SwiftBot - Ultra-Fast Telegram Bot Client

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

pip install swiftbot

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

🎯 Quick Start

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

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

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

@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

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
