How do I set log levels using zap in Go?

In Go, you can set log levels using the Zap logging library, which provides a structured way to log messages with varying levels of severity. This example demonstrates how to configure different log levels and use them effectively in your application.

package main import ( "go.uber.org/zap" ) func main() { // Create a new logger with development configuration logger, err := zap.NewDevelopment() if err != nil { panic(err) } defer logger.Sync() // flushes buffer, if any // Setting various log levels logger.Debug("This is a debug message") logger.Info("This is an info message") logger.Warn("This is a warning message") logger.Error("This is an error message") logger.DPanic("This is a critical debug panic message") logger.Panic("This is a panic message") logger.Fatal("This is a fatal message") }
