What are some examples of using Zerolog in Go?

Can you provide some examples of how to use Zerolog in a Go application?

Sure! Zerolog is a structured logger for Go. Here's a simple example:

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

func main() {
    // Set the global log level
    zerolog.SetGlobalLevel(zerolog.InfoLevel)

    // Create a logger
    log.Info().Msg("This is an info message")
    log.Error().Err(err).Msg("This is an error message")
}

What are the benefits of using Zerolog over other logging libraries?

Zerolog is very efficient and produces minimal overhead. It also supports structured logging, which makes it easier to query logs.

Can I log JSON objects with Zerolog?

Yes, you can log JSON objects easily. For example:

log.Info().Interface("user", userObject).Msg("User logged in")

How do I configure the log output format?

You can configure the output format by using the zerolog.ConsoleWriter for pretty printing or by setting a custom output writer.
