📦 Installation

Quick Install

pip install ultrafast-client

Development Install

# Clone the repository
git clone https://github.com/techgopal/ultrafast-client.git
cd ultrafast-client

# Install with development dependencies
pip install -e ".[dev]"

🚀 Quick Start

Synchronous Usage

import ultrafast_client as uc

# Simple GET request
client = uc.HttpClient()
response = client.get("https://api.github.com/users/octocat")
print(response.json())

# POST with JSON
data = {"name": "UltraFast", "description": "Blazing fast HTTP client"}
response = client.post("https://httpbin.org/post", json=data)
print(f"Status: {response.status_code}")

Asynchronous Usage

import asyncio
import ultrafast_client as uc

async def main():
    client = uc.AsyncHttpClient()
    
    # Concurrent requests
    tasks = [
        client.get("https://httpbin.org/delay/1"),
        client.get("https://httpbin.org/delay/2"),
        client.get("https://httpbin.org/json")
    ]
    
    responses = await asyncio.gather(*tasks)
    for response in responses:
        print(f"Status: {response.status_code}")

asyncio.run(main())

Session Management

import ultrafast_client as uc

# Persistent sessions with automatic cookie handling
with uc.Session() as session:
    session.headers.update({"User-Agent": "UltraFast/1.0"})
    
    # Login
    login_data = {"username": "user", "password": "pass"}
    session.post("https://httpbin.org/post", data=login_data)
    
    # Authenticated request (cookies preserved)
    profile = session.get("https://httpbin.org/cookies")
    print(profile.json())

Advanced Protocol Configuration

import ultrafast_client as uc

# Configure HTTP/2 with fallback to HTTP/1.1
protocol_config = uc.ProtocolConfig(
    preferred_version=uc.HttpVersion.Http2,
    enable_http2=True,
    fallback_strategy=uc.ProtocolFallback.Http2ToHttp1,
    protocol_negotiation_timeout=10.0
)

client = uc.HttpClient(protocol_config=protocol_config)
response = client.get("https://www.cloudflare.com")  # Will use HTTP/2 if available
print(f"Protocol used: {response.headers().get('server', 'Unknown')}")

retry_config = uc.RetryConfig(max_retries=3, initial_delay=0.1)
timeout_config = uc.TimeoutConfig(connect_timeout=5.0, read_timeout=10.0)

client = uc.HttpClient(
    retry_config=retry_config,
    timeout_config=timeout_config
)

# Call another service
try:
    response = client.post(
        "https://user-service/api/users",
        json={"name": "John Doe", "email": "[e-mail]"}
    )
    if response.ok():

        print(f"✅ User created with ID: {user_id}")
    else:
        print(f"❌ Failed to create user: {response.status_code}")
