How do I structure logs with fields using zerolog in Go?

In Go, you can structure logs with fields using the `zerolog` logging library. This allows you to log with context, making it easier to track and manage logs. Here's how you can do it:


        import (
            "github.com/rs/zerolog"
            "github.com/rs/zerolog/log"
            "os"
        )

        func main() {
            // Set the global logger to log to stdout in JSON format.
            log.Logger = zerolog.New(os.Stdout).With().
                Timestamp().
                Logger()

            // Log messages with structured fields.
            log.Info().
                Str("component", "auth").
                Str("user", "john_doe").
                Msg("User logged in")

            log.Error().
                Str("component", "database").
                Err(err).
                Msg("Failed to connect to database")
        }
