loggo

loggo is a simple logging package for Go applications. It provides structured logging with multiple handlers and context support.

Features:

• Structured logging with JSON format
• Multiple handlers for logging to files and stdout
• Configurable log levels
• Context support for adding operation IDs to logs
• Helper function to generate unique operation IDs

Installation:

go get -u github.com/jonesrussell/loggo

Usage:

1. Create a new logger instance specifying the log file path:

import (
  "github.com/jonesrussell/loggo"
)

logger, err := loggo.NewLogger("/path/to/logfile.log")
if err != nil {
  // handle error
}

1. Use the logger methods to log messages with different levels:

logger.Debug("Starting application")
logger.Info("Processing request", "user", "john")
logger.Warn("Unexpected error", "error", err)
logger.Error("Failed to connect to database", err)

1. Add operation IDs to logs for context:

operationID := loggo.NewOperationID()
logger = logger.WithOperation(operationID)

logger.Info("Processing payment", "operationID", operationID, "amount", 100)
