How can a logging mechanism be integrated into your application?

In Go, to implement logging, you can use the standard log package or third-party libraries such as logrus or zap. For basic logging, it is sufficient to import the log package and use functions like log.Println(), log.Fatalf().

Example using the standard package:

import (
    "log"
)

func main() {
    log.Println("Application started")
    // ...
}

For more advanced logging (log levels, formatting, output to file), third-party libraries are used. For example, with logrus, you can configure log levels and output format:

import (
    log "github.com/sirupsen/logrus"
)

func main() {
    log.SetFormatter(&log.TextFormatter{FullTimestamp: true})
    log.SetLevel(log.InfoLevel)

    log.Info("Informational message")
    log.Warn("Warning")
}

Thus, the logging mechanism is connected by importing the necessary library and configuring logging parameters at the start of the application.
