Quick Reference

// Basic usage
dd.Info("message")                        // → Package Functions
dd.InfoWith("msg", dd.String("k", "v"))   // → Package Functions + Fields

// Create a custom logger
logger, _ := dd.New(dd.DefaultConfig())    // → Package Functions + Config
logger.WithFields(fields).Info("msg")      // → Logger + Entry

// File output
fw, _ := dd.NewFileWriter("logs/app.log", dd.DefaultFileWriterConfig())  // → Writers

// Security
sec := dd.DefaultSecurityConfig()          // → Security
audit, _ := dd.NewAuditLogger(dd.DefaultAuditConfig())  // → Audit
