Log

A high-performance, buffered, rotating file logger for Go applications with built-in disk management, operational monitoring, and framework compatibility adapters.

✨ Key Features

• 🚀 Lock-free async logging with minimal application impact
• 📁 Automatic file rotation and disk space management
• 📊 Operational heartbeats for production monitoring
• 🔄 Hot reconfiguration without data loss
• 🎯 Framework adapters for gnet v2 and fasthttp
• 🛡️ Production-grade reliability with graceful shutdown

🚀 Quick Start

package main

import (
    "github.com/lixenwraith/log"
)

func main() {
    // Create and initialize logger
    logger := log.NewLogger()
    err := logger.ApplyConfigString("directory=/var/log/myapp")
    if err != nil {
        panic(err)
    }
    defer logger.Shutdown()

    // Start logging
    logger.Info("Application started", "version", "1.0.0")
    logger.Debug("Debug information", "user_id", 12345)
    logger.Warn("Warning message", "threshold", 0.95)
    logger.Error("Error occurred", "code", 500)
}

📦 Installation

🎯 Framework Integration

The package includes adapters for some popular Go frameworks:

// gnet v2 integration
adapter := compat.NewGnetAdapter(logger)
gnet.Run(handler, "tcp://127.0.0.1:9000", gnet.WithLogger(adapter))

// fasthttp integration
adapter := compat.NewFastHTTPAdapter(logger)
server := &fasthttp.Server{Logger: adapter}

See Compatibility Adapters for detailed integration guides.

🏗️ Architecture Overview

The logger uses a lock-free, channel-based architecture for high performance:

Application → Log Methods → Buffered Channel → Background Processor → File/Console
                ↓                                      ↓
            (non-blocking)                    (rotation, cleanup, monitoring)
