A modern, production-ready Python web framework that combines the best of Flask and FastAPI with zero-configuration auto-discovery, built-in security, and enterprise-grade features.

## ✨ Why Choose ZestAPI?

ZestAPI goes beyond what Flask and FastAPI offer by providing a **zero-boilerplate** experience with **enterprise-grade** features out of the box:

- **⚡ Ultra Performance**: ASGI 3.0 + orjson delivering 2x faster JSON responses
- **🎯 Zero-Config Auto-Discovery**: Routes, middleware, and plugins auto-detected from file structure
- **🔐 Enterprise Security**: JWT authentication, rate limiting, CORS, input validation built-in
- **🛠 Developer Excellence**: Powerful CLI, hot reload, comprehensive error handling, auto-logging
- **📦 Production-First**: Health checks, metrics, graceful shutdown, Docker-ready
- **🤖 AI-Optimized**: LLM-friendly structure for AI-assisted development
- **🔌 Plugin Ecosystem**: Extensible architecture with auto-loading plugins
- **📡 WebSocket Support**: Real-time features with WebSocket routing

## ⚡ Quick Start

### Installation

```bash
pip install zestapi
```

### Create Your First API (3 ways)

#### 1. **Zero-Config Method** (Recommended)
```bash
zest init my-api
cd my-api
python main.py
```
Your API with auto-discovery is running at `http://localhost:8000` 🎉

#### 2. **Single File Method**
```python
from zestapi import ZestAPI, ORJSONResponse

app_instance = ZestAPI()

@app_instance.route("/")
async def homepage(request):
    return ORJSONResponse({"message": "Hello, ZestAPI!"})

@app_instance.route("/users/{user_id}")
async def get_user(request):
    user_id = request.path_params["user_id"]
    return ORJSONResponse({"user_id": user_id, "name": f"User {user_id}"})

# WebSocket support
@app_instance.websocket_route("/ws")
async def websocket_endpoint(websocket):
    await websocket.accept()
    await websocket.send_json({"message": "Connected to ZestAPI WebSocket!"})
    await websocket.close()

app = app_instance.app  # ASGI app for deployment

if __name__ == "__main__":
    app_instance.run()
```

#### 3. **Enterprise Structure** (Auto-Discovery)
```
my-api/
├── main.py              # Entry point
├── .env                 # Configuration
├── app/
│   ├── routes/          # Auto-discovered routes
│   │   ├── users.py     # → /users endpoints
│   │   ├── products.py  # → /products endpoints
│   │   └── api/
│   │       └── v1.py    # → /api/v1 endpoints
│   └── plugins/         # Auto-loaded plugins

## 🛠 Powerful CLI Tools

ZestAPI includes a comprehensive CLI for rapid development:

```bash
# Initialize new project with full structure
zest init my-api              

# Generate route files with CRUD operations
zest generate route users     # Creates app/routes/users.py with GET/POST/PUT/DELETE
zest generate route products  # Creates app/routes/products.py

# Generate plugin files with boilerplate
zest generate plugin auth     # Creates app/plugins/auth.py
zest generate plugin logger   # Creates app/plugins/logger.py

# View all discovered routes and endpoints
zest route-map               # Shows complete route tree

# Check framework version
zest version                 # Show ZestAPI version info
```

### Auto-Generated Route Example
When you run `zest generate route users`, it creates:

```python
# app/routes/users.py (auto-generated)
from zestapi import route, ORJSONResponse

@route("/users", methods=["GET"])
async def users_index(request):
    return ORJSONResponse({"users": "List all users"})

@route("/users/{user_id}", methods=["GET"])
async def users_get_item(request):
    user_id = request.path_params["user_id"]
    return ORJSONResponse({
        "id": user_id,
        "type": "user",
        "message": f"Getting user {user_id}"
    })

@route("/users", methods=["POST"])
async def users_create(request):
    data = await request.json()
    return ORJSONResponse({
        "message": "Created new user",
        "data": data
    }, status_code=201)
```

## 🔥 Advanced Features

### 1. **Smart Auto-Discovery**
ZestAPI automatically discovers and registers routes from your file structure:

```python
# app/routes/users.py → Automatically creates /users/* endpoints
# app/routes/products.py → Automatically creates /products/* endpoints
# app/routes/api/v1.py → Automatically creates /api/v1/* endpoints
# app/plugins/analytics.py → Automatically loaded and registered
```

### 2. **Enterprise-Grade Security**
```python
# JWT Authentication (built-in)
from zestapi import create_access_token, JWTAuthBackend

# Create token
token = create_access_token({"sub": "user123", "role": "admin"})

# Rate limiting (automatic per-route)
# Configured via environment: RATE_LIMIT=1000/minute

# CORS (configurable)
# Input validation with Pydantic models
from pydantic import BaseModel

class UserModel(BaseModel):
    name: str
    email: str
    age: int

@route("/users", methods=["POST"])
async def create_user(request):
    data = await request.json()
    user = UserModel(**data)  # Automatic validation
    return ORJSONResponse({"user": user.dict()})
```

### 3. **WebSocket Support**
```python
from zestapi import ZestAPI

app_instance = ZestAPI()

@app_instance.websocket_route("/ws/chat")
async def websocket_chat(websocket):
    await websocket.accept()
    while True:
        data = await websocket.receive_json()
        await websocket.send_json({"echo": data})
```

### 4. **Plugin System**
```python
# app/plugins/analytics.py
class AnalyticsPlugin:
    def __init__(self, app):
        self.app = app

    def register(self):
        @self.app.route("/analytics/stats")
        async def get_stats(request):
            return ORJSONResponse({"requests": 1000, "users": 50})
```

### 5. **Production Configuration**
```bash
# .env file
JWT_SECRET=your-super-secret-production-key
DEBUG=false
LOG_LEVEL=WARNING
RATE_LIMIT=1000/minute
CORS_ORIGINS=["https://yourdomain.com"]
HOST=0.0.0.0
PORT=8000
```
