# React/Next.js Development Workflow

## Overview

Specialized workflow for building React and Next.js 14+ applications with modern patterns including App Router, Server Components, TypeScript, and Tailwind CSS.

## When to Use This Workflow

Use this workflow when:
- Building new React applications
- Creating Next.js 14+ projects with App Router
- Implementing Server Components
- Setting up TypeScript with React
- Styling with Tailwind CSS
- Building full-stack Next.js applications

## Workflow Phases

- `app-builder` - Application scaffolding
- `senior-fullstack` - Full-stack guidance
- `nextjs-app-router-patterns` - Next.js 14+ patterns
- `typescript-pro` - TypeScript setup

#### Actions
1. Choose project type (React SPA, Next.js app)
2. Select build tool (Vite, Next.js, Create React App)
3. Scaffold project structure
4. Configure TypeScript
5. Set up ESLint and Prettier

#### Copy-Paste Prompts
```
