Quick Start

Basic Usage with Logging

import asyncio
from cloudflare_saas import (
    CloudflareSaaSPlatform, 
    Config, 
    configure_logging, 
    LogLevel
)

async def main():
    # Configure logging
    configure_logging(level=LogLevel.INFO)
    
    # Load config from environment
    config = Config.from_env()
    
    # Initialize platform
    platform = CloudflareSaaSPlatform(config)
    
    # Create tenant
    tenant = await platform.create_tenant("Acme Inc", "acme-123")
    
    # Deploy site
    await platform.deploy_tenant_site(
        tenant.tenant_id,
        local_path="./acme-site"
    )
    
    # Add custom domain
    domain_status = await platform.add_custom_domain(
        tenant.tenant_id,
        "www.acme.com"
    )

asyncio.run(main())

)

Logging

Configure Logging

from cloudflare_saas import configure_logging, LogLevel, LogFormat

# Simple console logging
configure_logging(level=LogLevel.INFO)

# Detailed file logging
configure_logging(
    level=LogLevel.DEBUG,
    log_format=LogFormat.DETAILED,
    log_file="cloudflare-saas.log"
)

# JSON logging for production
configure_logging(
    level=LogLevel.WARNING,
    log_format=LogFormat.JSON,
    log_file="/var/log/cloudflare-saas.log",
    enable_console=False
)

Log Levels

• DEBUG: Detailed diagnostic information
• INFO: General informational messages
• WARNING: Warning messages
• ERROR: Error messages
• CRITICAL: Critical errors

Log Formats

• simple: Minimal output INFO: message
• detailed: With timestamps and source 2025-12-17 10:30:45 - Module - INFO - [file.py:65] - message

Using Loggers in Your Code

from cloudflare_saas import get_logger, LoggerMixin

# Get a logger
logger = get_logger(__name__)
logger.info("Starting operation")

# Use in a class
class MyService(LoggerMixin):
    def do_work(self):
        self.logger.info("Working...")
