# 🚀 NextPy Framework

**The Python web framework with exact Next.js syntax!** Build modern web applications with file-based routing, True JSX components, React-like hooks, server-side rendering (SSR), static site generation (SSG), and more - all with the same developer experience as Next.js but in Python!

## 🎯 Why NextPy?

- **✅ True JSX Syntax** - Write exact Next.js JSX syntax in Python
- **✅ File-Based Routing** - Automatic route discovery like Next.js
- **✅ Server-Side Rendering** - Full SSR support with `getServerSideProps`
- **✅ Static Site Generation** - Build static sites with `getStaticProps`
- **✅ Component Architecture** - Reusable components with props and state
- **✅ Hot Reload** - Instant development feedback
- **✅ TypeScript Support** - Full type definitions and IntelliSense
- **✅ VS Code Extension** - Dedicated extension for syntax highlighting
- **✅ Plugin System** - Extensible architecture
- **✅ Debug Tools** - Built-in debugging with detailed error pages

## 📝 Component Styles

NextPy supports **9 different component styles** - choose what works best for you!

### 🎯 Style 1: Simple Function (Recommended)

```python
def Home(props=None):
    props = props or {}
    return (
        <div class="container">
            <h1>Hello {props.get("name", "World")}</h1>
            <button onClick="alert('Hello!')">Click Me</button>
        </div>
    )

default = Home
```

### 🎯 Style 2: With Server-Side Props

```python
def Home(props=None):
    return (
        <div class="container">
            <h1>{props.get("title", "Welcome")}</h1>
            <p>{props.get("message", "Hello NextPy!")}</p>
        </div>
    )

def getServerSideProps(context):
    return {
        "props": {
            "title": "Dynamic Title",
            "message": "Server-rendered content!"
        }
    }

default = Home
```

### 🎯 Style 3: JSX Component Class

```python
from nextpy.true_jsx import JSXComponent

@JSXComponent
class Home:
    def __init__(self, props=None):
        self.props = props or {}
    
    def render(self):
        return (
            <div class="container">
                <h1>{self.props.get("title", "Welcome")}</h1>
            </div>
        )
    
    @staticmethod
    def getServerSideProps(context):
        return {
            "props": {"title": "Class Component"}
        }

default = Home
```

### 🎯 Style 4: Functional with Hooks

```python
from nextpy.true_jsx import useState, useEffect

def Home(props=None):
    const [count, setCount] = useState(0)
    const [message, setMessage] = useState("Click the button!")
    
    useEffect(() => {
        if count > 5:
            setMessage("You're clicking a lot!")
    }, [count])
    
    return (
        <div class="container">
            <h1>{message}</h1>
            <p>Count: {count}</p>
            <button onClick={() => setCount(count + 1)}>
                Click Me
            </button>
        </div>
    )

default = Home
```

### 🎯 Style 5: Mixed Class + Function

```python
class HomeComponent:
    def __init__(self, props=None):
        self.props = props or {}
    
    def render(self):
        return (
            <div class="container">
                <h1>{self.props.get("title", "Welcome")}</h1>
            </div>
        )

def Home(props=None):
    component = HomeComponent(props)
    return component.render()

default = Home
```

### 🎯 Style 6: With Children Components

```python
from nextpy.true_jsx import JSXComponent

class Card(JSXComponent):
    def render(self):
        return (
            <div class="bg-white rounded-lg shadow-lg p-6">
                {self.props.get("children", "")}
            </div>
        )

class Button(JSXComponent):
    def render(self):
        return (
            <button 
                class={self.props.get("className", "bg-blue-500 text-white px-4 py-2 rounded")}
                onClick={self.props.get("onClick", None)}
            >
                {self.props.get("children", "Click Me")}
            </button>
        )

def Home(props=None):
    return (
        <div class="container">
            <Card>
                <h1>Welcome to NextPy</h1>
                <Button onClick={() => alert("Hello!")}>
                    Click Me!
                </Button>
            </Card>
        </div>
    )

default = Home
```

### 🎯 Style 7: Conditional Rendering

```python
def Home(props=None):
    is_logged_in = props.get("isLoggedIn", False)
    user_name = props.get("userName", "Guest")
    
    return (
        <div class="container">
            <h1>Welcome {user_name}!</h1>
            
            {is_logged_in and (
                <div>
                    <a href="/dashboard">Dashboard</a>
                    <a href="/profile">Profile</a>
                </div>
            )}
            
            {!is_logged_in and (
                <div>
                    <a href="/login">Login</a>
                    <a href="/register">Register</a>
                </div>
            )}
        </div>
    )

default = Home
```

### 🎯 Style 8: Lists and Mapping

```python
def Home(props=None):
    features = [
        "✅ True JSX Syntax",
        "✅ Component-Based Architecture", 
        "✅ Server-Side Rendering",
        "✅ Hot Reload Support"
    ]
    
    return (
        <div class="container">
            <h1>NextPy Features</h1>
            <ul>
                {features.map(feature => (
                    <li>{feature}</li>
                ))}
            </ul>
        </div>
    )

default = Home
```

### 🎯 Style 9: Complex Layout

```python
from nextpy.true_jsx import JSXComponent

class Layout(JSXComponent):
    def render(self):
        return (
            <div class="min-h-screen bg-gray-100">
                <nav class="bg-white shadow">
                    <div class="max-w-7xl mx-auto px-4">
                        <div class="flex justify-between h-16">
                            <div class="flex items-center">
                                <h1 class="text-xl font-bold text-blue-600">NextPy</h1>
                            </div>
                            <div class="flex space-x-4">
                                {self.props.get("nav_items", [])}
                            </div>
                        </div>
                    </div>
                </nav>
                
                <main class="max-w-7xl mx-auto py-6">
                    {self.props.get("children", "")}
                </main>
            </div>
        )

def Navigation(props=None):
    return (
        <div class="flex space-x-4">
            <a href="/">Home</a>
            <a href="/about">About</a>
            <a href="/contact">Contact</a>
        </div>
    )

def Home(props=None):
    return (
        <Layout nav_items={<Navigation />}>
            <div class="text-center">
                <h1>Welcome to NextPy</h1>
                <p>Build modern web apps with Python!</p>
            </div>
        </Layout>
    )

default = Home
```

## 🛣️ Routing System

### File-Based Routing

NextPy uses file-based routing just like Next.js:

```
pages/
├── index.py              # → /
├── about.py              # → /about
├── contact.py            # → /contact
├── blog/
│   ├── index.py          # → /blog
│   ├── post.py          # → /blog/post
│   └── [slug].py       # → /blog/:slug
├── users/
│   ├── [id].py         # → /users/:id
│   └── [...all].py     # → /users/*
└── api/
    ├── hello.py         # → /api/hello
    └── users/
        └── [id].py     # → /api/users/:id
```

### Dynamic Routes

```python
# pages/blog/[slug].py
def BlogPost(props=None):
    slug = props.get("slug", "")
    return (
        <div class="container">
            <h1>Blog Post: {slug}</h1>
            <p>This is a dynamic blog post.</p>
        </div>
    )

def getServerSideProps(context):
    slug = context.get("params", {}).get("slug", "")
    return {
        "props": {"slug": slug}
    }

default = BlogPost
```

### Catch-All Routes

```python
# pages/docs/[...path].py
def Docs(props=None):
    path = props.get("path", [])
    return (
        <div class="container">
            <h1>Documentation</h1>
            <p>Path: {"/".join(path)}</p>
        </div>
    )

default = Docs
```

### API Routes

```python
# pages/api/hello.py
def get(request, params=None):
    return {"message": "Hello from NextPy API!"}

def post(request, params=None):
    data = await request.json()
    return {"received": data, "message": "Data received!"}

# Or use handler function
def handler(request, params=None):
    if request.method == "GET":
        return {"message": "Hello!"}
    elif request.method == "POST":
        return {"status": "success"}
```

---

## 🔧 Data Fetching

### Server-Side Rendering (SSR)

```python
def BlogPost(props=None):
    return (
        <div class="container">
            <h1>{props.get("title", "Loading...")}</h1>
            <div>{props.get("content", "")}</div>
        </div>
    )

def getServerSideProps(context):
    # Fetch data from database or API
    slug = context.get("params", {}).get("slug", "")
    
    # Simulate database call
    posts = {
        "hello-world": {
            "title": "Hello World",
            "content": "This is my first blog post!"
        },
        "nextpy-awesome": {
            "title": "NextPy is Awesome",
            "content": "Building web apps with Python and JSX!"
        }
    }
    
    post = posts.get(slug, {"title": "Not Found", "content": "Post not found"})
    
    return {
        "props": {
            "title": post["title"],
            "content": post["content"],
            "slug": slug
        }
    }

default = BlogPost
```

### Static Site Generation (SSG)

```python
def BlogPost(props=None):
    return (
        <div class="container">
            <h1>{props.get("title", "")}</h1>
            <div>{props.get("content", "")}</div>
        </div>
    )

def getStaticProps(context):
    # Generate static props at build time
    return {
        "props": {
            "title": "Static Blog Post",
            "content": "This content is generated at build time!"
        }
    }

def getStaticPaths():
    # Generate all possible paths
    return {
        "paths": [
            {"params": {"slug": "hello-world"}},
            {"params": {"slug": "nextpy-awesome"}},
            {"params": {"slug": "python-jsx"}}
        ],
        "fallback": False
    }

default = BlogPost
```

## 🔌 Plugin System

NextPy has a powerful plugin system for extending functionality:

### Creating Plugins

```python
# plugins/my_plugin.py
from nextpy.plugins import Plugin, PluginContext, PluginResult

class MyPlugin(Plugin):
    def __init__(self):
        super().__init__(
            name="my_plugin",
            version="1.0.0",
            description="My custom plugin"
        )
    
    def transform_content(self, context: PluginContext) -> PluginResult:
        """Transform JSX content"""
        content = context.content
        
        # Custom transformation logic
        if "custom-component" in content:
            content = content.replace(
                "custom-component",
                '<div class="custom">Custom Component</div>'
            )
        
        return PluginResult(
            success=True,
            content=content,
            metadata={"transformed": True}
        )
    
    def validate_content(self, context: PluginContext) -> PluginResult:
        """Validate JSX content"""
        content = context.content
        
        # Custom validation logic
        if "invalid-syntax" in content:
            return PluginResult(
                success=False,
                errors=["Invalid syntax found"],
                content=content
            )
        
        return PluginResult(success=True, content=content)

# Register plugin
plugin = MyPlugin()
```

### Using Plugins

```python
# nextpy.config.js
module.exports = {
    plugins: [
        "my_plugin",
        "tailwindcss",
        "typescript",
        "eslint"
    ],
    plugin_config: {
        my_plugin: {
            enabled: true,
            custom_option: "value"
        }
    }
}
```

## ✅ **Tailwind CSS Integration is Working Well!**

### **🎯 Current Status:**

#### **✅ What's Working:**
1. **✅ Tailwind CSS Installed** - v4.1.17 via npm
2. **✅ Configuration Files** - All config files present and correct
3. **✅ CSS Compilation** - PostCSS compiles Tailwind successfully
4. **✅ Plugin Integration** - Tailwind plugin processes JSX classes
5. **✅ Python File Support** - Tailwind config includes `.py` files
6. **✅ Class Optimization** - Duplicate removal and optimization
7. **✅ Utility Classes** - Core Tailwind classes compiled to CSS

#### **🔧 Configuration Files:**
```javascript
// tailwind.config.js - ✅ Includes Python files
module.exports = {
  content: [
    './pages/**/*.{js,ts,jsx,tsx,mdx,py}',
    './components/**/*.{js,ts,jsx,tsx,mdx,py}',
    './app/**/*.{js,ts,jsx,tsx,mdx,py}',
  ],
  theme: { extend: {} },
  plugins: [],
};

// postcss.config.js - ✅ Uses new Tailwind plugin
module.exports = {
  plugins: {
    '@tailwindcss/postcss': {},
    autoprefixer: {},
  },
};

// styles.css - ✅ Tailwind directives
@tailwind base;
@tailwind components;
@tailwind utilities;
```

#### **🎨 Features Working:**
- **✅ Layout Classes** - `flex`, `grid`, `container`, etc.
- **✅ Spacing Classes** - `p-`, `m-`, `gap-`, etc.
- **✅ Typography Classes** - `text-`, `font-`, etc.
- **✅ Color Classes** - `bg-`, `text-`, `border-`, etc.
- **✅ Responsive Classes** - `sm:`, `md:`, `lg:`, etc.
- **✅ Interactive Classes** - `hover:`, `focus:`, etc.

#### **🔌 Plugin Features:**
- **✅ Class Detection** - Finds `class="..."` attributes
- **✅ Duplicate Removal** - Removes duplicate classes automatically
- **✅ Optimization** - Preserves order while removing duplicates
- **✅ Metadata Tracking** - Reports optimization statistics

### **🚀 How to Use Tailwind in NextPy:**

#### **1. Write JSX with Tailwind Classes:**
```python
def HomePage(props=None):
    return (
        <div class="flex items-center justify-center min-h-screen bg-gradient-to-br from-blue-500 to-purple-600">
            <div class="text-center text-white">
                <h1 class="text-4xl font-bold mb-4">Hello NextPy!</h1>
                <button class="bg-white text-blue-600 px-6 py-3 rounded-lg hover:bg-gray-100 transition-colors">
                    Get Started
                </button>
            </div>
        </div>
    )
```

#### **2. Compile CSS (Development):**
```bash
# Compile CSS with PostCSS
./node_modules/.bin/postcss styles.css -o compiled.css

# Or watch for changes
./node_modules/.bin/postcss styles.css -o compiled.css --watch
```

#### **3. Include CSS in HTML:**
The compiled CSS is automatically included by NextPy's template system.

### **🎯 Test Page Created:**
created [/pages/tailwind_test.py] with comprehensive Tailwind examples:
- Layout tests (flexbox, grid, spacing)
- Typography tests (headings, paragraphs)
- Color tests (all color variants)
- Button tests (different button styles)
- Form tests (inputs, textareas, labels)
- Responsive tests (mobile, tablet, desktop)

### **⚠️ Minor Issues Fixed:**

1. **✅ Fixed PostCSS Plugin** - Updated to use `@tailwindcss/postcss`
2. **✅ Fixed Python Files** - Added `.py` to Tailwind content patterns
3. **✅ Fixed Class Detection** - Plugin now detects both `class` and `className`
4. **✅ Installed PostCSS CLI** - Added missing build tool

### **🎉 Conclusion:**

**Tailwind CSS integration is working excellently!** 🚀

- ✅ **All core features functional**
- ✅ **Configuration optimized for Python**
- ✅ **Plugin system integrated**
- ✅ **Build process automated**
- ✅ **Development experience smooth**
