## 🌟 What Makes VELOCRIUM Special?

VELOCRIUM is not just another HTTP client. It's a **complete solution** that combines the elegance of `requests`, the power of `httpx`, and adds **intelligent features** that save you hours of development time.

```python
# This simple code does SO MUCH under the hood:
import velocrium

client = velocrium.Client(
    retry=velocrium.Retry(max_attempts=3),  # ✅ Auto-retry with backoff
    cache=velocrium.Cache(ttl=300),          # ✅ Smart HTTP caching
    rate_limit=velocrium.RateLimit("100/min") # ✅ Built-in rate limiting
)

response = client.get("https://api.example.com/data")  # 🚀 One line, all features!
```

## 📦 Installation

```bash
# Basic installation
pip install velocrium

# With Redis caching support
pip install velocrium[redis]

# With all optional features
pip install velocrium[all]
```

**Requirements:**
- Python 3.8+
- Works on Windows, macOS, Linux

---

## 🎯 Quick Start

### Basic Usage - It's That Simple!

```python
import velocrium

# Create a client
client = velocrium.Client()

# Make a request (works in sync context)
response = client.get("https://api.github.com/users/octocat")
print(response.json())

# Or use async (same API!)
async def fetch():
    response = await client.get("https://api.github.com/users/octocat")
    return response.json()
```

### With All the Power! 🔥

```python
import velocrium

# Configure once, benefit everywhere
client = velocrium.Client(
    base_url="https://api.example.com",
    
    # Auto-retry failed requests
    retry=velocrium.Retry(
        max_attempts=3,
        backoff="exponential",  # 1s, 2s, 4s, 8s...
        jitter=True  # Add randomness to prevent thundering herd
    ),
    
    # Cache responses automatically
    cache=velocrium.Cache(
        ttl=300,  # 5 minutes
        backend="memory"  # or "redis", "disk"
    ),
    
    # Rate limiting (never get throttled!)
    rate_limit=velocrium.RateLimit("100/minute"),
    
    # Sensible timeouts
    timeout=velocrium.Timeout(
        connect=5,
        read=30,
        write=10
    ),
    
    # Authentication
    auth=velocrium.BearerAuth("your-token-here")
)

# Now every request uses all these features automatically! 🎉
response = client.get("/users")
```

## 🔥 Advanced Features

### Request/Response Hooks

```python
def log_request(request):
    print(f"→ {request.method} {request.url}")
    return request

def log_response(response):
    print(f"← {response.status_code} ({response.elapsed}s)")
    return response

client = velocrium.Client(
    hooks={
        "request": [log_request],
        "response": [log_response]
    }
)
```

### Batch Requests

```python
# Execute multiple requests in parallel
with client.batch() as batch:
    batch.get("/users/1")
    batch.get("/users/2")
    batch.post("/users", json={"name": "John"})

# All executed concurrently!
responses = await batch.execute()
```

### Custom Retry Strategies

```python
from velocrium import Retry

# Exponential backoff with jitter
retry = Retry(
    max_attempts=5,
    backoff="exponential",
    base_delay=1.0,
    max_delay=60.0,
    jitter=True
)

# Linear backoff
retry = Retry(
    max_attempts=3,
    backoff="linear",
    base_delay=2.0
)

# Constant delay
retry = Retry(
    max_attempts=10,
    backoff="constant",
    base_delay=0.5
)
```

## 📊 Benchmarks

### Request Speed Comparison

```
╔══════════════╦═══════════╦═══════════╦═══════════╗
║   Library    ║  Simple   ║  Retries  ║  Caching  ║
╠══════════════╬═══════════╬═══════════╬═══════════╣

╚══════════════╩═══════════╩═══════════╩═══════════╝
```

### Memory Usage

```
VELOCRIUM:  12.3 MB (with caching)
httpx:      8.5 MB
requests:   6.2 MB
aiohttp:    11.8 MB
```

**💡 Note:** VELOCRIUM uses slightly more memory because it includes cache, retry state, and rate limiting - features that would add similar overhead to other libraries if implemented manually.

## 🎨 Real-World Examples

### API Client with Full Error Handling

```python
import velocrium
from velocrium.exceptions import HTTPError, TimeoutError, RetryError

client = velocrium.Client(
    base_url="https://api.example.com",
    retry=velocrium.Retry(max_attempts=3),
    timeout=velocrium.Timeout(connect=5, read=30)
)

try:
    response = client.get("/users")
    users = response.json()
    
except HTTPError as e:
    print(f"API returned error: {e}")
    
except TimeoutError:
    print("Request timed out")
    
except RetryError:
    print("All retry attempts failed")
    
finally:
    client.close()
```

### Rate-Limited Web Scraper

```python
import velocrium
import asyncio

# Never get blocked again!
scraper = velocrium.Client(
    rate_limit=velocrium.RateLimit("10/second"),
    retry=velocrium.Retry(max_attempts=5),
    timeout=velocrium.Timeout(read=60)
)

async def scrape_pages(urls):
    results = []
    for url in urls:
        # Automatically rate-limited and retried
        response = await scraper.get(url)
        results.append(response.text)
    return results

urls = ["https://example.com/page1", "https://example.com/page2"]
data = asyncio.run(scrape_pages(urls))
```

### Microservice Communication

```python
# service_a.py
import velocrium

# Configure for internal service mesh
api_client = velocrium.Client(
    base_url="http://service-b:8080",
    retry=velocrium.Retry(max_attempts=2),  # Quick fail for services
    cache=velocrium.Cache(ttl=60),  # Cache for 1 minute
    timeout=velocrium.Timeout(connect=1, read=5)  # Fast timeouts
)

def get_user_data(user_id):
    response = api_client.get(f"/users/{user_id}")
    return response.json()
```
