logger

Logger

This package implements a logger using zerolog that should be used for application logging.

Usage

Importing the package

import github.com/nawiridigital/pkg/logger

Creating logger

Simplest way to instantiate a new logger is

l := logger.New(nil)

The New() constructor function takes in a logger configuration object

type Config struct {
	LogMode string
	Service string // unique name 
}

LogMode can be any of

	LModeSilent = "SILENT"
	LModeTrace  = "TRACE"
	LModeInfo   = "INFO"
	LModeWarn   = "WARN"
	LModeError  = "ERROR"
	LModeDebug  = "DEBUG"

Setting default logger

Once you create a logger instance you can set it as the default logger in your application

// create a logger instance
l := logger.New(nil)
// set it as default logger instance
logger.SetDefaultLogger(l)

// fetch the default logger instance
l = logger.Get()

Using the logger

Usages of the logger should be similar to a zerolog.Logger instance

l := logger.New(nil)
l.Info().Msg("example log")
l.Err().Error(err).Msg("database error")
