🚀 Quick Start

Basic HTTP Requests

import ultrafast_client as uc

# Create HTTP client
client = uc.HttpClient()

# GET request
response = client.get("https://api.github.com/users/octocat")
print(f"Status: {response.status_code} - {response.status_text()}")
print(f"User: {response.json()['name']}")

# POST with JSON
data = {"title": "Hello World", "body": "This is a test"}
response = client.post("https://httpbin.org/post", json=data)
print(f"Success: {response.ok()}")

# All HTTP methods supported
response = client.put("https://httpbin.org/put", json={"updated": True})
response = client.patch("https://httpbin.org/patch", json={"field": "value"})
response = client.delete("https://httpbin.org/delete")
response = client.head("https://httpbin.org/get")
response = client.options("https://httpbin.org/get")

Async Client

import asyncio
import ultrafast_client as uc

async def main():
    # Create async client
    client = uc.AsyncHttpClient()
    
    # Concurrent requests
    tasks = [
        client.get("https://httpbin.org/get"),
        client.get("https://api.github.com/users/octocat"),
        client.post("https://httpbin.org/post", json={"async": True})
    ]
    
    responses = await asyncio.gather(*tasks)
    for i, response in enumerate(responses):
        print(f"Request {i+1}: {response.status_code}")

# Run async code
asyncio.run(main())

Authentication

# Bearer Token
auth_config = uc.AuthConfig.bearer("your-api-token")
client = uc.HttpClient(auth_config=auth_config)
response = client.get("https://api.github.com/user")

# Basic Authentication
auth_config = uc.AuthConfig.basic("username", "password")
client = uc.HttpClient(auth_config=auth_config)
response = client.get("https://httpbin.org/basic-auth/username/password")

# API Key in Headers
headers = {"X-API-Key": "your-api-key"}
client = uc.HttpClient(headers=headers)
response = client.get("https://api.example.com/data")

HTTP/3 and Advanced Features

# HTTP/3 with automatic fallback
protocol_config = uc.ProtocolConfig.default()
protocol_config.fallback_strategy = uc.ProtocolFallback.Http3ToHttp2ToHttp1

client = uc.HttpClient(protocol_config=protocol_config)
response = client.get("https://cloudflare.com")  # Will use HTTP/3 if available

# Rate Limiting
rate_config = uc.RateLimitConfig(
    algorithm=uc.RateLimitAlgorithm.TokenBucket,
    requests_per_minute=60,
    burst_size=10
)
client = uc.HttpClient(rate_limit_config=rate_config)

# Retry Logic
retry_config = uc.RetryConfig(
    max_retries=3,
    initial_delay=1.0,
    max_delay=10.0,
    exponential_base=2.0
)
client = uc.HttpClient(retry_config=retry_config)

WebSocket Communication

# Sync WebSocket
ws_client = uc.WebSocketClient()
connection = ws_client.connect("wss://echo.websocket.org/")
connection.send_text("Hello WebSocket!")
message = connection.receive_text()
print(f"Received: {message}")
connection.close()

# Async WebSocket
async def websocket_example():
    ws_client = uc.AsyncWebSocketClient()
    connection = await ws_client.connect("wss://echo.websocket.org/")
    await connection.send_text("Hello Async WebSocket!")
    message = await connection.receive_text()
    print(f"Received: {message}")
    await connection.close()

asyncio.run(websocket_example())

Server-Sent Events

# Sync SSE
sse_client = uc.SSEClient()
stream = sse_client.connect("https://httpbin.org/stream/10")
for event in stream:
    print(f"Event: {event.data}")
stream.close()

# Async SSE
async def sse_example():
    sse_client = uc.AsyncSSEClient()
    stream = await sse_client.connect("https://httpbin.org/stream/10")
    async for event in stream:
        print(f"Event: {event.data}")
        if event.event_type == "close":
            break
    await stream.close()

🎯 Use Cases

API Integration

# GitHub API with authentication and rate limiting
auth = uc.AuthConfig.bearer("ghp_your_token")
rate_limit = uc.RateLimitConfig(requests_per_minute=60)  # GitHub's limit

client = uc.HttpClient(auth_config=auth, rate_limit_config=rate_limit)

# Get user information
user = client.get("https://api.github.com/user").json()
print(f"Hello, {user['name']}!")

# List repositories with pagination
repos = client.get("https://api.github.com/user/repos?per_page=100").json()
for repo in repos:
    print(f"⭐ {repo['full_name']} ({repo['stargazers_count']} stars)")

Microservices Communication

# Service-to-service communication with retry and circuit breaker
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():
        user_id = response.json()["id"]
        print(f"✅ User created with ID: {user_id}")
    else:
        print(f"❌ Failed to create user: {response.status_code}")
except Exception as e:
    print(f"🔄 Service call failed after retries: {e}")

Real-time Applications
