Installation

  go get github.com/go-mods/zerolog-quick

Usage

Default JSON Logger

The default logger is a JSON logger that writes to os.Stderr:

import log "github.com/go-mods/zerolog-quick"

func main() {
    log.Info().Msg("This is an info message")
}

Console Loggers

Plain Console Loggers

The plain console logger writes to os.Stderr and does not use any colors:

import (
    log "github.com/go-mods/zerolog-quick"
    "github.com/go-mods/zerolog-quick/console/plain"
)

func main() {
    // Message only
    log.Logger = plain.Message
    log.Info().Msg("Info message")
    // Date and message
    log.Logger = plain.DateMessage
    log.Info().Msg("Info message with date")
    // Date, time, and message
    log.Logger = plain.DateTimeMessage
    log.Info().Msg("Info message with date and time")
    // Date, level, and message
    log.Logger = plain.DateLevelMessage
    log.Info().Msg("Info message with date and level")
    // Date, time, level, and message
    log.Logger = plain.DateTimeLevelMessage
    log.Info().Msg("Info message with date, time, and level")
}

Colored Console Loggers

The colored console logger writes to os.Stderr and uses colors:

import (
    log "github.com/go-mods/zerolog-quick"
    "github.com/go-mods/zerolog-quick/console/colored"
)

func main() {
    // Colored message
    log.Logger = colored.Message
    log.Info().Msg("Colored info message")
    // Colored date and message
    log.Logger = colored.DateMessage
    log.Info().Msg("Colored info message with date")
    // Colored date, time, and message
    log.Logger = colored.DateTimeMessage
    log.Info().Msg("Colored info message with date and time")
    // Colored date, level, and message
    log.Logger = colored.DateLevelMessage
    log.Info().Msg("Colored info message with date and level")
    // Colored date, time, level, and message
    log.Logger = colored.DateTimeLevelMessage
    log.Info().Msg("Colored info message with date, time, and level")
}

Custom Logger Configuration

You can create custom logger configurations using the zerolog.New() function and the zerolog.ConsoleWriter options. For example:

import (
    "os"
    "github.com/rs/zerolog"
    log "github.com/go-mods/zerolog-quick"
)

func main() {
    customLogger := zerolog.New(
        zerolog.ConsoleWriter{
            Out: os.Stdout,
            NoColor: false,
            TimeFormat: "2006-01-02 15:04:05",
            PartsOrder: []string{
                zerolog.TimestampFieldName,
                zerolog.LevelFieldName,
                zerolog.MessageFieldName,
            },
		},
    ).With().Timestamp().Logger()
    log.Logger = customLogger
    log.Info().Msg("Custom logger message")
}
