SwiftBot is a blazing-fast Telegram bot framework built for performance and simplicity. With 30× faster command routing, HTTP/2 connection pooling, and zero external dependencies for core functionality.

## 🚀 Key Features

### Performance
- **30× Faster Routing**: Trie-based O(m) command lookup vs O(n) linear search
- **HTTP/2 Multiplexing**: 100+ concurrent requests per connection
- **Connection Pooling**: 50-100 persistent keep-alive connections
- **Worker Pool**: 50+ concurrent update processing workers
- **Circuit Breaker**: Automatic failure recovery

### Developer Experience
- **Telethon-Style Decorators**: Clean, intuitive syntax
- **Regex Pattern Matching**: Powerful message filtering
- **Composable Filters**: `F.text & F.private & ~F.forwarded`
- **Type Hints**: Full IDE support
- **Rich Context Object**: Easy access to all update data

### Enterprise Features
- **Cache-Based Middleware**: No external dependencies
- **Centralized Exception Handling**: Comprehensive error recovery
- **Performance Monitoring**: Built-in metrics
- **Zero Dependencies**: Core functionality without external storage

## 📦 Installation

```bash
pip install swiftbot

# Or from GitHub
pip install git+https://github.com/Arjun-M/SwiftBot.git
```

## 🎯 Quick Start

```python
import asyncio
from swiftbot import SwiftBot
from swiftbot.types import Message
from swiftbot.middleware import Logger, RateLimiter

# Initialize bot
client = SwiftBot(
    token="YOUR_BOT_TOKEN",
    worker_pool_size=50,
    enable_http2=True
)

# Add cache-based middleware
client.use(Logger(level="INFO"))
client.use(RateLimiter(rate=10, per=60))

# Simple command handler
@client.on(Message(pattern=r"^/start"))
async def start(ctx):
    await ctx.reply("Hello! I'm SwiftBot 🚀")

# Run bot
asyncio.run(client.run())
```

## 📖 Documentation

### Client Initialization

```python
from swiftbot import SwiftBot

client = SwiftBot(
    token="YOUR_BOT_TOKEN",
    parse_mode="HTML",
    worker_pool_size=50,
    max_connections=100,
    timeout=30,
    enable_http2=True,
    enable_centralized_exceptions=True
)
```

### Event Handlers

```python
from swiftbot.types import Message, CallbackQuery

# Message handlers
@client.on(Message())  # All messages
@client.on(Message(text="hello"))  # Exact text match
@client.on(Message(pattern=r"^/start"))  # Regex pattern

# Callback query handlers
@client.on(CallbackQuery(data="button_1"))
@client.on(CallbackQuery(pattern=r"page_(\d+)"))
```

### Context Object

```python
@client.on(Message())
async def handler(ctx):
    # Message data
    ctx.text          # Message text
    ctx.user          # Sender user object
    ctx.chat          # Chat object
    ctx.args          # Command arguments
    ctx.match         # Regex match object

    # Reply methods
    await ctx.reply("Text")
    await ctx.edit("New text")
    await ctx.delete()
    await ctx.forward_to(chat_id)
```

### In-built Middleware

```python
from swiftbot.middleware import Logger, RateLimiter, Auth, AnalyticsCollector

# Logging (no external dependencies)
client.use(Logger(level="INFO", format="colored"))

# Rate limiting (in-memory cache)
client.use(RateLimiter(rate=10, per=60))

# Authentication (cache-based user management)
client.use(Auth(admin_list=[123, 456]))

# Analytics (cache-based metrics)
client.use(AnalyticsCollector(enable_real_time=True))
```

## 🏗️ Architecture

### Cache-Based Design
- **No External Dependencies** for core functionality
- **In-Memory Caching** for middleware data
- **Automatic Cleanup** of old cache entries
- **High Performance** without database overhead

### Connection Pool
- HTTP/2 multiplexing for 100+ concurrent streams
- Persistent keep-alive connections
- Automatic connection recycling
- Circuit breaker for fault tolerance

### Worker Pool
- Configurable worker count (10-100)
- Priority queue for updates
- Backpressure handling
- Load balancing
