httpplus 1.0.0

HTTPPlus - Professional HTTP Toolkit for Python. Advanced HTTP client with async support, circuit breakers, caching, and schema validation.

HTTPPlus

Professional HTTP Toolkit for Python - Production-ready utilities for modern HTTP operations with advanced features for building reliable APIs and microservices.

📦 Overview

HTTPPlus is a battle-tested, production-ready HTTP client library designed to handle complex real-world scenarios. Beyond basic HTTP requests, it provides enterprise-grade features like circuit breakers, intelligent retry logic, caching, and validation out-of-the-box.

Why HTTPPlus?

✅ Production-Ready - Battle-tested with comprehensive error handling
✅ Async/Await Support - High-performance concurrent requests with async-await
✅ Smart Retry Logic - Exponential backoff with jitter to prevent thundering herd
✅ Circuit Breaker - Automatic fault tolerance and graceful degradation
✅ Intelligent Caching - TTL-based response caching with thread safety
✅ Schema Validation - JSON Schema support for response validation
✅ Rate Limiting - Token bucket algorithm for controlling request rate
✅ Session Management - Persistent cookies, token refresh, and auth handling
✅ Minimal Dependencies - Only requires requests (with optional extras)
✅ Thread-Safe - Safe for multi-threaded and async applications

🎯 Quick Start

Simple Request

from httpplus import quick_get

# One-liner
response = quick_get("https://api.github.com/users/github")
print(response['name'])  # Output: GitHub

HTTP Client with Advanced Features

from httpplus import HTTPClient

# Create client with features enabled
client = HTTPClient(
    base_url="https://api.example.com",
    enable_caching=True,
    max_retries=3,
)

# Automatic caching, retries, and error handling
user = client.get("/users/123")
print(user)

Async Operations

from httpplus import AsyncHTTPClient
import asyncio

async def fetch_multiple():
    client = AsyncHTTPClient(base_url="https://api.example.com")
    
    # Concurrent requests
    user = await client.get("/users/123")
    posts = await client.get("/posts/456")
    
    return user, posts

# Run async code
data = asyncio.run(fetch_multiple())

Circuit Breaker for Resilience

from httpplus import HTTPClient, CircuitBreaker

client = HTTPClient(base_url="https://api.example.com")
breaker = CircuitBreaker(failure_threshold=5, reset_timeout=60)

# Add event handlers
breaker.add_on_open(lambda: print("⚠️  Circuit opened - too many failures"))
breaker.add_on_close(lambda: print("✅ Circuit closed - service recovered"))

try:
    if not breaker.is_open():
        response = client.get("/health")
except Exception as e:
    breaker.record_failure()

Response Validation

from httpplus import HTTPClient, SchemaValidator

# Define schema
user_schema = {
    "type": "object",
    "properties": {
        "id": {"type": "integer"},
        "name": {"type": "string"},
        "email": {"type": "string", "format": "email"}
    },
    "required": ["id", "name"]
}

validator = SchemaValidator(user_schema)
client = HTTPClient(base_url="https://api.example.com")

response = client.get("/users/123")
if validator.validate(response):
    print("✅ Response is valid")
else:
    print("❌ Validation errors:", validator.get_errors())

Rate Limiting

from httpplus import RateLimiter

# Limit to 100 requests per minute
limiter = RateLimiter(rate=100, window=60)

for i in range(150):
    limiter.acquire()  # Waits if necessary
    # Make request

Session with Authentication

from httpplus import HTTPClient

client = HTTPClient(base_url="https://api.example.com")
session = client.create_session("my_app")

# Set auth token (auto-refreshes on expiry)
session.set_auth_token("your_token_here", expires_in=3600)

# Use session for authenticated requests
response = client.get("/protected", session=session)

All requests use this token

protected_data = client.get("/protected/endpoint")

### Download with Progress
```python
from my_common_package import HTTPClient

client = HTTPClient()

def show_progress(current, total):
    percent = (current / total) * 100
    print(f"Downloaded {percent:.1f}%")

client.download_file(
