Various functions that I use in projects

Logging

Using

• Zap logger by Uber, https://github.com/uber-go/zap
• Lumberjack https://pkg.go.dev/gopkg.in/natefinch/lumberjack.v2

Levels

• Debug
• Info
• Warn
• Error
• DPanic
• Panic

Init

var lg *zap.SugaredLogger

func init() {
	lg = log.InitWithConsole(zapcore.DebugLevel)
}

Set level

lg = log.SetDebugLevel()

lg = log.SetInfoLevel()

etc...

Log

• Simple: log.Info("hello")
• Formatted: log.Infof("hello %s", "world")
• Structured: log.Infow("hello", "var1", 12, "var2", 24)
