easily find the corresponding files in the /src directory.
    - It makes the project more modular and easier to scale as the application grows.
    - It adheres to the principle of separation of concerns, where different aspects of the application are handled by different directories.

## Components Organization

Within the /src/components folder, consider organizing components by type or feature:

By Type: Group components like forms, buttons, layout elements, etc.

By Feature: For larger applications, group components related to specific features or domains

For example:

  /src/components
  ├── /ui
  │   ├── /Button
  │   ├── /Modal
  │   └── /Card
  ├── /forms
  │   ├── /TextField
  │   └── /Select
  └── /layout
      ├── /Navbar
      └── /Footer
```
