NetworkPype

A Python library for building efficient network communication pipelines, supporting both REST and WebSocket protocols with built-in rate limiting and time synchronization.

Features

• 🔄 Dual Protocol Support: Unified factory for REST and WebSocket connections
• 🚦 Async Rate Limiting: Built-in throttler with multiple concurrent limits and weighted consumption
• ⏰ Time Synchronization: Rolling-window server time alignment for timestamp-sensitive APIs
• 🏭 Factory Pattern: ConnectionsFactory and ConnectionManagersFactory for clean lifecycle management
• 🔌 Processor Pipeline: Composable pre/post processors for request transformation and response handling
• 🛡️ Authentication: Abstract Auth base class supporting any scheme (API key, OAuth, HMAC, JWT)
• 🔒 Type Safe: Fully typed with MyPy strict mode
• 🧪 Well Tested: Comprehensive test suite with high coverage

Installation

# Using pip
pip install networkpype

# Using uv
uv add networkpype

Quick Start

import asyncio
from decimal import Decimal

from networkpype.factory import ConnectionManagersFactory
from networkpype.rest.method import RESTMethod
from networkpype.throttler.rate_limit import RateLimit
from networkpype.throttler.throttler import AsyncThrottler


async def main():
    throttler = AsyncThrottler(
        rate_limits=[RateLimit(limit_id="default", limit=10, time_interval=1.0)]
    )
    factory = ConnectionManagersFactory(throttler=throttler)

    manager = await factory.get_rest_manager()
    data = await manager.execute_request(
        url="https://api.example.com/v1/data",
        throttler_limit_id="default",
        method=RESTMethod.GET,
    )
    print(data)

    await factory.close()


asyncio.run(main())

Core Components

• Factory: Entry point for creating connections

  • ConnectionsFactory: Low-level aiohttp session management
  • ConnectionManagersFactory: High-level managers with auth, throttling, and processors

• REST: Full HTTP pipeline

  • RESTConnection: Raw aiohttp wrapper
  • RESTManager: Orchestrates throttling, auth, and pre/post processors
  • RESTRequest / RESTResponse: Type-safe request and response containers

• WebSocket: Persistent connection management

  • WebSocketConnection: Low-level connection with ping/pong handling
  • WebSocketManager: Message pipeline with auth and processors
  • WebSocketJSONRequest / WebSocketPlainTextRequest: Typed message types

• Throttler: Async rate limiting

  • AsyncThrottler: Multi-limit, weighted rate limiter
  • RateLimit: Declarative limit configuration with linked limits
  • AsyncRequestContext: Context manager for acquiring capacity

• Auth: Authentication framework

  • Auth: Abstract base — subclass to implement any authentication scheme

• TimeSynchronizer: Server time alignment

  • Rolling-window offset with median + weighted-average calculation
